JAVA Industry Updates

Trends in Java

In recent times, Java has evolved into one of the top-rated programming languages among various organizations in the market. There is a consistent release of updates related to Java due to its depth of features, stability along with predictability. It has made it easy for developers to accomplish their task on time. Apart from the developers, even the organizations are making it into their upcoming applications. Get involved in Java by joining our Java Training in Chennai.

There has been an enormous feature that has made it reach the top on the list. Some of them are enlisted below:

Independent of the platform– It can be run over any system due to the presence of intermediate format. The developers can write the program once in Java language and will be able to execute it on various platforms such as Linux, Windows, or Mac without the necessity of re-compilation.

Familiar– Java is nearly the same as that of C/C++ and is deployed for fixing the disadvantages occurring due to the latter. Therefore, if the developer is well-versed with C/C++ language then might be very simple for them get along with Java.

High performance– It yields relatively high performance when compared with other languages. Moreover, it is possible to write computer intensive code that can be interfaced with the Java platform in order to improvise the performance with the use of Java Native Interface.

Multithreaded– This platform is designed along with multithreading capabilities for built-up into the language, which means the developer will be able to build applications with different concurrent threads of activity that results in highly responsive applications.

Robust– It is considered to be very strong with the collection of garbage in an automated way with complex free memory management. Thus, it is preferred by the companies.  

Secure– It is designed in such a way that it aids the user in implementing their creativity for various applications. It is very tough for any virus to affect applications built by deploying Java. Be a pro in Java by enrolling yourself into our Java Course in Chennai.

This year’s latest release in Java is Java 10, and Java 11.  However, support for all the older versions is estimated to end by 2020. In addition, JDK 11 is the one which has been planned to get the long term support provided by Oracle.

Java 9

It was released in September 2017 making significant changes along with necessary updates to Java 8. The most important update amidst them is considered to be the new architecture along with a different structure to Java. It makes use of a modular structure rather than making use of the traditional model.

The advantage of modularity is the ability in setting up customized configurations of various modules and removal of any unnecessary modules. That could greatly increase the efficiency along with the scalability in various apps built over Java. The eventual goal of modularity push is to make Java more approachable to smaller-scale machines, particularly smartphones.

Second, the most important improvement is the function of JShell Read-Eval-Print-Loop. Moreover, developers are able to now get immediate feedback on how the code is working. For getting more knowledge in Java join FITA, best Java Training Institute in Chennai.

Java 10

Its release happened in March 2018 not more than six months after the launch of Java 9. It didn’t make any crucial change but was helpful for some basic issues to be fixed. And the very crucial feature was the inclusion of new garbage interface for its collection in Java 10, which organizes and also concentrates source code for the collection of the collection into a single place instead of scattered the files and patching throughout the environment. This new version of Java also made inferences about the variable type when the developer makes use of the “var” keyword.

 Java 11

This is the latest version that has been released this year in the month of September, which marks the deadline of a monumental shift in the Java ecosystem. Some of the preplanned updates included in this are standard browser updates along with upgrading the Java to Unicode 10, which was previously making use of Unicode 8.

Java 11 will definitely help the developers to get rid of the support for Java EE along with the COBRA modules. Since the new long-term release of support for Java 11 it has been considered as a standardized improvement from the previous versions such as Java 9 and 10, which applies to the customers with commercial support from Oracle. In addition, public updates related to Java 11 will come to end after a period of six months when the next version Java 12 will be released into the market.

JDK 11 is elegant light on the things that modify the way of coding by developers. Some of the new trends in the market for JDK 11 are listed below:

  • JDK 11 new string methodology
  • Pattern with predicate utility methods
  • is Empty
  • Files utility method
  • Epsilon garbage collector
  • Time unit convert

Latest frameworks of Java Virtual Machine

There are so many virtual machine languages for java like Clojure, Groovy, JRuby, Jython, Kotlin, and Scala. These languages have been evolving in the software industry for a relatively long time and let us have a look at the new JVM languages as of 2019. JVM is the virtual language of java which is designed for the java machines and it changes the java code into byte code. Join the best Java Training to know about the multiple perspectives of a programming language like JVM, JDK, and JRE.

Java programmers are using these JVM languages for the development due to certain positives. The advantages of JVM over java are in JVM the functions are used as parameters; high-level complicated functions are easily handled with the parameterization, case matching and compact code, and the functions of the compiler. Join Java Training in Porur to be confident in the multiple concepts in the language. Programmers use primary languages and secondary languages in their coding and make their builds as an efficient one. The knowledge about multiple languages has become the predefined criteria for an experienced developer. Let us have a look at the Scala, Kotlin and Groovy programming language for the JVM as they are widely used. Class loader, method area, JVM language stacks, heap, native method stacks, PC registers, native method stacks, execution engine, native method interface, and native method libraries are the components which form the architecture of JVM. Join the best JAVA Training Institute in Chennai to gain the knowledge from the expert trainers from the scratch to the advanced level.


Scala was introduced to the industry in the year 2008 by the Martin Odersky. Scala is largely used in the data science projects and it is written to target the Java virtual machine. Scala developers do not have the need to learn the other programming languages but due to the announcement from Google for the spring and Google, the Scala is now replaced for the Kotlin. Some of the features of Scala were introduced in Lambdas and Stream. Scala is a very good language to learn for the Java developers. Play, AKKA, and spark are the popular frameworks of the Scala. Learning a new language boost the knowledge about the different data structure, coding designs, different types of the algorithm, and different approaches to the problem. So learning new languages like Scala will help the programmers to write code better, read the better code, debug code and run the code quickly. Java Training with the Best Java Training Institute in Chennai makes your bio-data with high priority due to the programming language knowledge.

Many giant companies like Uber, Sony, Amazon, and Autodesk are using the Scala language to enhance customer satisfaction with a wide range of reachable services. Scala is the perfect blend of the functional programming and the object-oriented programming. The parts of java language where some restrictions are levied are unleashed in the Scala language which increases the productivity.

Some of the good features in the Scala language is immutable data structures with no effects on the environment, the simple one-liner language with less punctuation, short syntax, condensing map and filter, and finally, the code will support both the multiple inheritances and different types of capabilities.


In the year 2011, JVM language Kotlin was introduced and this is the official language for the Android development. The announcement regarding kotlin was made by Google in the year 2017. Kotlin is the language alternatively used for Java and it is the official language for android. Kotlin was designed by the company called Jet brains and it is used as an open source platform by the programmers. The simplicity in the language made this language as a popular language. For instance fun keywords are used in the Kotlin, semicolons which are mandatory in the java are optional in the Kotlin language. The keywords and ranges are well used in the Kotlin language. Java Classes in Chennai offers the training to make the learning curve flat from the upsurge.

Functional programming and object-oriented programming are two different concepts in the programming world. In functional programming functions cannot be stored in objects and in object-oriented programming, the programming is based on objects. For the programs which can be divided into smaller parts, object-oriented programs yield better results. Join the Best JAVA Training in Chennai and become a professional with high salary package in the industry.

When converting the java program into kotlin it is clearly known that kotlin is handy language it supports the object-oriented nature of java. The other classes inherit with the keywords in the Kotlin classes whereas in the case of Java the final keyword is marked as inheritable. In the case of overriding the methods are marked as open and the subclass is marked as an override. The Kotlin makes the things explicit and it is not operated with the default operations. JAVA Training in Chennai is for the beginners and experienced with ample interest into the coding.

The checked exceptions in Java are lacking in the kotlin. The expenditure on using Java and kotlin is the same. The java set only properties are easily fixed in the Kotlin. Some of the new things in kotlin for the Java developers in Kotlin are the extension functions, support functional programming and add coroutines. Java Training in T.Nagar is the best place for learning and understanding the difference between the multiple programming languages.

There are similarities in between Scala and Kotlin like the notations like immutable declarations using va1, mutable declarations using var, narrow in the declaration of lambda function, and the usage of a single arrow and double arrow. The getters and setters are available in a java class and calling the java code from the kotlin language work well in the applications. These features are common in Java and kotlin and the name for getter and setter in Kotlin is properties. JAVA Training in Adyar focus the syllabus with the latest updates from the industry and provides the training needed to clear the interview with less effort.


Groovy is simple language than Java and it is used for unit testing and for the virtual machine language. Groovy first version which is Groovy 1.0 was released in the year 2007 and the second version which is Groovy 2.0 was released in the year 2012. Java Training in Tambaram is designed to satisfy the learning needs of the people staying at Tambaram. For the Java developers, the learning curve for Groovy is flat and the behavior of Groovy is simple to understand for Java developer. For instance, in Groovy the operators call equals() method but will not compare the instances.

J Unit along with Groovy syntax is used for the testing process. Java Training in OMR has a good track record for the training and placement in the training industry. The Spock is the framework which is used to write the better testing scripts with the Groovy. For parameterized tests, it gives a graphical representation.

Expectations with JDK 13

JDK is expected in the year 2019 with many attributes and the developers are focused towards quality before the release. The multiple lines of source code are covered by raw string and it is the new attribute expected from the JDK 13. Rawstring is a literal with string in which the escaping rules are eliminated and everything is literal or direct. This is the feature which is expected with the JDK 12 and it is postponed to JDK 13. The characters with the sequence are described without java indicators and these strings are focused towards grammar apart from Java. After the testing process the new attributes are added to the JDK 13 with the quality in the production. JDK 14 is expected with high quality with the raw string after its first release. Let us take a look at how the raw string makes the functions of java simpler. Join the Java Training in Chennai at FITA to explore the new trends in Java the legendary technology.

Simplification is the most needed part in the programming language which derived through the library and the JDK code. Simple codes and readable codes are enhanced for the back end support to optimize the performance. The feature of multi-line raw string is available in many other languages like Groovy, Java script and Python for the enhancement of the performance.

This reduces the usage of the java escapes and the java line terminator for keeping the character sequence readable with the code. The concept of string interpolation is not added to the raw string and in future it is expected to take part in the raw string.

Some of the advantages of these strings are already added in the RSL and some are not added. The enhancements can be with the line support, trim, and margin management and escape management by using raw string.

Beta implementation is added in the JDK and switch expressions is added which help for the behavior with control over the flow. This helps for the blocking of calls, synchronous and makes the blocking as free.Java Course in Chennai at FITA is conducted with veteran trainers who are from the top software companies with good record of performance.

Pending releases of Java

Project loom is the other feature which is not added to the Java fully and this helps for optimizing the performance with the simple abstraction and leaves less number of footprints. This manages the threads efficiently and it introduces the fibers as light weight with the usage of JVM. The memory and the task switching with the fibers are almost close to zero.The ultimate need of this is to add the light weight thread to the java eco system.

The java program is designed to use the threads easily and the primitives are synchronized with this. If there is mismatch in the orders then it is difficult to handle for the server. Integration with the other language and integration with the code is one of the important functions which API should have. Many asynchronous API are created in the Java ecosystem to handle the integration part in Java.It helps to run the existing code and reduces the time also. the REST service or servlet takes more time when compared to this.


This feature help for POJO class and it makes the coding part with this easier.Java Training in Chennai is highly demanded as many projects are based out of java.

Future of Java

Java is used for the web development, mobile development and the desktop development. Cross platform mobile apps are developed using the java platform with the help of SDK. Java standard libraries, Maven, JHipster, Guava, apache commons, hibernate-ORM, Junit, Mockito, log4j, google-gson, and SIf4j are the wide range of libraries available in java for the making the complex part in the coding easy.There are troubles in moving from the versions like the 8 to 12 or 11.

The version change is a problem in the software industry with respect to the investment and it demands to change the whole functionalities. Simplification for the container management and the version change are given more importance when thinking about the future of Java. Competition with JVM is initialized by the other languages like the kotlin and scala. Learn Java Course in Chennai to enter in to the vast industry as many other technologies need java background.

Powerful languages are needed to empower the emerging technologies like Artificial intelligence and machine learning and thus Java is demanded to build the complicated large systems. The coding simplification, changes in the data objects and data types help for the innovation of the new technologies.   The research and production team java told that there will be a released for every 6 months to widen the usage and bridge the gap in the issues with the language. The legacy technologies support the emerging technologies to make the support for the business and technology in multiple ways. Java Training in Chennai is designed for the beginners and experienced like the model is basic level course and the advance level course.

Java Sample Resumes

Java Tutorial

A well-known programming language in the field of Information Technology is Java Training in Chennai, which was designed for the constant flow of code on any machine. This was considered a treasure due to its wide usage on any platform or architecture. Java Training in Chennai was a predominant thing in Ethiopia at that time. Java is an island, which is familiar for its coffee beans.

Java is one of the popular computer programming languages.  It is class based and object oriented language.  Java is owned by Oracle company and its running in 3 billion devices around the world. Java will be safe for many years with the plenty of Java developers, running devices and companies adapting. Java is developed by James Gosling at Sun Microsystems and released in the year 1995. It is now acquired by Oracle Corporation. This language has similar syntax from C and C++.

Here we discuss about the features of Java programming in brief as listed below

1, Java is platform independent

2, Java is an Object oriented language

3, Java is very fast to use

4, Java provides features for security

5, Java is a huge standard library

The latest edition of Java programming is Java SE 8. Many configurations built to suit different platforms. The new version J2 is called as Java SE, Java EE and Java ME accordingly.

Here we require a Pentium 200 MHz computer with RAM of 64 MB. The following software required for these are Windows xp or Win 7 or Win 8 or Linux 7.1, Java JDK 8, Microsoft Notepad or any text editor. The basic concepts followed in Java are Inheritance, Polymorphism,  Abstraction, Classes, Objects,  Instance, Method.

James Gosling introduced Java in June 1991which was known as Oak named after an oak tree outside Gosling’s office and got its name changed as Java over a period. Thus, the journey of Oak becoming to be known as Java ends here.

Java Training in Chennai was not an open source initially, it was under the influence of GNU General Public License, and Sun released the open source version of Java in November 2006. In addition, by the month of May 2007 it was completely code free language.

The evolution of Java till date is listed below:

  • JDK Beta (1995)
  • JDK 1.0 (Jan 1996)
  • JDK 1.1 (Feb 1997)
  • J2SE 1.2 (Dec 1998)
  • J2SE 1.3 ( May 2000)
  • J2SE 1.4 (Feb 2002)
  • J2SE 5.0(Sep 2004)
  • Java SE 6 (Dec 2006)
  • Java SE 7(July 2011)
  • Java SE 8 (Mar 2014)
  • Java SE 9(Sep 2017)
  • Java SE 10(Mar 2018)
  • Java SE 11(Sep 2018)
  • Java SE 12 (Mar 2019)

Tomcat is considered the desirable application server for the open source programming language-Java. For the usage of Java in any web browser, it is necessary to have a Java plug-in.

Java has unlocked its doors for the interaction with other companies in order to extend the Java community. With the back-to-back, release of versions in Java its expectation for lots of changes in the near future. Thus, Java Training is very popular in the market to become successful as a programmer. FITA is rated as no.1 in Core Java Training in Velachery.

Java Training in Chennai- Outline

There are many programming languages present in the market and Java Course has secured its place right at the top of the list. Sun Microsystems developed it in the year 1995.  James Gosling is the one behind its innovation. The recent update released by them for Java is Java SE 11(18.9 LTS) launched in the month of September 2018.

Pattern with Predicate Utility Methods, Optional.isEmpty, Epsilon Garbage Collector are some of the noted features of Java SE 11.  Soon after the launch of Java its popularity made openings for multiple configurations in order to for different platforms like J2EE, J2ME and the list continues.

Its preference amidst developers is keep on increasing as program once written in
Java Training in Chennai can be executed irrespective of the platform it is implemented.

How is Java related to C and C++

The syntax of Java Course is derived from C and the object model is derived from C++. The programmers who are well versed with C/C++ language will be easily learning Java. Moreover, Java developers do not create a new thing but modify the already existing. As there is many similarities prevailing between Java and C++, Java is known as the Internet version of C++. Java was not created for the replacement of C++ whereas its creation is to support for getting solution issues, which arises in C++. Hence, Java Course in Chennai is preferred over others.

How is Java related to C#

C# language was developed by Microsoft, which has similar features with Java. Both of them are using the general style syntax. FITA, is considered as the best Java Training Institute in Chennai.

Contribution of Java to Internet


Applet is one of the contribution of Java, which reframed the networked program across the world. It is designed for the transmission over Internet and executed by web browser, which is compatible to Java Training. If user clicks on anything, which consists of Applet, then it will download applet automatically.

Applet runs within the web browser, which works at the client side. It is embedded in a HTML page with the use of OBJECT or APPLET tag.

Points to remember:

  • Every applet is a sub-classes of java.applet.Applet class.
  • They have never been a stand-alone program as they run inside an apple viewer or a web browser. Moreover, JDK enables a standard viewing tool for an applet namely applet viewer.
  • For an applet window the output is not done using System.out.println() whereas done using AWT methodologies.
  • For the execution of applet at main() method is not used in the beginning.

 The various methods are:

  • init( ) : This is the first method which is called for the initialization of variables. Moreover, it is called only onceduring run time.
  • start( ) :It is the next step after init() and also called in order to restart an applet once it is stopped.
  • paint( ) : The paint( ) is called every time AWT-based output of an applet needs to be redrawn, which can occur for many reasons. For instance, the window where the applet is running may be overwritten by another window. Or else even the applet window might be minimized and later on restored.
  • On another instance itis also called when the execution of applet begins.
  • stop( ) : This method is called when a HTML document having is left by the web browser. When stop( )is called, the applet is under execution.
  • destroy( ) :This  is called when the environment is the key factor in determining which applet is needed to be removed completely from the memory.

Features of Applets over HTML

  • It displays dynamic web pages of any web application.
  • Plays sound files.
  • Plays animations
  • Displays various documents

It made numerous changes in the world of Internet as the objects were able to progress freely. The 2 categories of information that are transmitted between server and client namely passive and dynamic information.

Let us get into the topic of what makes Java more prominent

Complex-free: Java was designedfor the developers to write programs with ease. It is considered easier than C++ as there is automatic memory allocated.

Multi-threaded: The capacity of a program to perform many tasks simultaneously within the program.

Object-Oriented: Allows the user in creation of modular programs along with reusable code.

Distributed: Designed to make allocated computing simple along with the networking capability.

Platform-Independent: Moving it from one system to another can be done with much ease.

Secure: The Java language is highly secured when compared with other programming languages.

Robust: It helps in eliminating error due to the presence of time error check along with runtime check.

StackAllocation: This helps the user to store data with ease.

High Performance:Java set up high performance due to the presence of just-in-time compilers.

Thus, enroll yourself into Java Training at FITA for a blissful future.

History of Java

The project Java was initiated in the year 1991 by James Gosling, which was originally called “Oak” named after the Oak tree, which stood in the entrance of James’s office. Then it was renamed as Green and after a long time it got the name ‘Java’. Its public implementation happened in the year of 1995 by Sun Microsoft.

After this it was made open source in the year 2006under the terms of GPL. Finally, on May 8th of 2007 the process of making it code free was accomplished. Java Classes in Chennai is of great opportunity for IT professionals.

Tools in need

There are certain specifications to be fulfilled for running Java in your system. As Java Training  is fetching more students it is indeed to have the specific hardware and software to work on Java.  They are specified below:

  • Pentium 200-MHzComputerwith64 MB of RAM
  • Linux 7.1 or Windows xp/7/8 operating system
  • Java JDK 8
  • Microsoft Notepad


A program in Java is acluster of object, which communicate by calling upon each other’s method.Let us concentrate on the various components present in Java syntax:

Class- It is the blueprint, which describes the state of the object supported by it.

Object- They have various states along with different behaviors.

Methods- It is always been a behavior.

Instance variables- Every object has a unique set of it.

Java Identifiers

Every component present in Java requires names. It may be used for classes, methods and variables that are known as identifiers. There are certain basic things to be remembered:

  • Identifier should begin with alphabet, underscore or currency character.
  • They are case sensitive.
  • The rest of the characters should be combination of characters.
  • Keyword should not be used as identifier.

Java Modifiers

It is indeed necessary to modify methods, class and other components. The modifiers are classified into two:

Non-access modifier: abstract, final

Access modifier: public, default

Java Variables

There are various Java variables:

  • Local Variables
  • Instance Variables (Non-static Variables)
  • Class Variables (Static Variables)

Java Enums

Java 5.0 consists of Enums, which restricts variable to have single predefined value form the given list. Enumsare used for the reduction of bugs in the code.

Java Keywords

There are certain reserved words that cannot be used as variableor constant namely: abstract, assert, Boolean,break, byte, case, catch, char, class,continue,const,default, else, double, float, final, do, enum, extends, if, for, implements, goto, int, import, interface, instanceof, native, long, package, new, public, short, private, return,strictfp, synchronized, throw, switch, static, transient,volatile, void, try, throws.

Comments in Java

It supports both single and multi-line comments, which is similar to C and C++.


The specialty of Java is classes can be derived from classes.


It is the arrangement between objects for the method to communicate.It plays crucial role for the inheritance.

Java – objects & Classes

Java is object-oriented language which includes:

  • Inheritance
  • Polymorphism
  • Abstraction
  • Encapsulation
  • Objects
  • Instance
  • Class
  • Object

Classes present in Java

There are 3 classes present in Java:

A class can contain any of the following variable types.

  • Local variables: These variables are defined inside methods, constructors or blocks.
  • Instance variables: variables aredefined within a class and outside any method.
  • Class variables: These are declared within a class, outside method, with static keyword.

How to Use Singleton Class?

Its work is to control the object creation, which in turn limits the number of objects to one. As there is singleton instance, its occurrence will be restricted to one per class. Join our Java Classes in Chennai and get more knowledge in it.

How to Create an Object

A class in Java administers the blueprints for any objects. The steps involved in the creation of object are:

  • Declaration: A variable is declared with variable name and an object type.
  • Instantiation: The ‘new’ keyword is usedfor the creation of object.
  • Initialization: The ‘new’ keyword is pursuedby a call to a constructor.


The various operator available in Java are:

  • Bitwise Operators– &(bitwise and), ~ (bitwise compliment), | (bitwise or), >> (right shift), << (left shift), ^ (bitwise XOR), >>> (zero fill right shift).
  • Arithmetic Operators– + (Addition), * (Multiplication), % (Modulus), – (Subtraction), / (Division), ++ (Increment)
  • Assignment Operators – =, *=, +=, %=, |=
  • Logical Operators – || (logical or), && (logical and),! (logical not)
  • Relational Operators– == (equal to), < (less than), != (not equal to), <= (less than or equal to)
  • Misc Operators-Conditional Operator


There are over 3 billion devices, which run on Java script. Thus, joining Java Course in Chennai will be of great help for you to enter the IT sector. Few among them are listed below:

  1. Web based Applications such as, etc.
  2. Mobile
  3. Enterprise based Applications like banking applications.
  4. Robotics
  5. Desktop based Applications like media player, acrobat reader, etc.
  6. Embedded System
  7. Smart Card
  8. Games

Types of Java Applications

There are four types of applications, which can be generated with the use of Java programming:

1) Web Application

An application that can be executed on the server side along with creation of dynamic page is known a web application. Servlet, Struts, JSF, Spring, etc. are some of the technologies which are used in the creation of web applications.

2) Standalone Application

Standalone applications also known as window-based or desktop applications are traditional software, which are indeed necessary to be installed on every machine. There are various examples for standalone application such as antivirus, Media player, etc. AWT and Swing are deployed in the creation of Java.

3) Enterprise application

An application that is assigned in nature, such as banking applications, etc. is called enterprise application. It has many benefits of load balancing, high-level security, and clustering. Enterprise Java Beans is deployed for the creation of enterprise applications.

4) Mobile application

An application that is created for mobile devices is known as a mobile application. These days, Java ME and Android are used for the creation of various mobile applications.

Java platforms

The students with a considerable amount of knowledge in Java Training have good openings in the market. Java platforms are classified into:

1) Java Standard Edition

Java SE is a Java programming platform that consists of Java programming APIs like java.lang,, java.math, java.util, java.sql, etc. It has basic topics such as OOPs, Reflection, Regex, Exception, String, Inner classes, I/O Stream, Networking, AWT, Multithreading, Swing, Collection, etc.

2) Java Enterprise Edition

J2EE is an enterprise platform that is primarily used for the development of enterprise and web applications. It is erected on top of the Java SE platform. It also has topics such as Servlet, Web Services, EJB, JSP, JPA, etc.

3) Java Micro Edition

JME is a micro platform that is used in order to develop various mobile applications.

4) JavaFX

It is used in order to develop affluent internet application, which makes use of light-weight user interface API.

Difference between JDK, JRE, and JVM


Java Virtual Machine is an abstract machine and is called virtual machine as its existence is not physical. Moreover, it is a blueprint, which provides runtime environment for the execution of Java bytecode. In addition, execution of programs written in other languages is also possible.

All the three JVM, JDK and JRE are platform reliant due to the composition of all the operating systems that are unique. JVMs is availability us not constrained to any one hardware or software. For further information, join FITA, the best Java Training Institute in Chennai.

The tasks performed by JVM are:

  • Supply’s runtime environment
  • Loading of code
  • Verifying the code
  • Execution of code

What is JVM

JVM is a specification in which working of Java Virtual Machine is specified. Moreover, the implementation provider is not dependent on the choice the algorithm whose implementation is provided by Oracle. FITA, is among the top Java Coaching Centers in Chennai.

JVM provides description for the following:

  • Register set
  • Fatal error reporting
  • Memory area
  • Class file format
  • Garbage-collected heap

Java Variables

A variable is a container that possess the value when the java program is been executed. A variable is accredited with a datatype.

Variable is name given for memory location, which are classified into three types: instance, local, and static. Join our Core Java Training in Chennai and get the opportunity to enter the It sector.

There are two types of data types in java: primitive and non-primitive.


It is the fundamental unit of storage in any program.

  • The value that is stored in a variable can be altered during the process of the program execution.
  • A variable is just a name given to a memory location.
  • In Java, every variable must be declared before bringing into use.
  • Variable has always been a combination of vary + able.

Data Types in Java Training in Chennai

Data types define the different size, values as well, which can be stored in the variable. It is classified into two data types in Java:

Primitive data types: The primitive data types consists of boolean, byte, double, short, int, char, long and float.

Non-primitive data types: This include Classes, Interfaces, along with Arrays.

Java Primitive Data Types

In Java language, basic data types are the building blocks of data manipulation. The following are the fundamental data types that are available in the Java language. Become smart by joining our Java Training in Adyar.

They are classified into 8 types of primitive data types:

  • byte data type
  • char data type
  • short data type
  • boolean data type
  • float data type
  • int data type
  • long data type
  • double data type

Boolean Data Type

The Boolean data type is used for the storage of only two possible values either true or false. This data type is used for tracking of true/false conditions in simple flags.

Byte Data Type

The byte datatype also belongs to primitive data type, which has an 8-bit signed two’s complement integer. The value-range of byte datatype lies between -128 to 127 with the  minimum value -128 and the maximum value 127 with a default value as 0.

This is used in order to save memory in large arrays in which the memory savings is indeed necessary that saves space as a byte is 4 times smaller than integer. This can be used for the replacement  of “int” data type.

Short Data Type

It is a 16-bit signed two’s complement integer who’s value-range lies amid -32,768 to 32,767 considering minimum value as -32,768 and maximum value as 32,767. The default value in short data type is also 0.

It is similar to byte data type with respect to memory saving. Moreover, it is 2 times smaller when compared with integer.

Int Data Type

This data type is a 32-bit signed two’s complement integer with value ranging between – 2,147,483,648 to 2,147,483,647. The minimum value is considered to be – 2,147,483,648 and maximum value as 2,147,483,647 with a default value as 0.

This is broadly used as default data type for the integral values except if there is no problem with respect to the memory.

Long Data Type

This is a 64-bit two’s complement integer and consist of value-ranging between -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. Long datatype has minimum value as – 9,223,372,036,854,775,808 and with the maximum value as 9,223,372,036,854,775,807.

The default value is considered to be 0. This data type is deployed when there is need of range of values that is provided more than by int.

Float Data Type

This data type is single-precision 32-bit floating point with value range that is considered unlimited. It is favored to the usage of a float instead of using double if there is a need to save memory in large arrays of floating point numbers. This data type should never be used for the precise values like currency with a default value as 0.0F.

Double Data Type

This is a double-precision 64-bit IEEE 754 floating point with unlimited range of value. This data type is normally used for decimal values similar to float. The double data type should never be used for the precise values, like currency with a default value of 0.0d.

Java If-else Statement

Java if statement is deployed to test the condition and checks boolean condition of true or false.

The types of if statement in java are:

·         if statement

·         if-else-if ladder

·         if-else statement

·         nested if statement

Java if Statement

It runs the if block if the condition is true.



//code to be executed


Java if-else Statement

The Java if-else statement executes the if block when the condition is true otherwise else block is executed.



//code if condition is true


//code if condition is false


Java Nested if statement

The nested if statement serve the if block within another if block. In this, the inner if block condition runs only when the outer if block condition is true.

Java Switch Statement

The Java switch statement executes only one statement from multiple conditions. The switch statement works with long, byte, short, int, enum types, String. In other words, the switch statement is deployed for testing the equality of variable against multiple values.

Loops available in Java

In the various programming languages available, loops are used in order to execute a set of instructions repeatedly when some of the conditions are true. They are classified into three types:

  • while loop
  • for loop
  • do-while loop

Java for Loop

In Java, for loop is used for the iteration of a part of the program many times. If the number of iteration is steady, it is recommended for the usage of loop.

They are:

  • Labeled For Loop
  • Simple For Loop
  • Enhanced For Loop

Java Simple For Loop

A simple for loop is same as C or C++. Initialization of variable, condition check and increment or decrement value can be done. It has four parts:

Initialization: It is the initial condition that is executed when the loop begins. Here, initialization of we can initialize the variable, or we can use an already initialized variable. It is an optional condition.

Condition: It is the next condition that is executed every time to test the condition of any loop and continues the execution process until the condition is false. It must return boolean value either true or false.

Statement: The statement of the loop is executed each time until the second condition is false.

Increment/Decrement: The variable value can be incremented or decremented, which is an optional condition.

Java for-each Loop

The for-each loop is used to traverse collection in java. And is easier to implement than simple for loop as there is no need to increment the value along with the use subscript notation. It works on elements basis and not on the index. We get you trained in Java Course for a bright future.


for(Type var:array){

//code to be executed


Java Labeled For Loop

We can bear a name of each Java Training in Chennai for a loop. We can make use of label before the for a loop. It is indeed useful if we have nested for loop, with its help we can break/continue specific for a loop.




//code to be executed


Java Infinitive For Loop

If you use two semicolons ;; in the for loop, it will be infinitive for loop.



//code to be executed


Java While Loop

The Java while loop is used to iterate a part of the program several times. If the number of iteration is not fixed, it is recommended to use while loop.



//code to be executed


Java Infinitive While Loop

If you pass true in the while loop, it will be infinitive while loop.



//code to be executed


Java do-while Loop

The Java do-while loop is used to iterate a part of the program several times. If the number of iteration is not fixed and you must have to execute the loop at least once, it is recommended to use do-while loop.

The Java do-while loop is run at least once because condition is checked after loop body.



//code to be executed


Java Infinitive do-while Loop

If you pass true in \ do-while loop, it will be infinitive do-while loop.



//code to be executed


Java Break Statement

When a break statement is encountered within a loop, the loop is immediately terminated and program control resumes at the next statement following the loop.

The Java break is used in order to break loop or the switch statement. It breaks current flow of program at specified condition. In case of inner loop, it breaks the inner loop alone.

We can use Java break statement in all types of loops such as for loop, while loop and do-while loop. We will give training with the help of real time examples in FITA, the best Java Training in Chennai.




Continue Statement

The continue statement is used in loop control structure when you need to jump to the next iteration of the loop immediately. It can be used with for loop or while loop.

The Java continue statement is used to continue the loop. It continues the current flow of the program and skips the remaining code at specified condition. In case of inner loop, it continues inner loop.

We can use Java continue statement in all the type of loops like for loop, while loop and do-while loop. For any further knowledge in Java enroll yourself into our J2EE Training in Chennai.




Java Operators

It is used to perform an operation on variables and values. In this two terms are included operand and operator.

To explore more::JAVA Training in Chennai

Example :

int x=100 + 50

* Values are the operand

*The operation performed between two operands is defined as an operator. FITA is the no.1 JAVA Course in Chennai

Java Data Types

Specified data type only the variable in java. We cannot use all data types.

To explore more::JAVA Training in Chennai


int  x = 6;

float y=6.99;

char z=’a’;

boolean n=true;

string =”hello”;

Non-Primitive data types

It is a reference to data types. It was created by a programmer while coding   the program, it may be the Reference variables or Object variables

*Non-Primitive data types are used to call methods to perform                      certain actions

*It is not defined by java, it was created by the programmer

*Compare to primitive data types, Non-primitive is NULL does not       has a value

string s=”How are You”;


RESULT::4(java counts from the position 0)

String Concatenation

We can use + operator in between two strings to add them together. And also we can use Concat( ) to add two strings.You want a advance knowledge in java FITA advanced java training in chennai


string x=”Tamil”;

string y=”nadu”;

System.out.println(x +” “+y);


RESULT:: Tamil Nadu

{we have added an empty text(“ “)to create a space between those words}

Adding Numbers and Strings

Java uses the + operator for both the addition and concatenation.

*If you can use + for numbers it will add the numbers and give the result

*If you can use + for the string it will concat those strings. As we can see in the before Examples.FITA Best JAVA Training institute in Chennai

It is used to find the highest value between the two numbers given in the math function.





This method is used to find the lowest value  between the two numbers given in the math function


math.min(50, 30);



Using this function we can find the square root value of the given number

FITA JAVA J2EE Training in Chennai





This method returns the positive value of the integer give in the math function




Java Arrays

Using java array we can store the multiple values in a single variable, instead of declaring separate variables for each value.

FITA Best JAVA Training institute in Chennai

We have to declare the array using square brackets.

string [ ] x;

Then using curly braces we have to insert the values in the array, within double quotes and separated with a comma.

string [ ] x={“car”,”bike”,”scooty”};

Access the Elements of an Array

Refering the index number we can access the array.

Course for J2EE in FITA J2EE Training in Chennai


string [ ] x ={“car”,”bike”,”scooty”};


RESULT::car {array index starts from 0 count}

Change an Array Element

If you want to change the element of the array,refer the index number of the array.FITA JAVA Course


 string[ ] x={“car”,”bike”,”scooty”};



RESULT:: Instead of car..train will add

Array Length

Using this function we can calculate the number of elements inside the array.FITA JAVA Training Chennai


string[ ] x={‘train”,”bike”,”scooty”};



Using loop in Array

We can use the loop for the array to get the elements from the array and we can know how many times the loop should run

To be strong in java FITA the Best JAVA Training in Chennai


string[ ]  x = {“train”,”bike”,”scooty”};

for(int i=0; i<x.length;i++)







Multidimensional Arrays

If an array contains one or more arrays is called multidimensional array. To create a two-dimensional array add each array to itself of curly braces.

To explore more in java FITA Java classes in chennai


int[ ][ ] x={{1,2,3},{5,6,7}};

X is an array with two arrays with its elements

To access the elements of the X array, set the two indexes:

One for array and one for the elements inside that array.

If you need to explore more in java FITA Java Training


int [ ][ ] x={{1,2,3},{5,6,7}};

int y=x[1][2];



We can also use for loop inside the for loop to access the elements of a two-dimensional.FITA core Java training in chennai


int[ ][ ] x={{1,2,3},{5,6,7}};

for(int i=0;i<x.length;++i)

{for(int j=0;j<x[i].lemgth;++j)



Modifier Type

Modifiers are the keywords that can be added to those definitions, which are intended to be changed for their meanings. Java is a language that has a wide range of modifiers, inclusive of the following –

  • Java Access modifiers
  • Non Access Modifiers

For making use of a modifier, keyword is included in the definition of a class, variable, or method. Java Training in Chennai will be of great scope for you.

Access Control Modifiers

Java has number of access modifiers in order to set access levels for various classes, variables, methods and constructors. There are four access levels-

  • Those are visible to package, the default. No modifiers are required.
  • Visible to the class alone (private).
  • Visible to package and all the subclasses (protected).
  • Visible to the entire world (public).

Character Class

We come across many situations where need of objects is done instead of primitive data types. In order to achieve this, Java gives wrapper class Character for the primitive data type char.

The Character class normally wraps value of all the primitive type char into object. Thus, any object of the type Character can consists of single field whose type is char. Java Course in Chennai is the best course for professionals who are looking for domain change.

All the fields, constructors, and methods of the class Character that are specified by Unicode Data file and is a part of Unicode Character Database, which is maintained by Unicode Consortium.

Java in generic makes use of UTF-16 encoding method in order to represent the various char arrays in the String or String Buffer.

Escape Sequences

When any character is preceded by a backslash it is referred as an escape sequence and has specific meaning to compiler. FITA is ranked as the best institute for Java Course in Chennai.

String Class

With the help of various methods, it is simple to perform operations on string for instance trimming, replacing, converting, comparing, concatenating.

It is considered as a powerful concept as everything is considered as a string, while the submission is done any form in window, web based or mobile based application.

Creating Strings

Whenever there is a presence of string literal in the code, the compiler enables in the creation of a String object with its value in this case for instance, “Hello world!’.

It is possible to create String objects by deploying any new keyword along with a constructor. The String class consists of 11 constructors that enable the user to provide the initial value for the string with the use of different sources like an array of characters.

String Length

Methods used in order to obtain information regarding an object is referred as accessor method, which can be used with strings is the length() method that returns number of characters present in the string object.

Date and Time

Java is a proficient language that provides the Date class accessible in java.util package, and this encapsulates the current date and time.

Getting Current Date and Time

This is a simple method in order to get current date and time. You can make use of simple Date object with the use of toString() method in order to print the current date and time

Sleeping for a While

The user can sleep for any duration of time from one millisecond to the lifetime of the computer, which is an added advantage.

GregorianCalendar Class

This is a definite implementation of a Calendar class, which implements normal Gregorian calendar.

The getInstance( ) method of this Calendar returns a GregorianCalendar boot up with the current date along with time in default local and time zone. It defines both AD and BC fields, which represent two eras defined by Gregorian calendar.

Regular Expression

Regular Expression also known as Java Regex is an API used to define a pattern for initiating the search or manipulation of strings. This is a special sequence of characters, which aids the user to match other strings or sets of strings with the usage of a specialized syntax held in any pattern.

Its usage is widely done for defining the constraint on strings like password and email validation. After gaining knowledge in Java regex, it will be simple for you to test regular expressions by deploying Java Regex Tester Tool.

A java.util.regex package is provided by Java in order to match the pattern with regular expressions, which is similar to Pearl programming language. This package consists of three classes:

Pattern Class − This provides no public constructors. In order to create a pattern, user must invoke its public static compile() methods. It is compiled version of a regular expression.

Matcher Class − It is the engine that interprets the pattern and also performs public constructors. The user can obtain a Matcher object by just invoking the matcher() method on a Pattern object.

This implements the MatchResult interface.  The different methods available in the Matcher Class are:

  1. Index methods
  2. Study methods
  3. Replacement methods
  • PatternSyntaxException − This is an unchecked exception, which indicates the syntax error in a regular expression pattern.

Capturing Groups

Capturing groups are a way to treat multiple characters as a single unit. They are created by placing the characters to be grouped inside a set of parentheses. For example, the regular expression (dog) creates a single group containing the letters “d”, “o”, and “g”.

Java – Methods

It is a collection of statements, which are grouped together in order to perform an operation. When the user call the System.out.println() method,  the system executes several statements for displaying a message on console.

A method is nothing but a block of code that only runs when it is called by the user.

The user can pass data, called as parameters, into a method.

Methods are deployed to perform specific actions, called as functions.

Creating Method

A method is needed to be declared within a class. Moreover, it is defined with name of method, being followed by parantheses ().

Method Calling

For the deployment of a method, it is indeed necessary to be called. This can be done in two different ways: method returns a value or returning nothing.

In order to call a method in Java, user needs to write the method’s name succeeded by two parantheses () and a semicolon;

The process of method calling can be done with ease. When a program invokes any method, the control of the program gets transferred to the called method, which in turn  returns control to the caller in two conditions, when −

  • it reaches the method ending closing brace.
  • the return statement is executed.

Method Parameters

It is possible for the information to be passed to functions as a parameter that are specified after method name, within the parentheses. The user can also add as many parameters as per th necessity by just separating them with a comma.

The Void keyword

The void keyword enables the user to create methods that do not return a value.

Method Overloading

When a class consists of two or more methods by same name but various parameters, it is referred as method overloading, which is different from overriding. In the method of overriding, a method has same method name, type, number of parameters.

Passing Parameters by Value                               

While working concealed by calling process, an argument is to be passed. And this should be in same order as their corresponding parameters present in the method specification. Parameters can be passed either by value or reference.

Passing the parameters by Value stands for calling a method with a parameter.

Using Command-Line Argument

At times the user may determine to pass few information into a program when during the execution. This is done just by passing command-line arguments to main( ).

A command-line argument is information that directly proceeds the program’s name on command line when it is run. In order to access the command-line arguments within a Java program can be done with ease.

The finalize () Method

It is likely to define a method that is to be called before an object’s final destruction by garbage collector. And this  method is referred as finalize( ), that can be used in order to ensure that an object terminates perfectly.

In order to add a finalizer to any class, the user simply defines the finalize( ) method. Within the finalize( ) method, user will specify actions that are to be performed before the destruction of an object.

Files and I/O

The package contains nearly every class you might ever need to perform input and output (I/O) in Java. All these streams represent an input source and an output destination. The stream in the package supports many data such as primitives, object, localized characters, etc.

Java input and output process every input and generates the output based on the given input. Java makes  use of stream  in order to perform the input and output operation. Package consists the classes that are needed for the input and output operation. Stream is a series of data. There are three streams that are created automatically in Java which are as follows:

  1. This stands for the standard input stream and gives the data to the user’s program. Generally, a keyboard is used as standard input stream.
  2. System.out: It stands for the standard output stream in order to output the data generated by the user’s program and in generic monitor is used for standard output stream.
  3. System.err: It stands for the standard error stream and is used in order to get output the error data generated by user’s program.


A stream can be defined as a sequence of data. There are two kinds of Streams −

  • InPutStream − The InputStream is used to read data from a source.
  • OutPutStream − The OutputStream is used for writing data to a destination.

Java provides strong but flexible support for I/O related to files and networks but this tutorial covers very basic functionality related to streams and I/O. We will see the most commonly used examples one by one −

Byte Streams

  • Java byte streams are used to perform input and output of 8-bit bytes. Though there are many classes related to byte streams but the most frequently used classes are, FileInputStream and FileOutputStream.

Character Streams

Java Byte streams are used to perform input and output of 8-bit bytes, whereas Java Character streams are used to perform input and output for 16-bit unicode. Though there are many classes related to character streams but the most frequently used classes are, FileReader and FileWriter. Though internally FileReader uses FileInputStream and FileWriter uses FileOutputStream but here the major difference is that FileReader reads two bytes at a time and FileWriter writes two bytes at a time.

Standard Streams

All the programming languages provide support for standard I/O where the user’s program can take input from a keyboard and then produce an output on the computer screen. If you are aware of C or C++ programming languages, then you must be aware of three standard devices STDIN, STDOUT and STDERR. Similarly, Java provides the following three standard streams −

  • Standard Input − This is used to feed the data to user’s program and usually a keyboard is used as standard input stream and represented as in.
  • Standard Output − This is used to output the data produced by the user’s program and usually a computer screen is used for standard output stream and represented as out.
  • Standard Error − This is used to output the error data produced by the user’s program and usually a computer screen is used for standard error stream and represented as err.

Reading and Writing Files

As described earlier, a stream can be defined as a sequence of data. The InputStream is used to read data from a source and the OutputStream is used for writing data to a destination.

Tip for becoming a good Java programmer

Java is the considered as the basic programming language for many applications around the world. In addition, it is also the easiest language that can be learnt in order to enter the IT sector. When object oriented programming is considered the first thing that strikes our mind is Java that makes the way with respect to cross platform programming along with the application development.

Java Training in Chennai will be of great scope for you. Its popularity is due to the effortless path in order to perform multiple tasks related to programming. Java has been of complete utilization by the experts in the field. And for becoming an efficient developer in Java there are certain tips that will be useful for you.

Strong foundation in the basics

Whatever may be the course you are learning having a thorough knowledge in basics is considered to be very important. As there is no point of getting a doubt in sentence formation when you are not thorough of the alphabets. Its human nature to learn many things and forget the basics. Thus, it leads to the stumbling of developers during the creation of critical programs in Java programming as well.

Execute the gained knowledge

It is usual of children watching TV or listening music while studying these days, which leads to a shorter span of memory. Similarly, developers who just learn the concepts at one go and do not execute them will experience some sort of issue during the execution of any new program. Thus, we offer hands-on experience for almost all the topics in the class.

Figure out the code and algorithm

For any language it is indeed necessary to understand the code before its execution. Thus, start actualizing the need for each and every code you are using in the program right from the beginning, which in turn will build-up your confidence while writing complex programs. It is been witnessed that even experts who have years of experience split the whole program into smaller portions in order to solve them.

Memory allocation

This point has been mentioned for the developers who are changing their domain from C or C++ to Java. As the former language doesn’t consists of this feature. For further information related to Java do enroll yourself into our Java Classes in Chennai.

DevOps tools knowledge

Tools knowledge will be of great use during the execution of programs that are complicated. Thus, get the through knowledge of it from the experts from industry.

Create only useful objects

It is to be kept in mind that whatever object you create it must be useful as they are memory consumers along with the speed. As creation of any object is incomplete until memory allocation is completed. Thus, it will be better if you cross-check the object requirements prior to its creation.

Interface better than Abstract class

Multiple inheritance is absent in Java make sure you remember this throughout your career as this may have set-back in your life. When compared with the Abstract class, interface allows the user in having numerous methods in order to work.

Standard library added advantage

Java has blurred many languages that came into existence before it. This is due to the set of standard library which is present in abundance. These library methods makes the work of developer simpler in an organized manner. Moreover, the accomplishment of tasks is presented in a simplified manner.

Primitive classes prefer over Wrapper class

Wrapper class is of great service and primitive class are comparatively slower in nature as they only have the value whereas the former is able to store information. As wrapper class consist of object value whereas primitive class wont dish out the expected results.

Deal with Strings

Object-oriented programming categorizes string as class that affects both memory and speed of any system. Hence, you must be aware of the usage of string in Java. Get the in-depth knowledge in Java from experts by joining our Java Course in Chennai.

Learn Java 8

Even though its been almost 5 years since its launch still its usage has not been reduced due to its one line code feature such as lambdas and stream API. The launch of Java 9, 10, 11 didn’t affect much. In addition, Java 12which is expected to be launched in the month of March this year is much expected by developers for the latest features.

JVM’s internals

If becoming an expert in Java is your aim, then JVM internals is something which is to be shed light on. If you are well versed with this, then high-performance and robustness will be very easy for you. Thus, join our Java Training in Chennai for the enhancement of your career.

Design patterns

It will be helpful for you if designing patterns are a known part regarding Java course. With the knowledge of design you will be able to incorporate them into your code as per the requirement. Thus, be a step ahead from others by joining our Java Classes in Chennai.
