Java Training In Bangalore

Prerequisites to learn Java Course

There are no prerequisites to learn the Java programming language. Except one needs to have some basic computer skills. Anyone who aspires to become a Developer can learn Java.

Application of Java

Java is a popular programming language and it is widely used among various domains at present. Below we have explained briefly where Java is being used for different purposes.

• Banking: Helps in dealing with transaction management.
• Retail: All the billing applications we see in the store and restaurant are written using Java.
• Information Technology: Java is designed for solving implementation dependencies.
• Android: Most of the applications are written using Java or Java API.
• Stock Market: Writing Algorithms in which the company should invest.
• Financial Services: They use Java for writing their Server-Side applications.
• Big Data: Hadoop MapReduce frameworks are written using Java.
• Scientific and Research Community: For dealing with enormous data.

Features of Java

• Simple
• Portable
• Object-Oriented
• Secured
• Dynamic
• Distributed
• Robust

Simple: Java has simplified the works of Developers by removing the complexities like pointers and operator overloading that we see in C++ or other programming languages.

Portable: Java is an independent platform that indicates any application that is written on one platform could be easily transferred to other platforms.

Object-Oriented: Every entity in Java is an object on which the actions are performed using these objects.

Secured: Every code in Java is converted to bytecode after the compilation process and it cannot be read by humans. Java enables us to develop tamper-free and virus free system applications.

Dynamic: Java can adapt to the evolving environment that supports dynamic memory allocation. Because of this memory wastage is reduced and performance application is increased.

Distributed: Java provides a feature that helps in creating distributed applications. Using the Remote Method Invocation (RMI), a program could invoke the method of other programs across a network and receive the output. We can access the files by calling the methods from any of the machines on the internet.

Robust: It has an excellent memory management system. Java helps in eliminating errors as they check the code during runtime and compile.

Java Editions

Java has multiple editions that are available today. Mentioned below are some of the important editions of Java.

Java Standard Edition (SE)

Java Standard Edition is also known as SE is a standard SDK. SDK is used in developing applications of the desktop.

Java Enterprise Edition (EE)

Java Enterprise Edition (EE) is mostly used for taking the complete business online. It caters to the data storage, web aspect, mobility aspect and develops the standalone applications. Enterprise Edition is an all-in-one solution that consists of multiple tiers. Different API’s are available within Java Development Kit. Those kit permits you to develop applications for different tiers that could be frontend, middleware, database, or mobility.

Java Micro Edition (ME)

They are designed specifically for mobile devices.

Standard Edition:

java.applet

This permits you to run small flash applications inside the browser. Applets are phased out as presently browsers do not permit us to have plug-ins installed. Instead, we opt for HTML5 for creating small apps or games that would run within the browser.

java.awt

java.awt is known as an abstract windows toolkit. This is the API that is used in developing Window based applications or GUI in Java. It is similar to the MS Office product that is a stand-alone product. Java Training in BTM at FITA Academy provides a holistic understanding of Java Concepts with market-relevant skills.

java.lang

It contains classes that are basic to designs of Java programming language. It is the core package or core API.

java.rmi

The expansion of RMI is Remote Method Invocation. They are the set of functions that provide a mechanism for creating distributed applications. One can have their code hosted on a server and they could access them by sending a request from the client.

java.sql

It is used for performing the Java Database operations. It is primarily used while connecting a database and firing the SQL queries.

Then we have java.sql which is used to perform java database operations while connecting to a database and firing SQL queries.

java.util

This package consists of the collection and other utility classes. A utility class is used for storing temporary memory and data, access date and time, iterating over data, and processing data before sending it to the database.

Enterprise Edition

javax.annotation

Its purpose is to simply associate information with the program element. Instead of writing many codes, Annotations brings the requirement down to write code and helps us in identifying the top codes.

javax.ejb

Enterprise JavaBeans package is used in improving the enterprise based applications and using reusable codes. It could be deployed on a remote server and multiple users for connecting it and using it.

javax.jms

Java Messaging Service is also called as JMS. This is a messaging standard that permits applications to create, receive, read, and send messages between each other. In case, if we want one Java application to communicate with other Java application, we should use the JMS API, so the information and messages are sent.

javax.persistence

It is the application programmer interface or the API specification. This describes the management of the relational data on applications using the Java platforms. Persistence here means data storage.

javax.servlet.http

They support the development of servlets. Servlets are the small Java programs that run on a web server. We can access them using an HTTP protocol. It provides a feature that we could send a request to the Java Program. Java Training in Marathahalli at FITA Academy provides a wide academic curriculum of the Java Course to the students along with blended learning.

javax.servlet.jsp

It is a scripting language that is used for creating dynamic content for web applications. Servlets are Java programs that are complied with already to create dynamic content. JSPs run slower compared to servlets because it takes time for converting and compiling the JSPs to Java servlets.

Micro Edition

Device Access API

Device Access API provides you a set of functions. It allows you to access the device or sensors so you could write effective programs.

System Configuration API

It permits you to access different system-level configurations on Android and specific OS that runs on the device.

OAuth2 API

This is an authorization framework that permits you to obtain limited access to user accounts like facebook, twitter, etc. We can use the login credentials by using the claims-based authentication.

JSON API

JavaScript Object Notation is also known as JSON. This API is used in sending and receiving data on the JavaScript object between server and client.

HTTP Client API

They are used in writing code for HTTP protocol. We can communicate along with your mobile app using this micro edition.

Security API

Security API provides access to sensitive resources while building applications from Java micro-framework.

Today, Java is used in almost every type of application, from mobile apps to enterprise systems where you can learn Java Training in Bangalore. If you want to get into web development, Java is a great choice. In addition to being free, it also offers a wide range of tools and libraries to help you build better websites.

Now let’s take a look at how Java can improve business operations.

Faster, more efficient workflows

You don’t have to wait for someone else’s approval before sending an email or making changes to a document. With the right tooling, you can make your workflow completely automated. For example, CRM (Customer Relationship Management) software allows salespeople to send out personalized emails to customers with all the latest information about them without having to go through an IT department.

Increased automation

Sending those important messages? You could automate your entire process using a message service like Amazon Simple Email Service learning from the Best Java Training Institutes in Bangalore. It will automatically route your emails based on content, time, and location, which means there will be no need for manual intervention. This lets you focus on other things.

Better security

If you’re building a payment system for your website, using Java technology gives you control over the user experience. For instance, you can create secure connections between your site and third-party services like PayPal. Without this kind of protection, hackers could potentially steal your customers data.

More features

With additional libraries and APIs, many applications can do much more than they ever would otherwise. Whether it is providing access to online storage, geolocation services, or connecting to social networks, these platforms can add tons of functionality to your app.

Better customer support

It might not seem like it, but poor customer service can really damage your reputation. To solve this problem, some companies use Java to give their support staff the power to check up on users remotely. For example, if a user experiences issues, an expert can diagnose and fix them instantly. Java Training Institutes in Bangalore will support you in gaining this knowledge.

Great new technologies

Since Java is so easy to pick up, lots of developers find themselves exploring newer, cooler tools. Recently, Google announced Flutter — another framework that runs on JavaScript and Android Studio. These powerful new technologies are opening up entirely new avenues for web designers and coders.

Stronger community

The best thing about Java is that it’s built on strong, open standards. As a result, it plays well with others, meaning you’ll have access to a larger pool of resources and knowledge when you need them from a Java Course in Bangalore.

Versatility

Java has always been highly flexible, with a simple syntax and a lot of different ways to accomplish the same task. You can get this from the expert Java Training in Bangalore.

However, its design isn’t perfect; as the language matures, more limitations are appearing. Thankfully, because Java is still one of the most popular languages in the world, you’ll always be able to find programmers who can step in to handle any bugs or missing pieces.

Less complexity

Many people are intimidated by programming languages. But when you learn Java from the Best Java Training Institutes in Bangalore, it quickly becomes easier to approach coding because it uses familiar concepts and conventions. You can jump right in and start creating functional code instead of needing to unlearn everything first.

Stability and maturity

When you think about it, developing with Java is almost guaranteed to be less frustrating than developing something in Python or C++. It’s mature and stable, which means it’s ready for production immediately.

No matter what your project goals are, choosing to develop with Java may provide benefits that you wouldn’t get from any other platform.

No IDE required

Unlike HTML, CSS, and Javascript, which require visual editing tools, Java doesn’t require anything special. That means you won’t need to invest in expensive development equipment just to write Java programs. The downside: You won’t be able to edit files visually.

Lots of great frameworks

From Twitter’s Bootstrap to Zend Framework 3, there’s plenty of useful open source Java-based software out there you can download for free. You don’t even have to know how to program to take advantage of all these preconfigured solutions.

Compatibility

Like I mentioned earlier, Java is compatible across multiple devices. So you can create a single set of source code that will work perfectly on both desktops and mobile phones.

High performance

Getting a Java Training in Bangalore you can create a Java program that starts working as soon as you compile it. That way, you don’t waste time waiting around while your computer finishes running through its entire compilation process. And once it does finish compiling, your app is ready to run.

Security

One last reason why using Java makes sense is security. Because of Java’s robustness, no data entered into your program can be altered without the user knowing about it.

This also protects against malicious activity, such as an infected file being sent over email.

If your business needs a quick boost, try some of the apps below to see if they could help solve your problems.

Video games

Of course we aren’t giving up on video gaming entirely! We’ve included this one simply because games can often run faster, look better, and function better than any website. Most game developers choose Java, so it has access to some amazing tools and resources.

The simplicity of JAVA programming?

The popularity of this platform stems from its ability to create cross-platform programs without having to worry about different programming languages or libraries. The main reason why it is widely accepted among programmers is due to its simplicity and power. Java is also known to support object-oriented programming (OOP) concepts.

Java is often referred to as “the J” because the letter “J” stands for java. This makes it easier to remember, especially when you have many lines of code written in Java.

What is OOP?

Object-Oriented Programming (OOP) is one of the most popular paradigms of computer science. In short, Object-Oriented Programming means that we can model real-world objects using classes and objects. Classes define what other objects do while objects represent those things.

This paradigm allows us to build complex applications easily and quickly. We can reuse existing objects and make changes at later stages. For example, let’s assume that we need to develop a web application where users will pay their bills online. If we use a non-object-oriented approach, we would have to start from scratch if we want to add new features to our application. On the other hand, if we implement our application using OOP principles, we can simply extend already available billing methods and add new ones as well.

Why Java is so Popular?

As mentioned earlier, Java is a very powerful programming language. It has all the necessary tools and facilities to allow developers to get started right away. Also, the syntax of Java is very simple, making it easy to learn. These reasons have made Java extremely popular among both beginners and experienced programmers alike.

Developers prefer Java over C++ because it is more reliable than C++. As compared to C++, Java is much safer to work with. There are no memory leaks, data race conditions and security flaws. Another reason why Java is preferred over C++ is that it is highly scalable.

Java supports multi-threading. Multi-threaded programming is the process of running several threads of execution simultaneously within the same program. Without multi-threading, your program might not function properly. However, Java offers multi-threading through the concept of thread pools. Thread pools are groups of threads that are managed by the operating system. They reduce the number of context switches between them. Threads in a pool share the resources of the CPU.

Java provides excellent performance and scalability. Unlike some other programming languages, Java does not require the user to explicitly manage memory. Instead, the garbage collector automatically handles the task of freeing unused memory. In addition, Java uses native data structures such as arrays instead of generic data types. Therefore, there is less overhead associated with these types.

The last but certainly not least reason why Java is so popular is that it is free! Free software exists in two forms: open source and closed source. Open-source software is freely distributed for anyone to study, modify and redistribute under certain terms and conditions. Closed source software is proprietary software that is sold to customers.

Open Source Software

Open source software refers to any type of software that is freely distributed and licensed. Many companies offer it to their customers. Some examples include MySQL, Apache Tomcat, Linux, etc.

Open source software is usually developed by individuals who feel passionate about creating something useful. They contribute their code to an open source project or community. The community then takes care of developing the project further.

A good example of this would be the GNU Project. GNU stands for “GNU is Not Unix”. What they do is create a completely different operating system called GNU/Linux. They release it under the GPL license which means that everyone can download it for free and keep it forever.

Closed Source Software

In contrast to open source software, closed source software refers to software that is proprietary. Companies often sell closed source software to its customers. Examples include Microsoft Office, Adobe Photoshop, Java Runtime Environment (JRE), Oracle Database and many more.

What Makes Java Different From Other Programming Languages?

Java is an object-oriented programming language. This means that every piece of information has an owner. For instance, a car has a driver, an engine, tires, etc. Each component has a particular purpose. When you want to change one part of the car you need to think of what will happen if you remove or add another component. You have to decide whether you should remove the engine or replace it with a new one.

This way of thinking makes programmers write programs in a modular fashion. Programs are divided into objects. Objects have attributes and methods. Methods are functions that operate on the attributes of the object. Attributes represent properties of the object. For instance, a person has a name, age, height and weight. The name attribute represents the first name, the age attribute represents the age, the height attribute represents the height and the weight attribute represents the weight. A method operates on one or more of these attributes. For instance, getName() returns the name of the person.

If you were asked to develop a program that adds up all the weights of people in the world, you could start by writing a class named Person. It has attributes that hold the names and ages of people. Then you could write a method named getWeights(). This method gets all the weights from all the people whose names are present in the list returned by getNames(). This is just one simple example of how objects work together in Java.

You will learn another important concept from Java Institutes in Bangalore is polymorphism. Polymorphism means that a single function can work on several types. One common example is when you call the print() function on a number object and a string object. In both cases, the same result is printed out.

The most important feature of Java compared to other languages is that a programmer does not need to worry about memory management. The garbage collector comes into play automatically. If there isn’t enough space left in the heap, the GC kicks in and frees some memory for you. There are also classes that make sure that the memory is freed as soon as possible. So even though Java doesn’t require manual memory management, it still does it for you.

Why Use Java?

There are many reasons why businesses use Java. Since it’s an object-oriented programming language, it allows developers to reuse code. They don’t have to reinvent the wheel because they can simply create a new object that contains the features they need. Object orientation also helps them avoid duplication. Because different parts of the program do different things, you won’t end up duplicating your efforts.

Java Institutes in Bangalore will teach you how a lot of companies prefer Java over C++ because it provides better security than C++. Java is written entirely in plain English so there aren’t any hidden bugs like buffer overflows. Also, the JVM uses stack protection so hackers cannot easily manipulate data stored on the heap. These two points explain why Java is used more frequently than C++.

Java is also faster than C++. This is because Java compiles down to native machine instructions whereas C++ requires you to compile at every level. As a result, Java apps run much faster than those written in C++. However, this advantage tends to be offset by the fact that Java needs more memory than C++.

Since Java was designed with portability in mind, it runs on almost every type of computer system. That said, if you want to run a Java app on a Windows PC, you’ll have to download special software called a virtual machine. Virtual machines allow you to run a program without actually having a copy of the operating system on which the program runs. You install the VM onto your hard drive and then use it to run the app.

Java is easy to learn but difficult to master. While Java is easier to understand than C++, it’s harder to debug than C++. Even experienced programmers struggle to find problems in their programs. But once you’ve mastered the basics from Java Training in Bangalore, you’ll love working with Java.

What Do I Need to Know Before Learning Java?

Before learning Java, you should know what you’re getting yourself into. To begin with, Java is an object-based programming language. This means that everything in the program exists as an object. For instance, if you needed to add numbers, you’d create a class named Add Numbers. This class would contain methods such as add(), subtract(), multiply(), divide(), etc. Now when you wanted to add 2 + 5, you could call the add() method from within another object. When you finish using the object, you’d just set it aside. It will be destroyed after its time has passed.

When you start writing Java applications learning from Java Course in Bangalore, you’ll notice that methods are very similar to functions. A function returns something while a method returns nothing. In addition, all objects inherit from a base class called Object. Every object has properties and methods. Properties store information about an object while methods perform actions on the object.

Java is an object-oriented language. This means that every object must have both a state and behavior. Objects can either exist or not exist. An object that exists may appear to do things. If an object doesn’t exist, it won’t do anything. All objects have a reference to a collection of other objects called a “class.” The class defines how the object behaves. Classes can have subclasses. Subclasses inherit the features of their ancestors. They can override inherited methods.

Java is one of the most popular languages around today with Best Java Training Institutes in Bangalore. Because of this, there are lots of great books available for beginners. One of these is Beginning Java: From Novice to Professional. It teaches you the fundamentals of Java in a fun way. Another good book is How to Think Like a Computer Scientist: Learning With Java and Python. This book explains basic concepts in computing, including algorithms and data structures, using Java.
