Programming Language is the language that only the computer understands. The computer has many programming languages. One of which is Java Programming Language.

In this post, we will learn what is Java? What is the use of java? (What is Java in Hindi), how does Java reduce it? History of Java, Types of Java Applications, Java Version, and how to learn Java Language? We will understand all these in the first place.

It is used to build Desktop and Mobile applications.

Now let's understand more deeply about JAVA.

What is java?

What is java in Hindi

Java is a General Purpose Programming Language. We save the coded file from a Java Programming Language in .java extension.

Java is used for the development of software and applications. Java is also called High-Level Programming Language.

A code written with a popular programming language can run in any other platform. It is based on C and C ++ syntax.

All the codes written in it are in English. So that anyone can easily understand the codes written in it. That is why it has been included in the High-Level Language.

Java is also based on the concept of C ++ or Oops. Fundamentals of Oops are used in Java.

The Java programming language is not designed for any particular hardware or operating system. Therefore programs created on java can be run on any system.

What is the use of java?

What is java used for, features of java

There are many fields where Java is used.

It is used by the programmer to develop programs. If compared to other programming languages like C, C ++, it is easier to develop programs from java.

Java programming language can be used to create everything from web applications to desktop and mobile apps. This is followed by Java Security and regular updates in it.

This Programming Language has only one purpose. Whatever code is written in it, it should be run on all computers. For example, the code written in Windows is also run in Mac OS.

Now we know in detail where Java is used.

Web application

Java is used to develop web applications.

Being easy and secure to use Java language, it is easy to develop applications related to important fields like government, healthcare, insurance, education, and defense department.

Desktop application

The desktop application can be easily developed by it. Different types of APIs (Application program interface) such as Windowing Toolkit (AWT), Swing, and JavaFX are used to create them.

Mobile Application

Java is considered an official programming language for mobile application development. An application that is designed to be installed and used in a mobile device is called a mobile application.

Today, most mobile or smartphones are Android OS based, and Android development is done by Java only. The Java Micro Edition Framework is used to build applications.

Standalone Application

Standalone Application is also called as desktop applications or Windows-based applications.

These are the same software that we often install on our computer or laptop.

Enterprise Application

Enterprise Application is a software system platform. Which is used in a big environment like Government, Corporate, Business, Schools, etc?

In Java, EJB is used to build enterprise applications.

Is more secure and powerful than other languages.

Java enterprise edition is a very good platform that provides API and Runtime environment, for scripting and runtime enterprise software.

Scientific Application

Most developers prefer Java language to develop a scientific application. The main reason for this is that Java is more secure, portable, and maintainable.

How does Java work?

How to work java,

Java has more advance and simple features.

Java is also more secure than other programming languages.

It is very important to follow rules like Syntax to write any program from Java language.

Java Virtual Machine or Abstract Computing Machine is used to run Java code. Now let's understand this.

Java Virtual Machine: -

JVM's full form is Java Virtual Machine. Through which the Java program is run. JVM runs the program using Java Interpreter.

The Java program is already run by the Java Virtual Machine installed on the computer. By which the code of Java is run on each computer.

Java code running on one platform does not need to be recompiled to run on another platform.

Platform Independent: -

Java is called Platform Independent Language because its code can be run on Java Operating System like Windows, Linux, Mac, Android.

But the code of a program like Platform Dependent cannot be run on every OS.

History of java

Java History, History of Java in Hindi

Java is a High-Level Programming Language. Which was started in 1995 by James Gosling, developer of Sun Microsystems and his team?

James Gosling is considered the main developer of Java. He had only one principle behind making this language. "write once run anywhere". This means the language will be written only once and it will be used everywhere. This means it is compatible with all OS platforms.

James Gosling first named the program greentalk. Then it was changed to Oak. This name was already registered by Oak Technology, so it was changed again to java.

Types of Java Applications

The Java Programming Language is listed in 3 departments.

JAVA 2 Micro or Mobile Edition (J2ME)

JAVA 2 Standard Edition (J2SE)

JAVA 2 Enterprise Edition (J2EE)

J2ME: - JAVA 2 Micro or Mobile Edition is used to develop mobile applications using the wireless access protocol.

J2SE: - JAVA 2 Standard Edition is used to develop such client-side applications. Which the consumer can see.

J2EE: - JAVA 2 Enterprise Edition is used to develop server-side applications.

J2EE is a Platform Independent Program. With the help of which it is possible to create a Web-Based Enterprise Application.

Java Version History

Application to write Java Program

Java Editors are required to write a Java program.

For this, you can use Notepad ++. This is such an application in which you can write code very easily. It is also easy to find the error and find the Missing Bracket.

Apart from this, you can use many more applications. Such as - Netbeans, Eclipse, etc.

Java is a language for which each version has some traces. And in this case, the more you know about it, the less.

You know in this post what is Java? What is the use of java? (What is Java in Hindi), how does Java reduce it? History of Java, types of Java applications, Java Version, and applications for writing Java programs.
