What is Java?

Do you know how to learn What is Java? and Java Programming Language with it. In today’s post, we are going to tell you about java.

In today’s time, the Demand for Programming Language is very high. If I tell you an interesting thing, your hoses will fly away. In recent times, Java Code is used in more than 3000000 Electronic Device. From this, you can guess how popular this Programming Language has become.

All the Smart Phones you are still using and Electronic Devices like AC, Oven, Smart TV, Digital Fridege. It is used in all of them. If you Android If you want to learn Programming, then learning Java is very important. So let’s see What is Java?

What is Java?

Java is a General Purpose Programming Language. These are called Software and used for Application Development. java is also a High Level Programming Language.


It was started by Sun-micro system in

Sun 1995 It is one of the major developer in James Gosling. It is also Platform Independent Language. You can run the code written in any platform or os.

All the codes written in it are in English. Anyone can easily understand the codes written by it. That is why it has been included in the High Level Language. It follows the concept of Oops. Fundamental of C ++ Language has been used in it.

To write a program in it, some rules are followed. To whom Syntax is sown. Writing a program without syntax generates error. Like whenever you write Hindi or English. So if you do not follow the rules of Grammers in it, then it goes wrong, though it is very important to follow Syntax in it.

What is the use of Java

This Computer Programming Language has only one purpose. Whatever code is written in it, it should be run in all computers. Whether it is both machine or any OS (Windows or Mac).


Code written in C ++ like

is never the same Execute in another machine. Code written in Windows never runs in Mac OS but it does not in java.

It is used to create web based programming and mobile application, software. All the operating systems of Android like Kitkat, Lolipop, Oreo have all been developed from this programming language.

How Java Program Code Runs or Executes

This language uses an Abstract Computing Machine to run the code, named Java Virtual Machine .

Java Virtual Machine

Its short form is JVM. It is a Virtual Computer that runs all Java programs. When a Program is written. The same is called the Source Code.

Byte Code Generate is done by compiling the same source code with the help of Java Compiler. JVM is used to execute this Byte Code. The JAVA Interpreter inside the JVM runs the same program.

Platform Independent

By its name, you must have understood that it does not depend on the platform. Platform here means OS. Such as Windows,Linux, Mac, Android. When we write programs or create a software, they all run on the OS platform.

What was the purpose of making JAVA – Use of Java in Hindi

You will know that all the Programming languages ​​are and were before. They follow all the procedural structure. After this, the Obeject Oriented concept came to my mind that in today’s time, Obeject Oriented changed the entire Programming Industry. This programming language also follows the same concept.

You must be thinking that although there are so many computer languages ​​already, what is special about this? In recent times, you must know how much Demand of Internet Applications are in it. Whether it is Online Video / image editing, whether to convert something online like Word to PDF, ZIP, RAR FILE Creating is all due to this.

Berief History of Java in Hindi

Its history is very fun, so it is very important to know this. It was married to the Green Team. Members of the Java team were called the Green Team.

The only objective of this team was to create an AC language which can be programmed in electronics devices like Set-top Boxes, Television. At that time it was an Advance Concept.

James Gosling

James Gosling is one of the main developer of JAVA. In recent times, Java is used for Internet Programming, Mobile Devices, Games, E-Business solutions.

Why was it named Oak

Oak is also known as the Symbol of Strength. Oak is the National Tree of Weasten Countries (USA, France, Germany, Romania). The name Oak was changed to Java in 1995.

Why was it named JAVA

When the Green Team was choosing a Jut Hok language name. All those team members gave some name suggestions such as Dynamic, Revolutionary, Silk, Jiot, DNA.

He wanted to have a name that would represent his technology. Any name that is Revolutionary, Dynamic, Lively, Cool, Unique. According to James Gosling, at the end there were two suggestions of names, one is Silk and the other was JAVA. The Green Team found the name JAVA to be quite unique; finally it was named.

Java was the name of an island in Indonasia. Where Coffee Produce first took place. It was developed in Sun MicroSystem. It is currently a part of Oracle Corporation. JDK 1.0 was released in January 1996.

History of Java Version

Over time, different version of JAVA released their information is given below.

JDK Alpha and Beta (1995)J2SE 1.3 (8 May, 2000)
JDK 1.0 (23 Jan 1996)J2SE 1.4 (6 Feb, 2002)
