What is Java

Java is a platform independent object oriented programming language, developed by Sun MicroSystem in the year 1995. Java was originally called OAK and was designed to handle devices and set-top boxes. Sun change the name OAK to JAVA and modified the language of the world wide web. Java source code files(files with .java extension) are compiled into a BYTECODE(file with a .class extension) which can then be executed by a java interpreter.

Compiled java code can run on most computer computers because java interpreters and runtime environment known as JVM exist for most operating system like UNIX, Macintosh, and Windows.

Features of Java

1-Simple
There are various features that makes the java as a simple programming language, because Java is easy to learn and developed because its mostly concepts are similar to C and C++. It is very easy to learn Java who have knowledge of object oriented programming concepts.

2-Secure
When we convert the Code from One Machine to Another the First Check the Code either it is Effected by the Virus or not or it Checks the Safety of the Code if code contains the Virus then it will never Executed that code on to the Machine.

3-Portable
Java is portable language because you can run java program from one platform to another because any restriction

4-Object Oriented
We Know that is purely OOP Language that is all the Code of the java Language is Written into the classes and Objects So For This feature java is Most Popular Language because it also Supports Code Reusability, Maintainability etc.

5-Robust
The Code of java is Robust because it first checks the reliability of the code before Execution of the program when we trying to convert the higher data type into the lower then it checks the demotion of the code the It will warns a user to not to do this so it is called as robust

6-Multithreaded
Unlike most other programming languages, Java provides built-in support for multithreaded programming. A multithreaded program contains two or more parts that can run concurrently. Each part of such a program is called a thread, and each thread defines a separate path of execution. Thus, multithreading is a specialized form of multitasking

7-Distributed
Java is Distributed Language Means because the program of java is compiled onto one machine can be easily transferred to machine and Executes them on another machine because facility of Bytes Codes
