What is Java ?

Java is an Object Oriented Programming (OOP) language developed primarily by James Gosling and his colleagues at Sun Micro Systems. This language was initially called Oak.
In 1991, the Sun Micro Systems developed this complete language as a part of research work to develop software for consumer electronics. It was developed as a full-fledged programming language in which one can accomplish the same sort of tasks and solve similar problems like other languages like C++, BASIC etc. The main significance of Java is that it is platform independent, it has the capability to be moved easily from one system to another.

A Java program can be written in two ways :-

  1. Java Application : A java program developed by the user.
  2. Java Applet : Java programs that can be downloaded from the internet and can be run on user's system.

Basic features of the Java language :-

  1. It is an object oriented language.
  2. It is both compiled and interpreted.
  3. Its programs are platform independent.
  4. It is multithreaded language.
  5. It does not require any preprosser (#) or inclusion of header files.
