Java is the object oriented, similar to C++ high-level programming language and architecture neutral developed by Sun Microsystems. Java was originally called OAK. Object Oriented meaning the capability to reuse code. Secondly, it is platform independent i.e. we don't have to develop separate applications for different platforms. It is possible to develop a single application which can run on multiple platforms like Windows, UNIX, and Macintosh systems. Java was designed for hand-held devices and set-top boxes.

Source code (files with a .java extension) of the Java program is converted to Byte code (files with a .class extension) by the java Compiler which in turn is converted to machine code by java Interpreter.Java interpreters and runtime environments, known as Java Virtual Machines (VMs). Bytecode can also be converted directly into machine language instructions by a just-in-time compiler (JIT).

Java can be used to create two types of prgs. Those are Applications and Applets. An application is a prg.that runs on the user’s computers under the operating system. An Applet is a small window based prg.that runs on HTML page using a java enabled web browser like internet Explorer, Netscape Navigator or an Applet Viewer.
