With in decade JAVA has taken the computing world by storm, Today Java is the first choice of internet programming.

Java has no major differences from other languages but it has a collection of features that are not found together in the standard definition of any other language.

The embedded programs are needed for Electronics machines like Refigerators, Washing Machines, and Microwave Ovens. Such a language must be platform independent; therefore developer of java ensured that java be platform independent. Similarly the language needed for web programming must be platform independent, therefore, java tend to be right candidate for web based applications.

Sun Microsystems offered Java2 platform in three different flavors: J2SE (Java2 Standard Edition) is mainly for building Small and Medium based application. J2EE (Java2 Enterprise Edition) is mainly for building Medium and large scale applications. J2ME (Java2 Micro Edition) is mainly for developing Mobile devices based applications.

Java is pure object-oriented programming language. If you aware of any programming languages like C/C++, then learning java is not at all difficult.

The central concept of object-oriented programming is the object, which is a kind of module containing data and subroutines. The point-of-view in OOP is that an object is a kind of self-sufficient entity that has an internal state (the data it contains) and that can respond to messages (calls to its subroutines).
