1.Java SE:
We need a Java Platform first, so we will download it from java.sun.com
The latest update is 6u26. Choose your Operating System and also make sure you download the correct xx-bit architecture. Ex: x86 or x64.

2. Eclipse:
Now we need a Compiler to execute and run our Java programs.
There are two most popular compilers, Netbeans and Eclipse. I prefer Eclipse.
I would recommend you to use Eclipse IDE for Java EE Developers. Again make sure you choose the correct xx-bit architecture.

Installing and Running Guide:
1. Extract it and run the eclipse file(as Administrator).

Great guide! now one question, does java programs need dependency or no? if they don't ill start java right away! :biggrin:

If you are talking about software dependency, yes you need both those softwares stated in OP.

If you are talking about other languages, you might need to learn C++, but you can start it with Java itself, its not that much based on any other language that you need to learn that first. But learning C++ will make it easy to understand variables, operators, other functions, but if you are fast learner, you can learn it easily without C++.

var Iknow = "i already know variable, oporators and functions in C, C++, Python, C#, Delphi and PHP no need for starting again :biggrin:";
printf(Iknow);
}
