How to install and configure java(JDK) environment to develop programs?

Before going to start installation of java(JDK) ,I will suggest you that please check your system configuration and match that ,would your system is fulfilling the minimum requirements required to run java.I am pasting the link of ORACLE website were the minimum and maximum requirements are  available,I am not writing them here because these requirements change time to time.So here is the link:-


Installation Guide and System requirements on Oracle website:-
http://docs.oracle.com/javase/7/docs/webnotes/install/

Windows Requirements:-

So if your system fulfill the  hardware and software requirements then you can go to following steps of installation:-

1. Download the java(JDK) form the Oracle website as per your Operating system,link of Oracle website for JDK is :-http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html    .This link when pasted the JDK7 was latest one development kit.
   
2. Here I am using Windows 64 bit OS machine so I am downloading the Windows x64.After downloading the JDK you will get one file with extension .EXE(because I am using Windows OS,you have to download as per your OS),so double click on this setup file:-
