Java windows command

Question

I am trying to compile some java code on Windows 7 pc, I have installed java JDK and I am trying to use the javac command in cmd but I get output saying that

'javac' is not recognized as an internal or external command, operable program or batch file.

What do I have to do to enable compiler in cmd or is it possible to do in Windows?

Either add the path where your `javac` executable resides to your `%PATH%` environment or use the absolute path to `javac` for executing it. — Dominik Sandjaja, Feb 15 '13 at 12:54

1)Go to properties by right click on icon Computer , then navigate to Advanced System Settings.

2)Click Environment Variables.

3)Click on New , set Variable name as path and Variable path as the path of java jdk installation directory which could be something like this -

C:\Program Files\Java\jdk1.6.0_23\bin;

where C:** is the drive where JDK is installed and **Program Files\java is the directory where it resides.

look out for semi-colon(;) at the last.

4)Click ok

5)Restart cmd and run javac , it should work now.

Look for Screenshots here for more help.

Did it work..?? , i dont know why it didnt happened , may be Oracle guys are lazy enough to code that , there was a time when JAVA used be under SUN , and it was shining , but now Oracle has ruined the rep of JAVA :/ – anshulkatta Feb 15 '13 at 13:38
