Thank you! It works..But why do we need to do it.. ? ?

yes.
Thank You.

javac is an executable command which comes as part of the jdk package.

You will be executing javac command from your command prompt which is part of Windows. Windows doesn't have any idea as where to find the javac.exe or simply javac executable from. By setting the path or environment variable you are telling windows the location of javac.exe it can access to execute it.

Hope this helped...

Cheers...

Thank you..
Now its Working.
Can you please explain the reason behind it?

U can set the path in another way also.
Go to my computers -> c drive -> programme files -> java -> jdk 1.6 ->
bin now copy the path that is in the address bar.Now on the desktop right click on My computer icon and select properties .Here select the Advanced tab -> Environment Variable -> in system variables select path then click on edit -> now in the edit system variable box put a ';' at the end and paste the copied path and click on OK button.Your path is set now .Try this
