Try installing Java IDE and write your codes and compile... like Netbeans.....

In your command prompt write java -version and do you get any messages.

Open a command prompt, navigate to the bin directory and just type javac. If you get a screen full of options then there's nothing wrong with the install. Also, try using the full path to the javac.exe in your
compile command.

thanks....i tried as u said but it showing that "java is not not recognized as internal or external command operable program or a batch file"......

Hmmm.... For my knowledge that's all I can think about. Or try to update Java Version or downgrade it. Or reinstall java.
Are you Sri Lankan or Indian?

I think that i have to unistall it again

Oh! I am Sri Lankan. Most Sri Lankan names similar to you. And Sri Lankans have big relationship with India.
Yeah try reinstalling it.
