Compiling Error?

I can't compile my code...I think I know how to fix it, but I don't know the exact details.


Here's what I think
You go to Control Panel, Then System, Advanced, Then Enviroment Variables.

After that I have no idea...Any Suggestions?

Can you explain what your problem is?

If you know the location of the javac command, you can compile your program using the full path to the compiler:
C:\Java\jdk1.6\bin\javac.exe YOURPROGRAM.java

To tell the OS where to look for a command, you need to add the path to the folder containing the command to the PATH environment variable.

Add JAVA_HOME in Enviroment variables and also add java_home\bin in path variable in system variables

For example
Variable Name = Path
Varaiable value = %SystemRoot%\system32;C:\Java\jdk1.6\bin
