Hi? I need to know how can I compile and run a JAVA program in Window seven.. I was trying but I am unable to make it.. - Firstly i installed the JDK 5 in my system.. - I copied the path for the executable files (for the bin directory), and I pasted it in the environment variables paths - I created the simple java program. I used javac to compile, and java to run. The file name and program class name were the same, There were no error on compilig, but execution gave no output.. Any cruel??
