and whenever i type javac it shows the list as it should, also I can execute my programs from eclipse. I didn't tried from cmd. Anyone having idea what this is?

Edit: it worked randomly after i repeatedly executed the command but it comes back.

It seems like you have a corrupted installation ("possible disk/network problem."), please reinstall your JRE/JDK and report back if that solved the issue.
