How to uninstall Java(TM) SE Development Kit 6 Update 24, Java(TM) 6 Update 22 from my PC?

I installed Java(TM) SE Development Kit 6 Update 24, Java(TM) 6 Update 22 in my PC. But by mistake I deleted all the files regarding them including the executable file. Now when i went to Control Panel >> Add or Remove programs, and tried to uninstall them system throws an error "Fatal Error while install" as it could not configure the files. Pls help me uninstall them by suggesting me other way round.
