Answer 1

If the same code works in your friends computer, but not in yours, the problem is in your computer.

But dont give up try a few things before you decide to uninstall windows:

1- Make sure it does not work even if you use methods like repaint(), update or revalidate()

2- At this point there has to be some issue related to compatibility.

-Try updating windows

-Also update to the latest java version

3- Keep searching for your answer here is another question with a similar problem Java applications with Windows 7 - are there compatibility concerns?

4- Maybe the reason is windows 7. I have some college from college that are had similar issues in a programming subject in their laptops with windows 7(64bit). Some of them now use XP and others use Vista, and they don't have those kind of problems.

Good luck!
