Is there any way by which I can change the screen resolution in Java. I mean to say that I need to change the resolution of windows desktop to 640 x 480 to 800 x 600 on the click of a button. Is it possible?

Well, there is full screen exclusive mode. This lets you change the screen resolution, but I think only for the actual Java application itself. I don't think it allows you to change the resolution persistently for other applications. In any case, that's where I'd start looking.

I think Ernest is right. That means that you'll have to use JNI to do this. The ChangeDisplaySettings and ChangeDisplaySettingsEx Windows system functions are probably what you need for Windows. No idea for Linux.
