The method of "exit(int)" from "System" class is used to close the program .

In the program that i wrote there's a window that opens with "Frame" class, in this window there's a button by pushing which another window is supposed to open.

Now I have trouble making my program close the second window without closing the first one. I tried to use exit(int) but it closes the whole thing. Does anyone have any idea how I should do it?

I'd appreciate it if the solution you give is in 'system' class.

Thanks very much.
