To start external program with Runtime.getRuntime().exec(...) in foreground

I have a JFrame with JTable. When I click a row in JTable another GUI process is started with Runtime.getRuntime().exec(...), e.g. "notepad.exe". However that new window appears not in foreground, but below my swing window. How to start a new process window and bring it to top?

The new process is independent of the spawning process. You have to use whatever constructs it has to bring it to the top.

And what constructs I can use to control another process window in Java? JNI or anything else?

...check the command line options of the process you are spawning.
