I want to write a program that performs certain action when certain keys are pressed. The only way I know how to do this requires the java program to opened (or focused at least). How can I keep it running in the background so that it keeps listening regardless of which program/window I currently have open?

EDIT: I'm using Windows

Which OS is this targeting? – Bathsheba Nov 25 '15 at 10:44
Sorry forgot to mention this, I'm using Windows. – youssefmaged Nov 25 '15 at 10:45
The problem here is that you have to intercept the keystrokes before the OS diverts them to the appropriate application's message pump. Normally it's the application with the focus that receives it. I'd be surprised if anyone here tells you how to do this since doing that is the foundation of so much malware. – Bathsheba Nov 25 '15 at 10:50

You can't, not using (only) Java, anyway. – Stultuske Nov 25 '15 at 10:58

What other way can I do it? – youssefmaged Nov 25 '15 at 11:01
