Your definition of "not used" is too vague. There are gauranteed to be applications running on any given system 100% of the time it's running. Could you narrow that down at all? – CollinD Apr 27 '17 at 05:20

The Process class allows you to run commands for windows/any OS from java below is snippet
Process proc = runtime.exec("shutdown -s");
System.exit(0);
Place the above code in your logic and rest how you want that to invoke depends on your logic the way you want.
Note : Here I am guessing by system you mean your OS. if you mean just application then just System.exit(0); would suffice.
EDIT :
As asked by OP to check the idle time, I think you need to implement event listeners mostly mouse and keyboard. Below are some helpful links to which will help you implement it in your program:
Java mouse motion anywhere on screen
How can I listen for key presses (within Java Swing) across all components?
Approach for above is have a timer just when you record an event from keyboard or mouse reset the timer else shutdown.

LOL After a short delay I can tell you that this does indeed work from windows as well. – Scary Wombat Apr 27 '17 at 06:04
