Exiting full screen exclusive mode in Java AWT

We’ve been using Java AWT and Swing and needed full screen exclusive mode. (Not using JavaFX at the moment – but will be transitioning soon.)

This tutorial provides a nice way to enter full screen mode:

One problem that I faced was getting out of full screen mode after setting a window/JFrame as full screen.

The solution turns out to be simple:

myDevice.setFullScreenWindow(null);
