Taking Screenshots in Java

I found this blog about taking screenshots in Java. This is something I had never thought about doing, the thing that I find interesting about this article is the KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusedWindow()
this line of code I had never seen before but I think I'm going to look deeper into it because it maybe able to solve some problems at work.
