Entire-Screen Capture

This program captures the entire screen and saves it as an image file. The process is done through the use of the Robot class. The setState(JFrame.ICONIFIED) method minimizes the frame before the process begins and the setState(JFrame.NORMAL) method restores the frame when the process ends.
