 (defined in <code>WindowConstants</code>):
 Automatically hide the frame after
 invoking any registered <code>WindowListener</code>
 objects.

 <li><code>DISPOSE_ON_CLOSE</code>
 (defined in <code>WindowConstants</code>):
 Automatically hide and dispose the 
 frame after invoking any registered <code>WindowListener</code>
 objects.

 <li><code>EXIT_ON_CLOSE</code>
 (defined in <code>JFrame</code>):
 Exit the application using the <code>System</code> <code>exit</code> method.
 Use this only in applications.
