It looks like you are running the method from the event dispatch thread.  
This is what would happen if you call the method from an event listener 
attached to a button, menu item, or other UI component.

Painting also happens on the event dispatch thread, so your UI will not 
be painted until some time after you return from the event listener.

What you need to do is to run your method in a separate thread.  The 
following link provides information using multiple threads with Swing:

The following gives more general information about threads:

These are both part of "The Java Tutorial", which is a very good place to 
learn about many Java features.  You may want to start at the top of the
