Question for anyone who know's swing, given this class

import javax.swing.JOptionPane ;
class foo
{
 public static void main(String [] args)
 {
  int btn = JOptionPane.showConfirmDialog(null, 
   "hello world!", 
   "foo", 
   JOptionPane.OK_CANCEL_OPTION,
   JOptionPane.QUESTION_MESSAGE ) ;
  
  System.out.println("button was " + btn ) ;
 }
}

how do i make it exit once I've clicked one of the buttons on the dialog ? update found this thread on exiting swing apps, If this is true, then it seems like a lame ass design descision to me.
