Is there any difference between the two. I was reading an article ( http://www.javalobby.org/java/forums/t17933 ) about that you should always use

System.exit(0);

Currently I use 

JFrame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

The article says that even for a Java Swing Application you should add a listener WindowAdapter and and call System.exit() inside its method windowClosing(WindowEvent e).

Is there any difference? Is one method better then the other?

java swing jframe exit
