Any body please can please help me, how to center a JFrame on Mac. OS X?

I have tried:

this.setLocationRelativeto(null);

this.setLocationRelativeto(this);
this.setLocationRelativeto(getRootPane());

..and 

    final Toolkit toolkit = Toolkit.getDefaultToolkit();
    final Dimension screenSize = toolkit.getScreenSize();
    final int x = (screenSize.width - this.getWidth()) / 2;
    final int y = (screenSize.height - this.getHeight()) / 2;
    this.setLocation(x, y);

None of the above worked, my frame is still at the bottom and hidden behind the Mac dock.

Note that neither of those answers involves centering the GUI on screen. There are better alternatives. – Andrew Thompson Mar 30 '12 at 04:12

Location should be set after you packed your frame (wich calculates size of the frame). And after that it should be made visible (it is hidden by default otherwize).

 pack();
 setLocationRelativeTo(null);
 setVisible(true);
