After adding the ball to the frame, you have forgotten to set the bounds for the ball.

Using a null layout is always a bad idea. Why do you want to do that?
The frame's content pane defaults to BorderLayout If you do not set the layout to null, your Ball panel will occupy the whole frame (default: BorderLayout.CENTER)
