Consider playing the Clip on another thread, as shown below. Once the
clip is initialized, it's easy to play repeatedly. A Swing Timer may be
convenient, as it's action is called on the event dispatch thread, on
which you have prudently constructed your GUI.
As an aside, watch your indents and line wrap. Also, don't try to put
the entire question in the title.

@John B. Matthews....Thanks bro...it works now. :)
What if I want the ball colours to change and also I want the size and
the speed to be like a menu?
