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?

[Roedy Green]

Here is the code I use for making sound. Use it with a SwingTimer or
Timer to schedule future sounds.

Capitalism has spurred the competition that makes CPUs faster and
faster each year, but the focus on money makes software manufacturers
do some peculiar things like deliberately leaving bugs and deficiencies
in the software so they can soak the customers for upgrades later.
Whether software is easy to use, or never loses data, when the company
has a near monopoly, is almost irrelevant to profits, and therefore
ignored. The manufacturer focuses on cheap gimicks like dancing paper
clips to dazzle naive first-time buyers. The needs of existing
experienced users are almost irrelevant. I see software rental as the
best remedy.

Just make your changes in the actionPerformed() method, before calling
repaint(). For menus, it's never too soon to learn about Action:

See also this the Model View Controller example:

I don't know how to connect the color to make it change the ball...any
help???
