center property of Ball is a misnomer

The center appears to actually be the top-left corner of the Ball component's bounds.

• Translate image drawn such that center actually represents the center of the Ball.

Question 2

• Design an implement a "bouncing-balls" program, using the Swing (or some other) GUI platform.
• It should start with an empty frame.
• Each time the user clicks on the frame, a ball appears and starts moving in a random direction at a constant (and also random) speed.
• When the ball hits the edge of the frame, it should bounce accordingly (assume perfectly elastic collisions, and ignore collisions between balls).
• Each ball should run as a separate thread in the application.
• Design your Ball class so that it extends the JComponent class (for Swing implementations) to take advantage of its rendering capabilities.
