This is a demo of the MultiBallWorld as an applet It generates some colored balls in in a frame and lets them bounce around for a few seconds. From the book OOP with Java, chapter 5 - by Timothy Budd Extensions from original version as in Budd's book Added file MultiBallApplet.java as a front end applet so that the program can be run as an applet. Increased the size of the balls. Color of balls chosen randomly. Original Ball class broken up into Ball and MovableBall classes. Notes: The game plays in its own frame, not on the browser screen. To get the applet to run again, click the reload or refresh button while holding down the shift key (Netscape or MS Internet Explorer).
