Preferably using StdDraw class in java, draw a bouncing balls in a box animation where all the balls are black except for one. The one ball that isn't black can be red, and whenever the red ball hits the black ball, the black ball disappears. Have this animation continue until only the red ball remains. (You can define the number of balls via command-line argument such as java BouncingBalls x where x is the number of balls you have chosen). The balls don't have to collide with each other but obviously have to bounce around the edges of the box.
