Class DemoController

java.lang.Object
  frog.demo.DemoController

public class DemoController
extends Object

The DemoController manages all Sprites and sound in the game. After the initial DemoGame window has been set up, it uses DemoController to run the game. After DemoController has been created, DemoGame's only job will be to ensure that the requested FPS is maintained and that special keyboard events are handled (such as mute).
