public class LetsMakeADealApplet

extends Applet

implements ImageCanvasEventHandler

This is a simple applet that lets someone play the classic three door game from Let's Make a Deal. A prize is hidden behind one door. The player chooses one by clicking on it. Another door is then revealed to hold a booby prize. The player can then choose to keep either what's behind the door she selected or the other unopened door.

This applet keeps track of the win & loss statistics for the two strategies of play (stay with selected door/switch to other door). It also has autoplay capability, so you can quickly see how the resulting statistics.

There are three parameters that can be set in the APPLET tag:

• doors - number of doors (at least 3)
• autoplayGames - number of games played when player clicks the autoplay button
• resetValue - maximum number of games played before statistics are reset
