Hey guys :) My professor is letting me do this extra credit assignment. I have already made a source code for a Monty Hall Problem without GUI, but this one calls for a code with GUI, and I have no idea how to do it. Please help me!!! It isn't due until 12/14/09 so I have some time, but I wanted to get it done so any help I can get I would greatly appreciate!!! :) Here is the question:

The “Monty Hall Problem” takes its name from the classic television game show “Letʼs

Make a Deal,” which was hosted by Monty Hall. During the show, a contestant is shown

three doors, labeled 1, 2, and 3. One of the doors hides a prize (like a brand new sports

car); the remaining doors each conceal a (live) goat. The host (Monty Hall) is the only

one who initially knows what is behind which door.

After the contestant selects one of the three doors, Monty opens one of the other doors

to reveal a goat. The prize is still located behind one of the unselected doors, and the

other door still conceals a goat. The contestant now has the option of sticking with his

original choice or switching to the other door. Monty then opens the selected door to

reveal what the contestant has ultimately won.

This problem is a favorite in probability and statistics classes. Should the contestant

switch doors when he has the chance? Should he stay with his original choice? Does it

make a difference? How often does the contestant leave with the sports car, and how

often with a goat?

Write a simple GUI program that simulates this game. Use a random number (1, 2, or 3)

to select the winning door (see the end of this document for a brief description of Javaʼs

Random class). The GUI should display three buttons, one for each door. The user can

click on a button to select that door. After the user chooses a door, the program should

disable one of the other door buttons and change its label to reﬂect that it hid a goat

(Hint: use JButtonʼs setEnabled() and setText() methods for this part). The user

can then click on one of the two remaining buttons to open that door, at which point

those door buttons are relabeled with their contents.

Your GUI should also include a “reset” button that will allow the player to try again.

Include JLabels that show how many times the game has been played, how many

times the contestant switched doors, how many times the player won the car, and how

many times the player won a goat. Note that JLabel also has a setText() method.
