Out of Lab Program 3

Craps Simulation

Due Tuesday March 19, at the start of lab

Assignment

Suppose that you are considering heading to Las Vegas over Spring Break to play Craps. To decide what your odds of winning are, you are going to write a Java program. The program should simulate 100,000 games of Craps and then print out the results.

Rules of Craps

A game of Craps is played with two six-sided dice. The dice are rolled. If you roll a 2, 3, or 12 on the first roll, you lose. If you roll a 7 or 11 on the first roll, you win. Otherwise, keep rolling until you either get the same number as your first roll (you win in this case) or you get a 7 (you lose in this case).

Desired Output

Craps Simulation
----------------

100000 games:

45000 wins
55000 losses

Probability of winning: 45.00%

Note: 45% is not the real probability of winning.

Required Classes

To solve this problem, you should use a Driver class and a Craps class. One of the methods in the Craps class should be a boolean method called simulateOneGame. This method should return true if the game is won and false if the game is lost. Hint: you might want to take advantage of the Math.random() method in order to simulate a die roll.

What to Submit

A printout of Driver.java and Craps.java.
A diskette with your Java code on it. On Tuesday, March 19th, your program will be tested as part of the in lab.

Grading

The program simulates Craps correctly.
The output format matches the output format above.
The program is well commented.
The program uses meaningful names.
The program uses indentation and white space appropriately.
The program uses classes appropriately.

Special Notes

You may work with one other person on this assignment. However, that person must be in the same lab section as yourself. If you work with a partner, just hand in one printout and one diskette with both of your names on it.
