Project 5
due Tuesday 3/9/04 3/23/04

Specification:

Step 1)
Create a class called PairOfDice, composed of two six-sided Die objects. (see chapter 4 for Die.java)

Step 2)
Create a driver class called BoxCars with a main method that rolls a PairOfDice 1000 times and counts the number of "box cars" (double sixes) that occur. This important step will allow you to test your new class before having to use it in a complex application. You must fully test PairOfDice.java using BoxCars.java.

Step 3)
Using the PairOfDice class, write a class to play a game called Pig. The rules for Pig are listed below. Keep in mind that your program must be as robust as possible. You must fully test this application under the assumption that PairOfDice.java functions correctly.

• In this game, the computer competes against the user. On each turn, the current player (either the user or the computer) rolls the dice and accumulates points.
• The goal is to reach one hundred (100) points before your oppenent does.
• If, on any turn, a player rolls a 1 on either die, all points accumulated for that round are forfeited and control is returned to the other player.
• If, on any turn, a player rolls two ones, all points accumulated in the game so far are forfeited and control is returned to the other player.
• The player may voluntarily turn over the dice after each sucessful roll. Therefore, the player must decide either to relinquish control of the dice, and possibly allow the other player to win, or to roll again (be a pig) and risk losing points.
• Implement the computer player such that it always reliquishes the dice when it has earned 20 or more points in any given round.

Notes)
For this project you must write separate Analyses, Data Requirements, Algorithms, and Test Plans for each class. The one exception is BoxCars.java. You do not need a Test Plan for BoxCars.java because it is the test vehicle for the PairOfDice class. However, you must still write an Analysis, Data Requirements and an Algorithm for the BoxCars class.
