CSC 211 -- LasVegas Project -- 100 Points

Note:   You must have three classes in your project:

1. The Craps class, described in this document,
   
2. The Die class, given shown at the link,
   
3. The Main class, discussed in the last section of this document.

1. Before starting a turn, a player places a bet of money between the minimum and maximum allowable bets (minBet and maxBet). This bet is deducted from the amount of chips.

2. A player starts a turn by rolling a pair of dice.
   • If the sum of the dice is 7 or 11, the player wins and the amount of chips is increased by the amount of the bet.

   • If the sum of the dice is 2, 3, or 12, the player loses the bet.

   • If the player rolls any other sum (4, 5, 6, 8, 9, or 10) this first roll is recorded, and the player keeps rolling.
     • If the first roll (called the point in casinos) occurs again before a sum of 7 occurs, the player wins and the amount of chips is increased by the amount of the bet.

     • If a sum of 7 occurs first, the player loses the bet.

The UML Diagram of the Craps Class

• Here is a UML diagram for the Craps and Die classes.

  

Meanings of Instance Variables

Method Specifications

• public Craps(int theMinBet, int theMaxBet)

  Constructor for the Craps class. Set minBet and maxBet to theMinBet and theMaxBet, respectively.

• public int getMinBet()

  Accessor method for the minBet instance variable.

• public int getMaxBet()

  Accessor method for the maxBet instance variable.

• public int getBet()

  Accessor method for the bet instance variable.

• public void setBet(int theBet)

  Mutator method for the bet instance variable. If the specified amount is between minBet and maxBet (inclusive), set bet to theBet. Otherwise, do not change bet. Deduct the amount of the bet from amount.

• public int getAmount()

  Accessor method for the amount instance variable.

• public void setAmount(int theAmount)

  Mutator method for the amount instance variable. If the specified amount is nonnegative, set amount to theAmount. If the specified amount is negative, do not change the amount.

• public boolean isAWin()

  Return the value of win.

• public void play()

  Complete a turn according to the Rules of Craps listed above. Update amount based on the amount of the bet and whether the turn wins or loses. Also record each of sum or each roll in the roll array. Here is some suggested pseudocode for the play method.

• public void printRolls()

  Print the values of the rolls of the previous turns from the saved values in rollArray.

• public String toString()

  Optional 5 points extra credit: write a toString method for the Craps class that you think makes sense.

Specifications for the Main Method

1. Create a Craps object by passing in the minBet and maxBet to the Craps constructor. Suggested values are 5 and 500.

2. Set the value of amount by using the corresponding mutator method.

3. Set the values of bet by using the corresponding mutator method.

4. Invoke the play method.

5. Get and print the value of win using the isAWin method.

6. Get and print the value of amount.

7. Invoke the method printRolls.

8. Repeat steps 3 through 7 to test two additional turns.
