This is one of  four major individual assignments that you are required to complete in this class. You MUST design and code this project on your own. You can ask for debugging help, particularly from the tutors, TA or instructor, but this project is to be your own work. The project relies on knowledge and skills that you will develop in Recitation Laboratories 1, 2,  and 3. If you are having trouble with these recitations after your in-class session, please be sure that you come to the lab at another time and sit down with a tutor.

Hand-in Requirements:

• Hard-copy source for: SlotMachine.java and SlotMachineMain.java
• Hard-copy of the program output

Overview:

You will develop a SlotMachine class to represent the slot machine and a SlotMachineMain to test the SlotMachine and play the games.

The SlotMachine Class

• The data fields:
  • Three String values:  fruit1, fruit2, and fruit3 containing the choices that were randomly picked
  • A boolean value myResult indicating whether the game was won or lost.
  • Three int counters: myGamesWon, myGamesLost, myTotalGames representing the number of games won, the number of games lost, and the total number of games played.
• The constructor:
• The three String values are initialized by calling the private helper method getFruit
• The counters are initialized to 0.
• myResult is initialized to false
• The usual accessor methods:
• The getResult, getGamesWon, getGamesLost, and getGamesPlayed methods do the expected things.
• The getPercentWon method calculates the percentage won and returns this value as a double
• The toString method returns the games won, games lost, games played, percentage of games won. You should use the getPercentInstance located in the NumberFormat class for this. (See p. 89 of the textbook for an example.)
• The modifier method:
• The pull() method makes three calls to getFruit (one for each of the three choices) and stores the returning value in the appropriate variables.  It then decides if the game was won or lost using the specifications described above. The appropriate counters should be updated.  Call the private helper method displayResults described below.
• The private helper methods:
• The getFruit method uses the random method in the Math class to pick a number between 0 and 3 inclusive.  It will then use a switch statement to determine which choice was made and return it as a String.
• The displayResults method prints the three choices and if the game was won or lost.  This can be done by testing the boolean value myResult.

The SlotMachineMain Class for testing:

• Instantiate a SlotMachine and name it slot1
• Play this machine 5 times by calling the pull method
• Print the results of the 5 games by calling the toString method
• Instantiate another SlotMachine and name it slot2
• Play this machine 7 times by calling the pull method
• Print the results of the 7 games by calling the toString method
• Decide which machine you should keep playing by calling getPercentWon for each machine and printing the appropriate message. If a tie results tell the player to play either machine.
