JAVA PROGRAMMING

Source file names:

Mastermind.java (contains main())

MastermindPuzzle.java

EasyMastermindPuzzle.java

HardMastermindPuzzle.java

Winnable.java

If doing part 2, also include:

MastermindGUI.java

MastermindFrame.java

Mastermind is a game where the player tries to figure out a pattern based on a series of clues. 4 different colored pegs (R for red, B for blue, G for green, W for white, P for purple, and Y for yellow) are chosen and hidden from the player. Then the user picks 4 pegs and guesses at the pattern. The computer will tell the user how many pegs are the correct color (hint, hint you may want to reuse them in the next guess). The computer will also tell the user how many of the correctly colored pegs are also in the correct position. The user has up to 10 attempts to figure out the pattern.

This project should be done in 2 parts. The first part is a text based version of the game. Completing this part is worth up to 90%. If you complete the first part, then you may add a GUI to it for the last 10%. If you do the GUI portion, you still need to submit the text-based version. I will first test the text-based version. I will only look at the GUI version if your text-based version works.

Now even if you dont write the GUI portion, I should be able to use your Mastermind classes and pair it with someones GUI classes and have it work the same. So, here is something you can use for main() in the text-based version:

On a side note, I realize that this is not the only way to accomplish the game. But when working in a team, public methods are often negotiated ahead of time and you must conform. Consider us in a team and I wrote the text-based main().

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

MastermindPuzzle mp;

int easyHard;

int puzzleNum;

System.out.print("1=easy, 2=hard? ");

easyHard = input.nextInt();

System.out.println();

System.out.print("Puzzle num? ");

puzzleNum = input.nextInt();

System.out.println();

if (easyHard == 1)

{

mp = new EasyMastermindPuzzle();

}

else

{

mp = new HardMastermindPuzzle();

}

mp.startGame(puzzleNum);

char[] guess = new char[mp.getNumPieces()];

while (mp.stillPlaying())

{

System.out.print("Guess? ");

for (int i = 0; i < guess.length; i++)

{

guess[i] = (input.next()).charAt(0);

}

System.out.println();

mp.makeGuess(guess);

System.out.printf("%20d %d --> ", mp.getLastCorrectColorCount(), mp.getLastCorrectPositionCount());

for (int i = 0; i < guess.length; i++)

{

System.out.print(guess[i]);

System.out.print(' ');

}

System.out.println();

}

if (mp.won())

{

System.out.println("Congratulations!");

}

else

{

System.out.println("Sorry, you lost");

}

}

As a result of main() above here are a few notes:

Mastermind class

Only needs to include main() above

MastermindPuzzle class

All instance variables should be private (not public or protected)

Should be abstract

Needs to implement Winnable interface

Need at least the default constructor

getNumPieces needs to return an integer with the number of pegs in a puzzle (currently 4 use constants!)

chooseSolution should accept an integer that is the puzzle to choose and it must be abstract

startGame should accept an integer that is the puzzle to choose (1 through 3 or -1 for a random puzzle)

You must call chooseSolution in this method

I recommend that this method also reset your other variables that remember the state of the current game

makeGuess accepts a character array with the letters to check

I recommend that this method increase the number of guesses made, and set 2 instance variables that indicate the number of correctly colored pegs and the number in the correct position

This is the longest, most complicated method in the class

getLastCorrectColorCount needs to return the number of pegs that are the correct color in the last guess

getLastCorrectPositionCount needs to return the number of pegs that are in the correct position in the last guess

You may add extra methods to help yourself

EasyMastermindPuzzle class

This should be a subclass of MastermindPuzzle

This class ONLY needs constructor(s) and chooseSolutionchooseSolution should do the following:

If the parameter is 1, set the puzzle to R, G, B, W

If the parameter is 2, set the puzzle to P, R, W, Y

If the parameter is 3, set the puzzle to W, B, Y, P

If the parameter is -1, set the puzzle to random colors (4 out of R, G, B, W, Y, P)

HardMastermindPuzzle class

This should be a subclass of MastermindPuzzle

This class ONLY needs constructor(s) and chooseSolutionchooseSolution should do the following:

If the parameter is 1, set the puzzle to R, G, B, R

If the parameter is 2, set the puzzle to P, R, P, Y

If the parameter is 3, set the puzzle to W, W, Y, P

If the parameter is -1, set the puzzle to random colors (4 out of R, G, B, W, Y, P) with at least 1 duplicate color within in the puzzle

Winnable interface

This should have 3 methods each returns a boolean: won, lost, stillPlaying

Sample Run #1: (the highlighted text is what the user types)

1=easy, 2=hard? 1

Puzzle num? 1

Guess? R G B Y

3 3 --> R G B Y

Guess? R G B W

4 4 --> R G B W

Congratulations!

Sample Run #2: (the highlighted text is what the user types)

1=easy, 2=hard? 2

Puzzle num? 1

Guess? R Y B B

2 2 --> R Y B B

Guess? R R G R

3 2 --> R R G R

Guess? R G B R

4 4 --> R G B R

Congratulations!

Sample Run #3: (the highlighted text is what the user types)

1=easy, 2=hard? 1

Puzzle num? 1

Guess? P Y G B

2 0 --> P Y G B

Guess? R G B Y

3 3 --> R G B Y

Guess? G R P Y

2 0 --> G R P Y

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Guess? B G R W

4 2 --> B G R W

Sorry, you lost

Part 2: (The GUI part)

If you choose to do the GUI version, then you need to write 2 additional classes:

MasterminGUI

This class contains main() it only needs to create MastermindFrame and display it

MastermindFrame

This class contains all of the controls and the event handlers

You should only need a constructor and 2 event handlers (I made mine anonymous)

The constructor should be creating the controls, initializing them, and adding them to the Frame

Use radio buttons for easy or hard choice

Use a combo box for the puzzle num (random,1 ,2, or 3)

Use a button for start and guess

Use 4 combo boxes for the user to enter their next guess (each box should have the choices R, G, B, W, Y, P)

Use a text area for the results (what you would print after each guess)

The 2 event handlers (one for the start button and one for the guess button) should generally be pieces of main. Youll have to replace the prompting code with getting values from the controls on the Frame.

Heres what it should look like when you start the program (The title bar of the Frame should show Mastermind it does on mine, but is not showing in the screenshot):
