public class MMGame

extends java.lang.Object

Class MMGame provides the evaluation engine for a game of MasterMind. The MMGame object will internally store a hidden code of a given length and made up of an alphabet of a given size. It will accept guesses in the form of strings. If the guess is invalid it will not be processed. Otherwise, it will be accepted. Once a guess is validated, the MMGame object will report on the number of complete matches and the number of partial matches. The object also records the number of valid guesses, and stops accepting guesses once the game is over (a perfect guess is accepted).

Constructor Summary

MMGame()
Default constructor to create game where solution is 4 digits long and each digit can have 6 possible values (0-5).

MMGame(int n, int k)
Constructor to create game with specified solution length n and number of possible values k for each digit.

Method Summary

int	getNumGuesses() Access the number of user guesses so far this game.
int	getNumHidden() Access the length of the hidden solution (n).
int	getNumTypes() Access the size of the solution alphabet (k).
boolean	guess(java.lang.String s) Stores the specified string as the user's current guess, provided it is a valid guess -- correct length and no invalid characters.
boolean	isGameOver() Find out if game is over (correct solution) or not.
int	numComplete() Given a valid guess, will compute and return the number of characters in the guess that exactly match corresponding characters in the solution.
int	numPartial() Given a valid guess, will compute and return the number of characters in the guess that match characters in the solution but are in the wrong position.

Constructor Detail

MMGame

public MMGame(int n,
              int k)

Constructor to create game with specified solution length n and number of possible values k for each digit.

Parameters:

n - the length of the solution, where n > 2

k - the number of possible values for each digit, 0 thru k-1, where k > 4.

MMGame

public MMGame()

Default constructor to create game where solution is 4 digits long and each digit can have 6 possible values (0-5).

Method Detail

guess

public boolean guess(java.lang.String s)

Stores the specified string as the user's current guess, provided it is a valid guess -- correct length and no invalid characters.

Parameters:

s - a String containing the user's guess.

Returns:

true if guess is valid and false otherwise.

numComplete

public int numComplete()

Given a valid guess, will compute and return the number of characters in the guess that exactly match corresponding characters in the solution.

Returns:

number of correct characters in correct position.

numPartial

public int numPartial()

Given a valid guess, will compute and return the number of characters in the guess that match characters in the solution but are in the wrong position.

Returns:

number of correct characters in incorrect position.

getNumHidden

public int getNumHidden()

Access the length of the hidden solution (n).

Returns:

length of solution

getNumTypes

public int getNumTypes()

Access the size of the solution alphabet (k).

Returns:

size of solution alphabet

isGameOver

public boolean isGameOver()

Find out if game is over (correct solution) or not.

Returns:

true if game is over and false otherwise

getNumGuesses

public int getNumGuesses()

Access the number of user guesses so far this game.

Returns:

number of user guesses
