Java Assignment

The goal is to simulate the foundation of the components of the game MasterMind by creating a Codemaker, Codebreaker, and the Game; this includes:

1. Allow the code breaker to attempt guessing the secret code.

2. Have the code maker respond to the code breaker’s attempt.

a. If the correct color is in the correct position, the code maker’s response should include a red peg

b. If the correct color is in the wrong position, the code maker’s response should include a white peg

c. If the color is not correct no pegs are used

d. Red pegs are presented first, then the white pegs

3. Limit the number of attempts to 10 guesses, if the code breaker guesses the code, they win the game, if the code breaker does not guess the code within 10 guesses, they lose the game.

Constants package

Constants class

core package

Codebreaker class

a. Remove previous data stored in member variable codebreakerAttempt (Hint: class ArrayList has a handy method . removeAll())

b. Instantiate an instance of class Scanner to take input from the console

i. System.out.println(" Enter your colors in left to right order " +

ii. "Use BLUE, BLACK, ORANGE, WHITE, YELLOW, RED, GREEN, PINK:");

d. Loop until the user enters four valid colors with no duplicates

i. Instantiate an instance of class String set equal to Scanner’s method next()

1. Evaluate the user’s input (Hint: recommend using either String method .toUpperCase() or .toLowerCase() to alleviate issues with case sensitivity)

A. If the entered color matches one of the eight valid colors of the game, do the following:

I. Output to the console the selected color

II. Add the color to the member variable codebreakerAttempt

B. If the size of the codebreakerAttempt is less than the max pegs specified in our Constants.java file then add a prompt to enter for the user their next color

e. Using an enhanced for loop output to the console the codebreaker’s attempt

2. Update method getCodebreakerAttempt() to call method consoleAttempt()

Codemaker class

1. Update method signature checkAttemptedCode () to match the modified method signature in interface ICodemaker

a. Create local variables to store the number of red and white pegs scored by the codebreaker

b. Create a local variable to store which pegs have been evaluated of the codebreaker’s guess

c. Create a local variable to convert the secret code Set member variable to an ArrayList object

i. If true, then red pegs should equal 4

ii. If true, then white pegs should equal 0

e. If item d. fails, then determine which pegs are the correct color in the correct position or the correct color in the wrong position

i. Loop through the max pegs as defined in our Constants.java class

1. Check if a correct color is in the correct position by comparing index to index of the two ArrayLists representing the secret code and the codebreaker’s guess

A. If true, increment the red peg counter

B. Add the codebreaker’s guess at this index to the Set that stores the evaluated pegs

2. Use an enhanced for loop using the codebreaker’s attempt as the collection object

A. Check if the secret code ArrayList contains the current element of the codebreaker’s attempt (Hint: class ArrayList has a handy method .contains())

i. Loop through the max pegs as defined in our Constants.java class

1. Check if the secret code ArrayList is NOT equal to the codebreaker’s attempt at the specific index AND the secret code ArrayList contains the codebreaker’s attempt at the specific index AND the pegs evaluated Set does NOT include the current codebreaker’s attempt at the specific index

A. If true, then increment the white pegs counter

B. Add the current index of the codebreaker’s attempt to the ArrayList that stores the evaluated pegs

i. For each red peg, add to the member variable codemakerResponse Color.RED

ii. For each white peg, add to the member variable codemakerResponse Color.WHITE
