Question

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

Allow the code breaker to attempt guessing the secret code.

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

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

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

If the color is not correct no pegs are used

Red pegs are presented first, then the white pegs

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.

Codebreaker class

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

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

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

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

Output to the console the selected color

Add the color to the member variable codebreakerAttempt

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

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

Update method getCodebreakerAttempt() to call method consoleAttempt()

Codemaker class

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

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

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

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

If true, then red pegs should equal 4

If true, then white pegs should equal 0

If true, increment the red peg counter

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

If true, then increment the white pegs counter

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

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

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

Red is always first, then white!

Use an enhanced for loop to output to the console the codemaerker’s response

Game class

Call method play()

Instantiate an instance of class ArrayList specified as using class Color, set equal to calling method getCodebreakerAttempt() in class Codebreaker

Call method checkAttemptedCode() in class Codemaker, passing the local variable from step a. as an argument

Instantiate an instance of class ArrayList specified as using class Color, set equal to calling method getCodemakerResponse () in class Codemaker

Use an enhanced for loop to output to the console the codemaker’s response for each codebreaker’s attempt

Codebreaker class

Add private method consoleAttempt() that will allow for backend testing of the logic, it shall do the following:

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

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

Prompt the user to enter their guess, my implementation was as follows:

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

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

Loop until the user enters four valid colors with no duplicatesInstantiate an instance of class String set equal to Scanner’s method next()Evaluate the user’s input (Hint: recommend using either String method .toUpperCase() or .toLowerCase() to alleviate issues with case sensitivity)If the entered color matches one of the eight valid colors of the game, do the following:

Output to the console the selected color

Add the color to the member variable codebreakerAttempt

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

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

Update method getCodebreakerAttempt() to call method consoleAttempt()

Codemaker class

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

Implement method checkAttemptedCode() to do the following:

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

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

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

Check if the codebreaker’s guess is exactly equal to the codemaker’s attempt (Hint: class ArrayList has a handy method .equals())

If true, then red pegs should equal 4

If true, then white pegs should equal 0

If item d. fails, then determine which pegs are the correct color in the correct position or the correct color in the wrong positionLoop through the max pegs as defined in our Constants.java classCheck 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

If true, increment the red peg counter

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

Use an enhanced for loop using the codebreaker’s attempt as the collection objectCheck if the secret code ArrayList contains the current element of the codebreaker’s attempt (Hint: class ArrayList has a handy method .contains())Loop through the max pegs as defined in our Constants.java classCheck 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

If true, then increment the white pegs counter

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

Evaluate the red and white peg counters to populate the codemaker’s response

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

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

Red is always first, then white!

Use an enhanced for loop to output to the console the codemaerker’s response
