Assignment Scope       

For this 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:

Set up constants, which are used for clarity, safety and consistency throughout a project.

Establish the method signatures (i.e. methods that must be implemented in the classes) for the interfaces ICodemaker, ICodebreaker, and IGame.

Establish the member variables for the classes to replicate the real game, write custom constructors, generate getters/setters for the member variables, instantiate instances of classes, write a simple method to randomly generate the secret code in the Codemaker class.

To accomplish this, write the follow source code:

Create constants using “public static final”

Using Java API classes Arrays, ArrayList, Color, HashSet, Random and Set

Update the interfaces to include method signatures

Updating the classes to include

Member variables

Getters/setters for member variables

Create an instance of Java API class Color and set it equal to the color stored at the index of the Constants.codeColors ArrayList by calling the get() method in class ArrayList passing the int from step i. above as an argument

Add the selected color to the Set member variable by calling method .add in class Set passing the Color object from step ii. above as and argument
