    Operation
    If the user chooses to roll the dice, the application rolls two six-sided dice, displays the results of each, and asks if the user wants to roll again.
    Specifications
    Create a class named Die to store the data about each die. This class should contain these constructors and methods:
    public Die() // default to a six-sided die
    public Die(int sides) // allow a variable number of sides
    public void roll()
    public int getValue()

    Create a class named PairOfDice to store two dice. This class should contain two instance variables of the Die type, an instance variable that holds the sum of the two dice, and these constructors and methods:
    public PairOfDice() // default to six-sided dice
    public PairOfDice(int sides) // allow a variable number of sides
    public void roll()
    public int getValue1() // get value of die1
    public int getValue2() // get value of die2
    public int getSum() // get the sum of both dice
    You can use the random method of the Math class to generate a random number from 1 to the number of sides on a die like this:
    int value = (int) (Math.random() * sides);
    Create a class named DiceRollerApp that uses the PairOfDice class to roll the dice. This class should display special messages for craps (sum of both dice is 7), snake eyes (double 1s), and box cars (double 6s). For this application, assume that two six-sided dice are used.
    Create a class named Validator that contains static methods that can be used to validate the data in this application.

    Moved from Introduction section.

    Start by creating the classes listed in the assignment with the methods that each is supposed to have. Leave the insides of the methods empty for now except for those that return a value just return a constant value to make the compiler happy. For example:
    public int getValue1() {  // get value of die1
      return 1;  // hardcoded number for now
    }
    If you don't understand my answer, don't ignore it, ask a question.
