2. Using the Die class defined in this chapter, write a class called PairOfDice, composed of two Die objects. Include methods to set and get the individual die values, a method to roll the dice, and a method that returns the current sum of the two die values. Create a driver class called RollingDice2 to instantiate and use a PairOfDice object. (30 Marks) [hint: you need to have three classes, Die, PairOfDice and RollingDice2, the PairOfDice will use Die class and RollingDice2 which is the driver class of your program will use PairOfDice class]
