Explanation / Answer

public class RollingDice
{
   //-----------------------------------------------------------------
   // Creates two Die objects and rolls them several times.
   //-----------------------------------------------------------------
   public static void main (String[] args)
   {
       Die die1, die2; // instantiation of 2 Die objects
      int sum;

      // the point is that Die is a class written by authors of book,
      // not a standard class in a Java library

      die1 = new Die(); // constructor
      die2 = new Die();

      die1.roll(); // roll die1
      die2.roll();
      System.out.println ("Die One: " + die1 + ", Die Two: " + die2);

      die1.roll();
      die2.setFaceValue(4); // sets die2's face value
      System.out.println ("Die One: " + die1 + ", Die Two: " + die2);

      sum = die1.getFaceValue() + die2.getFaceValue(); // access face values
      System.out.println ("Sum: " + sum);

      sum = die1.roll() + die2.roll();
      System.out.println ("Die One: " + die1 + ", Die Two: " + die2);
      System.out.println ("New sum: " + sum);
   }
}
