Question

Using the Die class defined in this chapter, design and implement 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.

I need the main method or test class

public class Die
{
private final int MAX = 6; // maximum face value

private int faceValue; // current value showing on the die

//-----------------------------------------------------------------
// Constructor: Sets the initial face value.
//-----------------------------------------------------------------
public Die()
{
faceValue = 1;
}

//-----------------------------------------------------------------
// Rolls the die and returns the result.
//-----------------------------------------------------------------
public int roll()
{
faceValue = (int)(Math.random() * MAX) + 1;

return faceValue;
}

//-----------------------------------------------------------------
// Face value mutator.
//-----------------------------------------------------------------
public void setFaceValue (int value)
{
faceValue = value;
}

//-----------------------------------------------------------------
// Face value accessor.
//-----------------------------------------------------------------
public int getFaceValue()
{
return faceValue;
}

//-----------------------------------------------------------------
// Returns a string representation of this die.
//-----------------------------------------------------------------
public String toString()
{
String result = Integer.toString(faceValue);

return result;
}
}

Code: public class PairOfDice //creating the objects private Die d1 new Die (); private Die d2 new Die () //gettina first die value public void initial value (int value) d1.setFaceValue (value); //getting second die value public void nextl value (int value) d2.setFaceValue (value) //returns first die value public int Get First Value () return d1.getFaceValue ) //returns second die value public int Get Second Value () return az-getracevalue (); //sum up the vlue of first die and second die public int getValue () return Get First Value+ Get Second Value //method to roll public int RollTheDie () return d1.RollTheDie) + d2.RollTheDie ();

public String toStrina) String result = Integer. t String getValue()); return result; public class RollingDice2 //main method public static void main (String l args) //to create an object PairOfDice myDice - new PairOfDice ); System.out.println ("Rolling the dice. . ."); myDice.RollTheDie ) System.out.print ("gettina first die value" + System.out.println(" qgetting second die value"+ System.out.println ("sum of value "+ myDice.toString () myDice.Get First Value ( myDice.Get Second Value) +" ."); +I System.out.println ("setting values to maximum number of die."); myDice.initial value (6); myDice.nextl value (6); System.out.println ("value is"+ myDice.toStrina )+
code:

public class PairOfDice

{

     //creating the objects

     private Die d1 = new Die();

     private Die d2 = new Die();

     //getting first die value

     public void initial_value(int value)

     {

          d1.setFaceValue(value);

     }

    

     //getting second die value

     public void nextl_value(int value)

     {

          d2.setFaceValue(value);

     }

    

     //returns first die value

     public int Get_First_Value()

     {

          return d1.getFaceValue();

     }

    

     //returns second die value

     public int Get_Second_Value()

     {

          return d2.getFaceValue();

     }

    

     //sum up the vlue of first die and second die

     public int getValue()

     {

          return Get_First_Value() + Get_Second_Value();

     }

    

     //method to roll

     public int RollTheDie()

     {

          return d1.RollTheDie() + d2.RollTheDie();

     }

    

    

public String toString()

     {

          String result = Integer.toString(getValue());

         

          return result;

     }

}

public class RollingDice2

{

     //main method

     public static void main(String[] args)

     {

          //to create an object

         PairOfDice myDice = new PairOfDice();

         System.out.println("Rolling the dice...");

         myDice.RollTheDie();

        

         System.out.print("getting first die value " + myDice.Get_First_Value());

         System.out.println(" getting second die value " + myDice.Get_Second_Value() + ".");

         System.out.println("sum of value " + myDice.toString() + ".");

        

         System.out.println("setting values to maximum number of die.");

         myDice.initial_value(6);

         myDice.nextl_value(6);

         System.out.println("value is " + myDice.toString() + "!");

        

     }
