Question

Please Help! I need to update the code below to meet these criteria!

1. The constructor of die class initializes face of Die to 3

2. roll method updates face of die to value from 1-6

3. getFace() method provides current face to the main program

4. main create a Die object

5. main create a Die object

6. main rolls die 5 times

7. main computes sum of rolls

8. main computes actual average of the rolls

<--------- Code Listed Bellow -------->

import java.util.Random;

public class Die {
  
private final int MAX = 6;
  
private int face; //value showing on the face of the die

private Random rand = new Random(); //random object to use for rolling

//constructor whcih initializes the die to show a 3
public Die() {
faceValue = 3;
}

//rolls the die and updates it's face
public void roll() {
faceValue = (int)(Math.random() * MAX) + 1;
return faceValue;
}

  
//returns the value of the die face
public int getFace() {
return faceValue;
}

//tests the Die class
public static void main (String [] args) {
  
String result = Integer.toString(faceValue);

return result;

}

}

JAVA CODE:

import java.util.Scanner;
import java.util.Random;

public class Die
{
   private final int MAX = 6;
  
private int faceValue; //value showing on the face of the die

private Random rand = new Random(); //random object to use for rolling

//constructor whcih initializes the die to show a 3
public Die() {
faceValue = 3;
}

//rolls the die and updates it's face
public int roll() {
faceValue = (int)(Math.random() * MAX) + 1;
return faceValue;
}

//returns the value of the die face
public int getFace() {
return faceValue;
}
   public String toString()
{
String result = Integer.toString(faceValue);
return result;
}

//tests the Die class
public static void main (String [] args) {

   Die die1, die2;
int sum=0;
   float avg;

   // create a Die object
   die1 = new Die();
   // create a Die object
die2 = new Die();
   // rolls die 5 times
   int rollCount =5;
   // rolls die 5 times
   while(rollCount>0){
       // rolls dies
       die1.roll();
       die2.roll();
       // display the dies
System.out.println ("Die One: " + die1.getFace() + ", Die Two: " + die2.getFace());
       // computes sum of rolls
   sum+=die1.getFace();
       sum+=die2.getFace();
         
       rollCount--;// rollCount decrement by 1
   }
   // computes actual average of the rolls
   avg = (float)sum / 5;
   // display the sum
   System.out.println("Sum: "+sum);
// display the average
   System.out.println("Average: "+avg);

   }
}
