Thread: Dice Program Help

I have to roll a pair of dice and count the number of box cars (two sixes) that occur, here is what I have:

 import java.util.*;
 
 public class BoxCar{
 
     public static void main (String [] args){
 
         //Declare two dice, and a counter
         PoD die1, die2;
         int counter; // To tell how many times to roll the dice
         int setNumDie1; //Set number to be used in die1.setFaceValue
         int setNumDie2; //Set number to be used in die2.setFaceValue
         int sum;
         int totalBox;
 
         Scanner scan = new Scanner (System.in);
 
         //Declares di1 and die2 as dice
         die1 = new PoD();
         die2 = new PoD();
 
         //Set the counter to 10, able to count down to 0
         counter = 1000;
 
 
         //This section of code demonstrates the setFaceValue mothod 
         //by asking the user to input of the each die they would 
         //like to start at.
         System.out.println ("Please enter a number between 1 and 6:");
         System.out.print ("Die 1: ");
         setNumDie1 = scan.nextInt();
         System.out.print ("Die 2: ");
         setNumDie2 = scan.nextInt();
         die1.setFaceValue(setNumDie1);
         die2.setFaceValue(setNumDie2);
 
         //This shows the dice are set at the user inputed number,
         //and show the sum just becuase
         System.out.println ("You set the value of Die #1 at: " +
            die1.getFaceValue() + " and Die #2 at: " + die2.getFaceValue());
         sum = die1.getFaceValue() + die2.getFaceValue();
         System.out.println ("The sum of the two dice are: " + sum);
 
         //The reason counter is there and not the number ten,
         //is that a simple change in code by allowing the user to 
         //enter counter, it will count that many times.
         System.out.println ("Now we will roll the dice " + 
            counter + " times.");
 
         //This statement means that as long as counter is less than ten
         //it will keep rolling, Once it reaches ten it will stop.
         while (counter > 0){
             die1.roll(); //Rolls die1
             die2.roll(); //Rolls die2
              if ((die1 == 6) && (die2 == 6)){
                totalBox ++;
            }
             System.out.println ("Die one: " + die1 + ", Die two: " + die2); 
             counter-- ; //Adds 1 to the value to counter
        }
 
 
    }    
}

Where i have the code line " if ((die1 == 6) && (die2 == 6)){
totalBox ++;"

all i get is that PoD and int are incomparable types. What am i doing wrong. I cant get the program to count the number of times the dice roll two sixes

PoD and int are incomparable types

The die variables are NOT int. You need to add a method to the PoD class that takes an int and tests the die's face value against it.
