Task #1 While loop
1. DiceSimulation.java
is incomplete. Since there is a large part of the program missing, the output will
be incorrect if you run DiceSimulation.java.
2. I have declared all the variables. You need to add code to simulate rolling the
dice and keeping track of the doubles. Convert the algorithm below to Java and
place it in the main method after the variable declarations, but before the output
statements. You will be using several control structures: a while loop and an ifelse-
if statement nested inside another if statement. Use the indenting of the
algorithm to help you decide what is included in the loop, what is included in
the if statement, and what is included in the nested if-else-if statement.

Program Dice.java

=================================================

import java.util.Random;

public class Dice
{
    private int spots; //the number of spots up on the die
    private static Random generator;
    //a random number generator use simulating rolling dice,
    //shared by all dice, so that it will be as random as possible

    //constructor creates a single die, inititally with no spots
    public Dice()
    {
//create an instance of the random
        generator = new Random();
        spots = 0;
    }

    //simulates rolling the die and stores the numbers rolled
    public void roll()
    {
//return 1,2,3,4,5, or 6
        spots = generator.nextInt(6) + 1;
    }

    //return the value of the die
    public int getSpots()
    {
        return spots;
    }
}

Program DiceSimulation.java

=========================================================

public class DiceSimulation
{
    public static void main(String [] args)
    {

        final int NUMBER = 10000; //the number of times the roll the dice

        Dice die1 = new Dice(); //first die
        Dice die2 = new Dice(); //second die

        int die1Value; //the number of spots on the second die
        int die2Value; //the number of spots on the first die
        int count = 0; //number of times the dice were rolled
        int snakeEye = 0; //number of times of snakes eyes is rolled

//number of times double two's, three's, four's, five's, six's
        int twos = 0;
        int threes = 0;
        int fours = 0;
        int fives = 0;
        int sixes = 0;

//ENTER YOUR CODE FOR THE ALGORITHM HERE
        for(count=0;count<=NUMBER;count++)
        {
            die1.roll();
            int t1=die1.getSpots();
            die2.roll();
            int t2=die2.getSpots();

            if(t1==t2)
            {
                if(t1==1)snakeEye++;
                else if(t1==2)twos++;
                else if(t1==3)threes++;
                else if(t1==4)fours++;
                else if(t1==5)fives++;
                else if(t1==6)sixes++;
            }
        }
        count--;


//output to console

        System.out.println("You rolled snake eyes " + snakeEye
                + " out of " + count + " rolls.");
        System.out.println("You rolled double two " + twos
                + " out of " + count + " rolls.");
        System.out.println("You rolled double threes " + threes
                + " out of " + count + " rolls.");
        System.out.println("You rolled double fours " + fours
                + " out of " + count + " rolls.");
        System.out.println("You rolled double fives " + fives
                + " out of " + count + " rolls.");
        System.out.println("You rolled double sixes " + sixes
                + " out of " + count + " rolls.");
    }
}
