Question

Write an application to simulate the rolling of two dice the application should use an object of class Random once to roll the Fust die and again to roll the second die, the sum of the two values should then be calculated Each die can show an integer value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent. Figure 6.36 m your textbook shows the 36 possible combinations of the two dice. Your application should roll the dice 36,000 times. Use a one-dimensional array to tally the number of times each possible sum appears Display the results in tabular format Determine whether the totals are reasonable. Your output from your program should resemble the following:

Explanation / Answer

TwoDice36000.java

import java.text.DecimalFormat;
import java.util.Random;

public class TwoDice36000 {

   public static void main(String[] args) {
      
       final int ROLLS = 36000;
       final int SIZE = 13;
         
       //Declaring variables
       int x; // first die
       int y; // second die
       double percentage;
         
       //Creating an array
       int freq[]=new int[SIZE];
         
       //Creating an random class object
       Random r = new Random();
         
       //DecimalFormat class is used to format the output
               DecimalFormat df=new DecimalFormat("##");
                 
       // roll dice 36,000 times
       /* Write a for loop that iterates ROLLS times. Randomly
       generate values for x (i.e., die1) and y (i,e, die2)
       and increment the appropriate counter in array sum that
       corresponds to the sum of x and y */
       for(int i=0;i<ROLLS;i++)
       {
       x=r.nextInt(6) +1;
       y=r.nextInt(6) +1;
       freq[x+y]++;
       }
         
       //Displaying the table
       System.out.println("Sum Frequency Percentage");
       for(int i=2;i<13;i++)
       {
           percentage=((double)freq[i]/ROLLS)*100;
           System.out.println(i+" "+freq[i]+" "+df.format(percentage));
       }

   }

}
