Question

PLEASE HELP WITH JAVA!
You've been hired by Cube Counters to write a Java console application that repeatedly rolls two ten-sided dice and tabulates the results. To roll the dice, randomly generate two numbers between 1 and 10. Add the two numbers together and increment the counter for that sum. Possible sums range from 2 to 20 so store the counters in an integer array of 19 elements. Roll the dice 100,000 times. Format the output in three columns with the first column containing a sum, the second column containing the count, and the third column containing the percentage of that count over 100,00. Print the total rolls and percentage. These should be 100,000 and 100%, respectively. Format the counts with commas. Format the percentages with two decimal places. PLEASE HELP WITH JAVA!

Explanation / Answer

import java.util.Random;
public class Cubes{
   public static void main(String args[]){
       Random rand = new Random();
       int m,n,sum;
       int tr = 100000;
       int[] counter = new int[19];
       for(int i=0;i<tr;i++){
           // get two random number between 1 and 10.
           m = rand.nextInt(10)+1;
           n = rand.nextInt(10)+1;
           sum = m+n;
           // increment counter of sum-2 index.
           counter[sum-2] = counter[sum-2]+1;
       }
       System.out.println("SUM,Count,Percentage");
       for(int i=0;i<19;i++){
           System.out.println((i+2)+","+counter[i]+","+((counter[i]*100.0)/tr));
       }
       System.out.println("Total rolls:"+tr+" Total Percentage:"+100);

   }
}
