Answer to Question #17752 in Java | JSP | JSF for Sayed Abdullah Almousawi

Question

Probability: Rolling 6 sided dice can teach us about probability.
Allow the user to choose a number of rolls for 2 six sided dice. Use random number generator to produce the resulting rolls.

Add the dice together and keep track of how many of each of the sums are rolled. Print out a frequency distribution table and then a frequency histogram

Answer 1

import java.util.Arrays;
import java.util.Scanner;

public class Dice {

public static void main(String[] args) {
& @SuppressWarnings("resource")
& Scanner input= new Scanner(System.in);
& System.out.print("Choose a number of rolls for 2 six sided dice: ");
& int in=input.nextInt();
& int[] summarr = new int [12];
& Arrays.fill(summarr,0);
& for (int i = 0; i<in; i++) {
& summarr[throwDice() + throwDice() - 1]++;
& }
& for (int i = 2; i<13; i++) {
& System.out.printf("%2d& %d",i,summarr[i-1]);
& System.out.println();
&
& }
}
public static int throwDice () {
& return ((int) (Math.random() *6) + 1) ;
}

}
