Write a program that Roll Dice 6000000 times

Input:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53

import java.util.Random; public class RollDie { /** * @param args the command line arguments */ public static void main(String[] args) { Random rnd = new Random(); // random number generator int frequency1 = 0; // maintains count of 1s rolled int frequency2 = 0; // count of 2s rolled int frequency3 = 0; // count of 3s rolled int frequency4 = 0; // count of 4s rolled int frequency5 = 0; // count of 5s rolled int frequency6 = 0; // count of 6s rolled int face; // most recently rolled value // tally counts for 6,000,000 rolls of a die for (int roll = 1; roll <= 6000000; roll++) { face = 1 + rnd.nextInt(6); // determine roll value 1-6 and increment appropriate counter switch (face) { case 1: ++frequency1; // increment the 1s counter break; case 2: ++frequency2; // increment the 2s counter break; case 3: ++frequency3; // increment the 3s counter break; case 4: ++frequency4; // increment the 4s counter break; case 5: ++frequency5; // increment the 5s counter break; case 6: ++frequency6; // increment the 6s counter break; // optional at end of switch } // end switch } // end for System.out.println("Face\tFrequency"); // output headers System.out.printf("1\t%d\n2\t%d\n3\t%d\n4\t%d\n5\t%d\n6\t%d\n", frequency1, frequency2, frequency3, frequency4, frequency5, frequency6); } }

Output / Run:

Face Frequency
1 999981
2 1000458
3 1000487
4 999078
5 999474
6 1000522
