Question

Please do in a basic Java program and comment so that I understand what is going on.

Write a program that gives the statistics of a die being rolled 1000 times! Use a random number generator that picks only the number 1 through 6 and keep tally on each of each time the number is rolled. Store the number of times each number is rolled in the corresponding array index 1-6. For example, you will count the number of times the number 1 is rolled and store that value in index 1.

Note 1: You will not store anything in index 0.
Note 2:
import java.util.Random; //import Random class
Random rand = new Random(); //create instance of Random class
1 + rand.nextInt(10); //generates a random number between 1 and 10

Print the statistics at the end of the program.

Example output
1-563
2-105
3-52
4-201
5-70
6-9

Answer 1

import java.util.Random;

public class DiceStatistics {

    public static void main(String[] args) {
        Random rand = new Random(); //create instance of Random class
        int[] counts = {0, 0, 0, 0, 0, 0, 0};
        int num;
        for (int i = 0; i < 1000; i++) {
            num = 1 + rand.nextInt(6);  // rolls a number from 1 to 6
            counts[num]++;  // increase the count for num
        }
        for (int i = 1; i <= 6; i++) {
            System.out.println(i + "-" + counts[i]);    // display count for i
        }
    }
}
