Question

Write an application that: 1. Prompts the user for a number of trials to perform (I will call this "N"). This operation should be type-safe for integers. 2. Simulates N trials of rolling two dice and finding the sum. 3. Uses an array to keep track of how many times each outcome has been rolled (you do not need to keep track of the actual rolls themselves). 4. Computes the percentage of the total number of rolls for each outcome it may be useful to store this as a separate array of doubles). 5. Outputs the results in a table similar to the one below (note that your results will be different since a random number generator is being used) 300 Enter the number of trials: Outcome Number Percent 2.0% 7.7% 6.3% 13.7% 12.78 16.7% 12.7% 11.3% 9.0% 5.3% 2.7%

Thanks for the question.

Below is the code you will be needing  Let me know if you have any doubts or if you need anything to change.

Thank You !!

import java.util.Random;
import java.util.Scanner;

public class Trials {

    public static void main(String[] args) {

        int[] sumCount = new int[11];
        int trials = 0;
        Scanner scanner = new Scanner(System.in);
        // using try catch to make it type safe

        System.out.print("Enter the number of trials: ");
        trials = (int) scanner.nextDouble();
        Random random = new Random();
        int diceOne = 0, diceTwo = 0;
        for (int trial = 1; trial <= trials; trial++) {
            diceOne = random.nextInt(6) + 1;
            diceTwo = random.nextInt(6) + 1;
            int sum = diceOne + diceTwo;
            sumCount[sum - 2] += 1;
        }

        System.out.printf("\n%10s%10s%10s\n", "Outcome", "Number", "Percent");
        for (int i = 0; i < sumCount.length; i++) {
            System.out.printf("%10d%10d%9.1f%1s\n", i + 2, sumCount[i],
                    sumCount[i] * 100.0 / trials, "%");
        }

    }
}
