Question

Write a program to simulate rolling three dices simultaneously. Keep rolling these
three dices until the three dices show the values of “1”, “2”, and “3” (we call this
condition 1. The dices are in no particular orders to show these values in this case).
Then the program shows the values of the three dices and the number of rolling so
far. After that the rolling continues (and counting of the number of rolling
continues too) until the first dice shows the value of “1” while condition 1 is also
satisfied. Your program then shows the total number of rolling and stops. You are
encouraged to simplify the logical expressions, with less operands and operators,
used in your program.
The output of your program is similar to:
Number of rolling Value1 Value2 Value3
38 3 1 2
83 2 1 3
157 3 1 2
177 1 2 3
Total number of rolling: 177
This should be for a java program.

Answer 1

import java.util.Random;

public class Roll123 {

    public static void main(String[] args) {
        int count = 0, n1, n2, n3;
        Random random = new Random();
        System.out.println("Number of rolling Value1 Value2 Value3");
        while (true) {
            count++;
            n1 = random.nextInt(6) + 1;
            n2 = random.nextInt(6) + 1;
            n3 = random.nextInt(6) + 1;
            if (n1 == 1 && n2 == 2 && n3 == 3) {
                System.out.println(count + " 1 2 3");
                break;
            }
            if ((n1 == 1 || n2 == 1 || n3 == 1) && (n1 == 2 || n2 == 2 || n3 == 2) && (n1 == 3 || n2 == 3 || n3 == 3)) {
                System.out.println(count + " " + n1 + " " + n2 + " " + n3);
            }
        }
        System.out.println("Total number of rolling: " + count);
    }
}
