Random dice role program in Java

Welcome, in this tutorial we create a dice program in java that generates a random number between 1 to 6. we use a java.util.Random class to generate the numbers between the specific range.

Code with explanation: Random dice role

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

public class DiceExample {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the dice roll count: ");
        int numberOfDice = input.nextInt();
        if (numberOfDice == 0) {
            System.out.println("Input rollcount is 0" + "\n" + "Number of dice incremented to 1.");
            numberOfDice++;
        }
        diceRolled(numberOfDice);
        input.close();
    }

    public static void diceRolled(int a) {
        int dice;
        int result = 0;
        int total = 0;
        Random randomObj = new Random();
        System.out.print("Dice rolled : ");
        for (dice = 1; dice <= a; dice++) {
            result = randomObj.nextInt(6) + 1;
            total += result;
            System.out.print(result + " ");

        }

        System.out.println("\n" + "Total  = " + total);

    }

}

When the user enters 0, the output is.

Output
Enter the dice roll count: 0
Input rollcount is 0
Number of dice incremented to 1.
Dice rolled : 6 
Total = 6

When the user enters a value greater than 0, the output is.

Output
Enter the dice roll count: 2
Dice rolled : 2 3 
Total = 5

Explanation

  • In the main body, The code starts by creating a Scanner object called input.
  • The code prints “Enter the dice roll count: “ and asks for an integer value from the user.
  • If the number of dice is 0, then it increments to 1 and executes the following line of code.
  • Line 14, code calls a function named diceRolled() that takes in an integer value as its argument.
  • Line 18, The function calculates how many times each dice has been thrown and displays the result on the screen with the total value of the result.

That’s enough for a quick overview of the Random dice role program in Java.
