# Dice Roll Program Java

Dice Roll Program Java | In this post, we will write a Java program to roll a dice or multiple dice at a time. Dice is a cube having 6 faces each faces is denoted by numbers from 1 to 6, when you roll a dice you get any of these numbers.

We are about to write the program for it in Java programming language. To know more observe the below examples:-

1) Roll a dice:
Outcome: 4

2) Roll a dice:
Outcome: 6

We can also roll multiple dice at a time. Example for rolling two dice at a time.

1) Number of dice: 2
Roll the dice.
Outcome: 2, 6

2) Number of dice: 2
Roll the dice.
Outcome: 1, 6

As there are only 6 numbers in the dice there is no possibility of getting any numbers more than 6.

## Dice Roll Program Java Code

Now let us see the Java dice roll program. It is a very simple Java program using the Random class to generate an integer number between 0 to 5. In the generated value 1 is added.

``````import java.util.Random;

public class Main {
public static void main(String args[]) {
Random random = new Random();
System.out.print("The value on dice is: "
+ (random.nextInt(6) + 1));
}
}``````

Output:-

The value on dice is: 5

The value on dice is: 3

The value on dice is: 6

## Roll Two Dice Java Program

The below dice roll program Java not only can roll a single dice, but it can also roll multiple dice at a time. For rolling, we are taking the help of the Random class defined in java.util package. The nextInt() method of the Random class will generate a new digit between 1 and 6.

Java Program for Rolling Two Dice

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

public class Main {
public static void main(String args[]) {

System.out.print("Enter the number of dice (>0): ");
Scanner scan = new Scanner(System.in);
int num = scan.nextInt();

while (num <= 0) {
System.out.println("The number of dice can't"+
" be 0 or -ve.");
System.out.print("Enter number of dice: ");
num = scan.nextInt();
}

Random rand = new Random();
do {
System.out.println("The values on dice are: ");
for (int i = 0; i < num; i++) {
System.out.println(rand.nextInt(6) + 1);
}
System.out.print("Do you want to roll the" +
" dice again? true/false: ");
} while (scan.nextBoolean() == true);
scan.close();
}
}``````

Output:-

Enter the number of dice (>0): 1
The values on dice are:
5
Do you want to roll the dice again? true/false: true
The values on dice are:
5
Do you want to roll the dice again? true/false: true
The values on dice are:
6
Do you want to roll the dice again? true/false: false

Enter the number of dice (>0): 0
The number of dice can’t be 0 or -ve.
Enter number of dice: -5
The number of dice can’t be 0 or -ve.
Enter number of dice: 1
The values on dice are:
1
Do you want to roll the dice again? true/false: false

Enter the number of dice (>0): 2
The values on dice are:
1
1
Do you want to roll the dice again? true/false: true
The values on dice are:
1
6
Do you want to roll the dice again? true/false: true
The values on dice are:
3
5
Do you want to roll the dice again? true/false: false

The above roll two dice java program is able to roll multiple dice simultaneously. Also see:- Hidden Word Java Program
