Write A Complete Java Program That Simulates The Rolling Of A Pair Of

Write a complete Java program that simulates the rolling of a pair of dice. For each die in the pair, the program should generate a random number between 1 and 6 (inclusive). It should print out the result of the roll for each die and the total roll (the sum of the two dice), all appropriately labeled. You must use the Random class. The RandomNumbers program in listing 3.2 of the text may be helpful. Your program will perform rolling of Dice pair three rounds. Sample test run results (Note your results will be different from these outputs) First round You rolled 1 and 1 for a total of 2. Second round You rolled 4 and 2 for a total of 6. Third round You rolled 6 and 4 for a total of 10.

Java Program to Simulate Rolling of a Pair of Dice

This paper presents a comprehensive Java program designed to simulate the rolling of a pair of dice over three rounds. The program utilizes the Random class from Java's standard library to generate pseudo-random numbers between 1 and 6, effectively mimicking the behavior of actual dice rolls. For each round, the program outputs the outcome of each die, along with their sum, providing a clear and labeled result. The implementation emphasizes clarity, correctness, and adherence to the specified requirements.

Introduction

Rolling dice is a common activity in many board games and probability exercises. Simulating dice rolls through programming enables automation of numerous game scenarios, statistical analysis, and educational demonstrations. Java's Random class provides a convenient way to generate random numbers, ensuring reproducibility and ease of implementation. The following program encapsulates these ideas by performing three rounds of rolling two dice, displaying each die's value, and computing their total.

Program Design

The program is structured around the following elements:

  • Importing the java.util.Random class.
  • Creating an instance of Random.
  • Implementing a loop that runs exactly three times, representing three rounds of dice rolls.
  • Within each iteration:
    • Generating two random integers between 1 and 6 for the dice.
    • Printing the results in a clear, labeled format.
    • Calculating and displaying the total of the two dice.

Implementation

The Java code begins by importing the java.util.Random class. It then instantiates an object of this class to generate random numbers. A for loop iterates three times, representing each round of rolling. During each iteration:



import java.util.Random;


public class DiceRollingSimulation {


public static void main(String[] args) {


Random rand = new Random();


for (int round = 1; round 

int die1 = rand.nextInt(6) + 1; // Generates number 1-6


int die2 = rand.nextInt(6) + 1; // Generates number 1-6


int total = die1 + die2;


System.out.println("Round " + round + ":");


System.out.println("You rolled " + die1 + " and " + die2 + " for a total of " + total + ".");


}


}


}

This code ensures randomness by using rand.nextInt(6) + 1, which produces values from 1 to 6 inclusive. Each iteration outputs a statement indicating the round number, the individual dice results, and their sum, hence fulfilling the specified requirements.

Sample Output

Note: Actual results vary with each execution due to randomness, but an example run may look like:

Round 1:


You rolled 3 and 5 for a total of 8.


Round 2:


You rolled 2 and 2 for a total of 4.


Round 3:


You rolled 6 and 1 for a total of 7.

Conclusion

This Java program effectively simulates the rolling of a pair of dice over three rounds using the Random class. It demonstrates fundamental programming concepts such as loops, random number generation, and formatted output. Such simulations are useful in developing understanding of randomness, probability, and game-related programming tasks.
