How to Make a Dice Simulator Using Java

Step-by-Step Guide

1. 1

   Step 1: Open your IDE application on your computer.

   Name it DiceSimulator.
   
   If it makes a main class automatically, call that class DiceTester. , In this Dice file, import the random package: import java.util.Random
2. 2

   Step 2: Create a new project.

   ,,,, If DiceTester is your main class, go straight to DiceTester instead. ,,,,,,, Within this loop, you construct each Dice object by using the for loop variable x and passing the variable howManySides. ,,, In many IDE its by pressing the green play button on the top left corner of your IDE application.
3. 3

   Step 3: Create a new class and name it Dice.

4. 4

   Step 4: Within the Dice class

5. 5

   Step 5: initiate a random variable: Random randomGenerator = new Random();

6. 6

   Step 6: Initiate an integer variable to indicate the number of sides: int sides = 0;

7. 7

   Step 7: Create the constructor for Dice to define the number of sides the dice class would have: public Dice (int numberOfSides) { sides = numberOfSides;}

8. 8

   Step 8: Create a method to return a random number between 1 and the number of sides: public int roll() {int result = randomGenerator.nextInt(sides) + 1; return result; }

9. 9

   Step 9: Create the main class and name it DiceTester.

10. 10

    Step 10: At the top of the DiceTester class

11. 11

    Step 11: import the scanner package: import java.util.Scanner;

12. 12

    Step 12: Create a Scanner object in the main method and name it in.

13. 13

    Step 13: Print out the question: “How many dice do you need?” If you're new to programming

14. 14

    Step 14: use System.out.println(" "); to print statements.

15. 15

    Step 15: Initiate an integer variable called howManyDice and assign it to the integer the user inputs: int howManyDice = in.nextInt();

16. 16

    Step 16: Print out the question: “How many sides do each dice have?”

17. 17

    Step 17: Initiate an integer variable called howManySides and assign it to the integer the user inputs: int howManySides = in.nextInt();

18. 18

    Step 18: Create a for loop that iterates once for every dice the user wishes to create.

19. 19

    Step 19: Call the roll method from Dice and display it in the loop to get all the results.

20. 20

    Step 20: Check that the loop looks similar to the following code: for (int x = 0; x < howManyDice; x++) {theDice= new Dice(howManySides); int result = theDice.roll(); System.out.println("Roll of dice #" + (1 + x) + ": " + result); }

21. 21

    Step 21: Run the program!
