Question

Can anyone help me with this java program? We are still very early with lessons so no advanced code please. And if you comment throughout the code that would be incredibly helpful. Thank you

Create 2 Java files for this assignment: Die.java and TestDie.java

Part 1 - The Die Class

            The program

Design a Die class that contains the following attributes:

• sides: represents how many sides a dice has. A dice usually has 6 sides but sometimes could have more. This will be provided by the user
• value: represents the current value that was rolled in the dice.

The die Class should have the following methods:

• Constructor: takes one parameter that represents the number of sides in the dice. It then rolls the dice to give it an initial value
• Accessor methods: Should return the fields of the Die class.
• roll: Randomly generates a value within the number of sides of the dice. For example, if the dice has 6 sides you need to set value to be a random number between 1 and 6. If the dice has 12 sides, you need to set the value to a random number between 1 and 12 and so on… (Hint, this function is of type VOID)

Part 2 – The TestDie Class

            The Program

The program should create two instances of the Die class (each a six-sided die). One Die object is the computer’s die, the other Die object is the user’s die.

The program should have a loop that iterates 20 times. Each time the loop iterates, it should roll both dice. The die with the highest value wins. (In case of a tie, there is no winner for that particular roll of the dice).

As the loop iterates, the program should keep count of the number of times the computer wins, and the number of times that the user wins. After the loop performs all of its iterations, the program should display who was the grand winner, the computer or the user.

Finally, if the user wins, the program must ask the user to enter a nickname (The nickname must be at least 1 character and at most 5 characters), keep asking to user to enter a name while it is not valid. Once the user enters their nickname, append their nickname and number of wins to a file called “scores.txt”. Opening this file will contain the score of every player that has won the game.

Answer 1

thanks for the question, here are the two classes, i have commented the code as much as possible. Hope it helps you

let me know for any quesitons

import java.util.Random;

public class Die {

    //sides: represents how many sides a dice has.
    private int sides;
    //value: represents the current value that was rolled in the dice.
    private int value;

    //Constructor: takes one parameter that represents the number of sides in the dice.
    public Die(int sides) {
        this.sides = sides;
        //It then rolls the dice to give it an initial value
        roll();

    }

    //roll: Randomly generates a value within the number of sides of the dice.
    public void roll() {
        value = new Random().nextInt(sides) + 1;
    }

    //getter method to get the value
    public int getValue() {
        return value;
    }

    // getter method to get the number of sides
    public int getSides() {
        return sides;
