Answer to Question #278692 in Java | JSP | JSF for Hab1bti

Question

1.

Create a file called

Die.java

, with an empty class in it.

2.

Add a new (private) field to the class to store the number of sides. You probably want this to

be an

int

.

3.

Create

a

constructor

for

Die

that

takes

one

argument,

an

int

representing

the

number

of

sides.

If the number is less than 2, store 6 as the number of sides in the class field.

Other-

wise, store the number given.

4.

Create a no-argument constructor.

It should assume the number of sides is six.

You can do

this in one line with the

this()

constructor, but that isn’t required to get full credit.

5.

Add a

roll()

method to your

Die

, which takes no arguments and returns an

int

between 1

and the number of sides (inclusive).

Answer 1

import java.util.Scanner;


class Die {
	private int numberSides;


	public Die() {
		this.numberSides = 6;
	}


	public Die(int numberSides) {
		if (numberSides < 2) {
			this.numberSides = 6;
		} else {
			this.numberSides = numberSides;
		}
	}


	public int roll() {
		return (int) (Math.random() * numberSides) + 1;
	}
}


public class App {


	/**
	 * The start point of the program
	 * 
	 * @param args
	 * 
	 */
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter the number of sides: ");
		int numberSides = keyBoard.nextInt();
		Die die = new Die(numberSides);


		System.out.println(die.roll());
		keyBoard.close();
	}
}
