Week 6: Methods of OO Programming/15. The Last Piece, Part 2: The GamePiece Class

Next, let's write the 'GamePiece' class.

Define the class so that it cannot be inherited.

The class should have the following features:

Constructor, which takes the color (an integer) as a parameter
Get method getColor, which returns the color





import java.util.Random;

public class Test{
    public static void main(String[] args){
        final Random r = new Random();
        
        System.out.println("Testing the GamePiece class...");

        GamePiece p1 = new GamePiece(Color.BLACK);
        System.out.println("GamePiece created");
        System.out.println("GamePiece is final: "  + (p1.getClass().getModifiers() > 15));

        System.out.println("Calling observation method...");
        System.out.println("getColor() returns " + p1.getColor());




        p1 = new GamePiece(Color.WHITE);
        System.out.println("GamePiece created");

        System.out.println("Calling observation method...");
        System.out.println("getColor() returns " + p1.getColor());

    }
}


//ADD
final class GamePiece {
    private int color;

    // constructor
    public GamePiece(int color) {
      this.color = color;
    }

    public int getColor() {
        return this.color;
    }
}




Testing the GamePiece class...
GamePiece created
GamePiece is final: true

Calling observation method...
getColor() returns 2


GamePiece created
Calling observation method...
getColor() returns 1
