我为2d游戏创建了一个抽象的形状类,但我在两个形状类中都出错.该错误与super()有关.可能还有其他错误.我还显示了我在代码中得到错误的位置.IS super()适合使用.

形状类

public abstract class Shape {

    int Y;
    int WIDTH;
    int HEIGHT;
    int DIAMETER;

    public Shape(int Y, int WIDTH, int HEIGHT, int DIAMETER) {
        this.Y = Y;
        this.WIDTH = WIDTH;
        this.HEIGHT = HEIGHT;
        this.DIAMETER = DIAMETER;
    }

    public abstract void paint(Graphics g);

}

球拍类

public class Racquet extends Shape {

    int x = 0;
    int xa = 0;
    private Game game;

    public Racquet(int Y, int WIDTH, int HEIGHT) {
        super(Y, WIDTH, HEIGHT); // <- **Error Here**

    }

    public …
