我正在尝试装饰器.我创建了一个Tank类和两个装饰器:DoubleGunTank(射击更强大)和FasterTank(驱动更快).他们来了:

public class Tank {
    public int shoot() {
        return 100;
    }

    public int drive() {
        return 10;
    }
}
public class FasterTank extends Tank {

    protected Tank fTank;

    public FasterTank(Tank tank) {
        fTank = tank;
    }

    public int drive() {
        return fTank.drive() * 2;
    }
}

public class DoubleGunTank extends Tank {

    protected Tank fTank;

    public DoubleGunTank(Tank tank) {
        fTank = tank;
    }
    public int shoot() {
        return fTank.shoot() * 2;
    }   
}
