GOF创建型模式：抽象工厂模式

package AbstractFactory;

public interface seat {
    void massage();
}

class luxurySeat implements seat{
    public void massage() {
        System.out.println("能***");
    }

    }

package AbstractFactory;

void run();
void start();
}

    public void run() {
        System.out.println("转的快");
    }

    public void start() {
        System.out.println("启动快");
    }

    public void run() {
        System.out.println("转的慢");
    }

    public void start() {
        System.out.println("启动慢");
    }
}

package AbstractFactory;

    }
}

package AbstractFactory;
