        Animal a1 = new Animal();
        Debug.Log(a1.Info());
        Animal a2 = new Animal("a2", 3);
        Debug.Log(a2.Info());

        Dog d1 = new Dog();
        Debug.Log(d1.Info());
        Dog d2 = new Dog("d2", 2, 1);
        Debug.Log(d2.Info());
    }
}

如示例，既可以继承自己的构造方法，也可以继承父类的构造方法。
