OOP-继承 [英] OOP - Inheritance

问题描述

如果我有一堂课，请上动物课.

If I have a class, class Animal.

我有一个Dog和Cat都继承了Animal.

And I have a class Dog and a class Cat both inheriting Animal.

Cat可以在Animal内部调用方法.但是Cat可以调用Dog的方法吗?

Cat can call methods inside Animal. But can Cat call methods of Dog?

推荐答案

在超类中定义的方法可用于任何子类.但是姐妹"类无法访问彼此的(私有)方法.

The methods defined in a superclass are accesible to any subclass. But "sister" classes cannot access the (private) methods of one another.

因此，如果您的类Cat和Dog继承自Animal，则Cat和Dog对象都可以从Animal调用方法，但是它们不能(必须 )互相访问方法.

So if your classes Cat and Dog inherit from Animal, then both Cat and Dog objects can call methods from Animal, but they cannot (must not) access the methods of each other.
