后期绑定与多态性-有什么区别? [英] Late Binding vs. Polymorphism - what is the difference?

问题描述

我已经看到两者互换使用了，但是它们的意思真的一样吗?根据我的理解，多态性扩展了一个事实，即您可以通过子类的实例交换类的实例，而Late Binding意味着当您调用实例的方法时，类型决定了将调用哪个方法(子类/超类).

I've seen both used interchangebly but do they really mean the same? From my understanding, Polymorphism stretches the fact that you could exchange an instance of a class by an instance of a subclass, and Late Binding means that when you call a method of an instance, the type decides which method (subclass/superclass) gets called.

推荐答案

维基百科上有一篇很好的文章:

Wikipedia has a very nice article about this:

摘要:后期绑定是一种实现多态的方法.

Summary: Late binding is a way to implement polymorphism.
