摘　　要：多态性是面向对象程序设计的重要特性,动态多态性是一种在运行时,而不是在编译时进行的动态绑定机制,它的基础是动态方法调用。深入讨论了在单继承的情况下C++和Java编程语言的动态绑定机制,这有助于理解面向对象程序设计思想。Polymorphism is an important object-oriented programming features, dynamic polymorphism is running, rather than at compile time dynamic binding mechanism, which is based on the dynamic method invocation. This paper discussed on in depth in the case of single inheritance C ＋＋ and Java programming language dynamic binding mechanism, which helps to understand obiect-oriented programming.

关 键 词：面向对象程序设计 虚函数 动态多态性 动态方法调用
