多态性概念:

在程序中同一符号或名字在不同情况下具有不同的语义解释,其有两种基本形式:



编译时多态性:

在程序编译时可确定的多态性,由重载机制实现

运行时多态性:

指程序动态运行时才可确定的多态性,由继承结合动态绑定实现.

-Polymorphism of the concept: in the proceedings or the names of the same symbols in different situations have different semantic interpretation, which comes in two basic forms: compile-time polymorphism: In the procedure compile-time polymorphism can be identified by the heavy-duty mechanism to achieve run-time polymorphism: means the process will be required to determine the dynamic run-time polymorphism, dynamic binding by the combination of the realization of the succession.
