我最近正在读<<Object-Oriented Systems Analysis and Design using UML>>, 其中提到object-oriention中的对象有两个意思:1)对现实世界的抽象;2)软件实施的基础。前面各位提到的我想是第二个意思,而面向对象之所以不叫面向类,正是因为第一层意思。
Think twice before you answer "object"...Objects remain important to describe the execution of an O-O system. But the basic notion from which everything in object technology derives, is class... Objects are not the subject.
