Objects, Attributes, Methods and Encapsulation An object is something that is or is capable of been seen, touched, or otherwise sensed, and about which users store data and associate behavior. 1、对象，属性，方法和封装 对象是能看得见、摸得着或感觉到的某种事物，并且存放数据和与之有关的行为。 10.1 What Is OO?- system concepts for object modeling With advances in technology, attributes have involved to include more than simple data characteristics as represented in the previous examples. 随着技术的发展，对象的属性不仅仅包括前面例子中表示的那些简单的数据特征。 10.1 What Is OO?- system concepts for object modeling Encapsulation is then the technique for packaging the information in such a way as to hide what should be hidden, and make visible what is intended to be visible. 封装是一种将应该隐藏的信息隐藏起来，将应该可见的信息是可见的方式的包装技术。 10.1 What Is OO?- system concepts for object modeling 2.
