俺六级过了已经过了3年了,从那就没有见过英语,而这个专业英语俺不太懂,俺在这里胡说一下看对不对:该类没有(OR不是)shaded(呵呵,你对这个查一下词典),因为它表示一个对象实例,而不是对象本身。:}}}(脸红!!!!)

我主要翻译不了shaded,好像是隐蔽的意思.但这里该怎么理解呢.
呵呵,你不看括号里的字就行了。
不知道是不是有不妥之处,望各位指正。
类 不是 有形的, 因为 类并非表示一个实体(实例)本身
object rather than an object itself.
,而是实体(实例)的抽象概括。建议rain11er (清风) 贴多这个之前的几句。
Objects vs. Classes
You probably noticed that the illustrations of objects and classes look very similar. And indeed, the difference between classes and objects is often the source of some confusion. In the real world, it's obvious that classes are not themselves the objects they describe: A blueprint of a bicycle is not a bicycle. However, it's a little more difficult to differentiate classes and objects in software. This is partially because software objects are merely electronic models of real-world objects or abstract concepts in the first place. But it's also because the term "object" is sometimes used to refer to both classes and instances.
不能理解的部分是:In the figures, the class is not shaded, because it represents a blueprint of an object rather than an object itself. In comparison, an object is shaded, indicating that the object exists and that you can use it.
