The practice of starting with Java's primitive types, in many textbooks on OO programming using Java, obfuscates, rather than illustrates, the OO paradigm. Why should one start a text focusing on teaching the OO paradigm by featuring the part of Java that is not object-oriented? Why, in ...
instanceof IdentityObject和instanceof PrimitiveObject可以测试对象是否具有 identity(类似地,可以通过Class使用反射的方式进行测试)。 IdentityObject和PrimitiveObject类型的变量可以分别存储具有和不具有 identity 的对象。 类型参数边界extends IdentityObject和extends PrimitiveObject可以用于分别限制类型参数对应的值必须具有或...
