与显式类装入一样，如果类已经装入了，那么只是返回一个引用；否则，装入器会通过委托模型装入类。
As with explicit class loading, if the class is already loaded, then a reference is simply returned; otherwise, the loader goes through the delegation model to load the class.

隐式类装入发生在由于引用、实例化或继承导致装入类的时候(不是通过显式方法调用)。
Implicit class loading occurs when a class is loaded as result of a reference, instantiation, or inheritance (not via an explicit method call).
所有数据引用都显式表明每个节点上的名称空间，避免在允许默认名称空间(其中不使用前缀)时可能产生的混乱。
All references to data explicitly state the namespace at each node, avoiding confusion that can arise when allowing the default namespace, where no prefix is used.
例如，类装入器可能先显式地装入一个类，然后再隐式地装入它引用的所有类。
For example, a class loader could first load a class explicitly and then load all of its referenced classes implicitly.
