Java：一个类本身是一个子类吗？ [英] Java: Is a class a subclass of itself?

问题描述

一个类可以是一个子类，如果它的内部类扩展外部类
所以该类不知何故扩展自己没有抛出任何异常。

A class can be a "subclass" of itself if its inner class extend the outer class so the class is somehow extending itself without throwing any Exception. So, does it really mean a class is also a subclass of itself?

谢谢。

推荐答案

类不是自身的子类。内部类可以是某个其他类的子类，但这是一个单独的类。你可以通过比较调用getClass（）时获得的类实例来验证这一点。

A class is not a subclass of itself. An inner class could be a subclass of some other class, but that is a separate class. You can verify this by comparing the Class instances you get when you call getClass().
