内在的阶级延伸 [英] inner class extending

问题描述

在java中，假设我有以下类：

In java, say I have the following class:

public class A{
  protected class B{
  }
}

我可以通过执行以下操作来扩展内部类吗？ / p>

can I extend the inner class by doing the following?

public class C extends A{
  protected class D extends B{
  }
}

我想做的是我上面有C级，我需要在A的内部改变一些东西所以我认为我需要扩展内部类来这样做，但我不确定如何做到这一点。

What I want to do is that I have the class C above and I need to change something in A's inner class so I was thinking that I need to extend the inner class to do so but I wasn't sure how exactly to do that.
