对于嵌套类对封闭类成员的访问权限，我有些困惑.它与外部阶级有什么关系?

I'm a little confused as to what access a nested class has to the members of an enclosing class. What is the relationship it shares with the outer class?

推荐答案

嵌套类对封闭类没有任何其他类无法使用的特殊访问权限-它可以看到公共成员，等等.嵌套仅为嵌套类提供了有用的作用域定义机制，但没有更改其行为或功能.

The nested class does not have any special access to the enclosing class that would not be available to any other class - it can see public members, etc. The nesting only provides a useful scoping mechanism for nested class, but doesn't change its behavior or capabilities.
