java - 嵌套类和成员类是一回事吗？

Question

Java 术语嵌套类和成员类可以互换使用吗？

来自 JLS:

A nested class is any class whose declaration occurs within the body of another class or interface.

[…]

A member class is a class whose declaration is directly enclosed in the body of another class or interface declaration

我认为成员类一词可能不包括匿名类和本地类，但这只是我的猜测。

这是 Chapter 8. Classes 的一段很好的引用。 :

Member class declarations describe nested classes that are members of the surrounding class. Member classes may be static, in which case they have no access to the instance variables of the surrounding class; or they may be inner classes.

作为奖励报价，local classes绝对不是成员类:

A local class is a nested class that is not a member of any class [...].

class Foo {
    // a member class
    class InstanceMember {}
    // a member class
    static class StaticMember {}

    Foo() {
        // not a member class
        class LocalAndNotMember {}
        // not a member class
        Object anonymousAndNotMember = new Object() {};
    }
}
