为什么我们不能有静态外部类 [英] Why can't we have static outer classes

问题描述

为什么我们不能创建外部的静态类。我在这个社区读到了问题的答案，但我还没有得到完美答案。有些人可以帮我一个确切的答案

Why can't we create static classes which are outer. I read answers to the question in this community but I haven't gotten a perfect answer. Can some help me with an exact answer

   static class A
    {  
        void display()
        {
            System.out.println("This is a static class");  
        }

    }

推荐答案

外部类已经有效 static A static 嵌套类意味着它没有引用外部类。外部类已经没有对另一个类的隐式引用。

Outer classes are already effectively static A static nested class means it has no reference to the outer class. An outer class already has no implicit reference to another class.
