来自JDK，JRE的内部，嵌套，本地和匿名类的示例

Question

I find a very useful to read this question: Java inner class and static nested class , but can't find there any example from Java. Could you provide me with real examples of using those classes from JDK, JRE?

Answer 1

Nested classes (static inner) do not have a reference to outer context. Map#Entry is an example of such nested class -- it contains only key, value pair properties and by definition has no access to outer Map implementation.
