1.外部类使用外部类中的内部类

public class Outer {   int some_member;   abstract class InnerBase {    abstract void method();   } }  class OuterExtendsInner extends Outer.InnerBase {  Outer ou = null  ;public OuterExtendsInner(Outer o) {o.super();this.ou = o ;    }  void method() {   int x = ou.some_member ;// do some thing with some_member ;}  }
