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 ;
	}  
}
