 1 package test_16_3;
 2 
 3 public class Outter {
 4 
 5     public Inter inter() {
 6         return new Inter() {
 7             
 8             
 9             
10             @Override
11             public String show() {
12                 System.out.println("show");
13                 
14                 return "this is Outter.Inner.show()";
15             }
16         };
17     }
18     
19     public static void main(String[] args) {
20         
21         Outter outter = new Outter();
22         Inter inter = outter.inter();
23         System.out.println(inter.show());
24     }
25 }

 

结果如下：

show
this is Outter.Inner.show()
