适配器模式-基本代码

 1 public class Adapter {
 2 
 3     public static void main(String[] args) {
 4         Target t = new Target();
 5         t.request();
 6         t = new Adapterr();
 7         t.request();
 8     }
 9 }
10 //原请求
11 class Target{
12     public void request() {
13         System.out.println("普通请求");
14     }
15 }
16 //适配后请求
17 class Adaptee{
18     public void request() {
19         System.out.println("特殊请求");
20     }
21 }
22 //适配器
23 class Adapterr extends Target{
24     private Adaptee a = new Adaptee();
25 
26     @Override
27     public void request() {
28         a.request();
29     }
30     
31 }
