java基础之：匿名内部类应用例子一

一：接口

 package com.yeepay.sxf.testclassforinner;

 /**
  * 回调接口.
  * @author shangxiaofei
  *
  */
 public interface CallBack {

     public boolean process(Integer a);

     public boolean delete(Integer b);
 }

二：业务类

 package com.yeepay.sxf.testclassforinner;
 /**
  * 业务类使用回调接口
  * @author shangxiaofei
  *
  */
 public class PayMentService {

     public String payforMoney(Integer a,CallBack callBack){
         System.out.println("PayMentService.payforMoney()"+a);
         Integer m=a+100;
         if(m>100){
             boolean falg=callBack.process(m);
             if(falg){
                 return "callBack.process"+m;
             }else{
                 return "callBack.process"+m;
             }

         }else{
             boolean flag=callBack.delete(m);
             if(flag){
                 return "callBack.delete"+m;
             }else{
                 return "callBack.delete"+m;
             }
         }
     }
 }

三：控制类

 package com.yeepay.sxf.testclassforinner;
 /**
  * 测试类
  * @author shangxiaofei
  *
  */
 public class TestController {

     private PayMentService payMentService=new PayMentService();

     private String dd="sxf";

     public void testPay(){

         String aString=payMentService.payforMoney(100, new CallBack() {

             @Override
             public boolean process(Integer a) {
                 String mString="";
                 if(a>100){
                     mString="sxf";
                 }
                 if(mString.equals(dd)){
                     return true;
                 }
                 return false;
             }

             @Override
             public boolean delete(Integer b) {
                 String mString="";
                 if(b<100){
                     mString="sxf";
                 }
                 if(mString.equals(dd)){
                     return true;
                 }
                 return false;
             }
         });

         System.out.println("enclosing_type.enclosing_method()"+aString);
     }

     public static void main(String[] args) {
         TestController controller=new TestController();
         controller.testPay();
     }
 }
