枚举应用三

枚举实现的接口

 1 package com.yeepay.sxf.euma;
 2 /**
 3  * 枚举接口类
 4  * @author sxf
 5  *
 6  */
 7 public interface SuprtEuma {
 8     /**
 9      * 输入值获取当前枚举的字符串
10      * @param integer
11      * @return
12      */
13     public String getIndex(Integer integer);
14 }

枚举类

 1 package com.yeepay.sxf.euma;

10     SXF("尚晓飞",27),
11     QCF("瞿成峰",28);

13     private String name;
14     private Integer age;

18         this.age=age;
19     }

24     @Override
25     public  String getIndex(Integer integer) {
26         Diest[] de=Diest.values();
27         for (Diest diest : de) {
28             Integer age=diest.getAge();
29             if(age==integer){
30                 return diest.getName();
31             }
32         }

40         this.name = name;
41     }
42     public Integer getAge() {
43         return age;

46         this.age = age;

枚举测试类

 1 package com.yeepay.sxf.euma;
 2
 3
 4 public class Test {
 5     public static void main(String[] args) {
 6         test3();
 7     }
 8
 9     public static void test3(){
10         String nameString=Diest.HSL.getIndex(26);
11         System.out.println("Test.test3()"+nameString);
12     }
13
14 }
