Java之枚举举例

 1 package enumdemo;
 2 
 3 /**
 4  * 枚举类
 5  */
 6 
 7 public enum MAPPER {
 8 
 9     // 实例
10     ELEMENT_NAME("mapper"),
11     ATTRIBUTE_RESOURCE("resource");
12 
13     private String content;
14 
15     MAPPER(String content) {
16         this.content = content;
17     }
18 
19     public String getContent() {
20         return content;
21     }
22 
23     public void setContent(String content) {
24         this.content = content;
25     }
26 }

 1 package enumdemo;
 2 
 3 /**
 4  * 枚举测试
 5  */
 6 public class Test {
 7     public static void main(String[] args) {
 8         String content = "";
 9         content = MAPPER.ATTRIBUTE_RESOURCE.getContent();
10         System.out.println(content);
11 
12         String content2 = MAPPER.valueOf("ELEMENT_NAME").getContent();
13         System.out.println(content2);
14 
15         for (MAPPER mapper : MAPPER.values()) {
16             System.out.println(mapper.getContent());
17         }
18     }
19 }

运行结果：

resource
mapper
mapper
resource
