Java之枚举举例

 package enumdemo;

 /**
  * 枚举类
  */

 public enum MAPPER {

     // 实例
     ELEMENT_NAME("mapper"),
     ATTRIBUTE_RESOURCE("resource");

     private String content;

     MAPPER(String content) {
         this.content = content;
     }

     public String getContent() {
         return content;
     }

     public void setContent(String content) {
         this.content = content;
     }
 }

 package enumdemo;

 /**
  * 枚举测试
  */
 public class Test {
     public static void main(String[] args) {
         String content = "";
         content = MAPPER.ATTRIBUTE_RESOURCE.getContent();
         System.out.println(content);

         String content2 = MAPPER.valueOf("ELEMENT_NAME").getContent();
         System.out.println(content2);

         for (MAPPER mapper : MAPPER.values()) {
             System.out.println(mapper.getContent());
         }
     }
 }

运行结果：

resource
mapper
mapper
resource
