Java 枚举 封装 错误代码

enum Read_Card_Msg {  
      TIME_OUT("msg1",1000)
      ,FORMAT_ERROR("msg2",10001)
      ,Not_FIND_CARD("msg3",1002)
      ,FIND_CARD_OK("msg4",1002);
      private String msg;
      private int msg_id;
      private Read_Card_Msg(String msg,int msg_id)
      {
          this.msg=msg;
          this.msg_id=msg_id;
      }
      public String getMsg()
      {
          return this.msg;
      }
      public int getMsg_id() {
        return this.msg_id;
    }
}

使用时

Read_Card_Msg.FIND_CARD_OK.getMsg_id();

Read_Card_Msg.FIND_CARD_OK.getMsg();
