一种优秀的放置枚举的编码方式

package com.XXX.enums;public class EnumsUtil {    public enum Demo1 {        FIRST;    }    public enum Demo2 {        TWO;    }    public enum Demo3 {        THREE;    }    public static void main(String[] args) {        System.out.println(Demo1.FIRST);        System.out.println(Demo2.TWO);        System.out.println(Demo3.THREE);    }}
