前几天加班太狠了今天调休一天，睡到下午醒了没什么事就写了一个这样的小玩意儿。
大佬看到之后不要把我拉到黑名单里，本人没有任何摸鱼行为，工作认真负责，能够高强度连续加班。（滑稽）
<>先上效果：
<>前一阵子收到微信群里的一条消息如下：
<>心想：嗯？！这玩意儿我为啥不做一个呢？
着手开始准备：
结构：
<>假期对象：Holiday
package eneity; import java.util.Date; public class Holiday { private String
type; private Date dateDay; public String getType() { return type; } public void
setType(String type) { this.type = type; } public Date getDateDay() { return
dateDay; } public void setDateDay(Date dateDay) { this.dateDay = dateDay; }
public Holiday(String type, Date dateDay) { this.type = type; this.dateDay =
dateDay; } }
