设计模式第二次作业
一：职责链模式
题目（PPT上的题目）：某OA系统需要提供一个假条审批的模块，如果员工请假天数小于3
天，主任可以审批该假条；如果员工请假天数大于等于3天，小于10天，经理可以审批；如果
员工请假天数大于等于10天，小于30天，总经理可以审批；如果超过30 天，总经理也不能审
批，提示相应的拒绝信息。（UML图如下）请写出java源码

二：享元模式
题目(课上PPT题目修改)：实例一：共享网络设备(无外部状态)很多网络设备都是支持共享
的，如手机，电脑可以开热点(HOt),路由器(Modem)也可实现共享网络，并通过该该设备进
行数据转发，如图所示，现用四年级历史人物故事200字享元模式模拟共享网络设备的设计原理。解答：UML图如

DeviceFactory
-devices : ArrayList = new MayLiSt()
-totaTerminal : int = O
+ DeviceFactory O
+ QetNetworkDevice (String type)
+ getT OtaIDevice O

A NetworkDevice

.抽象享元类NetworkDevice (网络设备类)
public interface NetWorkDevice
(
private Stri秦国国君顺序 ng getType();
public viod use();

2 .具体享元类(路由器类)
Modem
public class Modem implements NetworkDevice
