1、第5次实验张超红抽象工厂方法设计模式实验实验五抽象工厂方法设计模式专业：软件工程 班级：java2班 实验日期：2015年 3 月 14 日 报告退发 (订正 、 重做) 学号：123012012137 姓名：张超红实验目的：加深对抽象工厂方法设计模式及创建型设计模式原理的理解实验环境：C#.Net/VC+.Net或MyEclipse(Java)等实验内容： 某单据管理系统中要求实现对采购、销售、库存的单据管理，系统的采购类的单据中有如采购单、收货单、应付帐单、付款单和退货单等，现使用抽象工厂方法设计模式设计该系统。实验过程：1、构建实现场景，给出需求中的问题描述2、画出UML类图 3、实现代
