大家应该都去麦当劳或肯德基吃过快餐，参考肯德基官网的信息模拟肯德基快餐店的收银系统，简单的java Gui模拟的肯德基收银系统。

1.系统介绍

同学们应该都去麦当劳或肯德基吃过快餐吧？请同学们参考肯德基官网的信息模拟肯德基快餐店的收银系统，合理使用C++/python/Java,结合设计模式（2种以上）至少实现系统的以下功能：

1.正常餐品结算和找零。

2.基本套餐结算和找零。

3.使用优惠劵购买餐品结算和找零。

4.可在一定时间段参与店内活动（自行设计或参考官网信息）。

5.模拟打印小票的功能（写到文件中）。

2.系统设计

1.界面设计

采用java的Gui实现简单的界面布局,界面上主要是图片和数据的显示.我大多采用的是BorderLayout布局的方式,然后设置每个方位的大小.界面就很快做出来了.

小票信息截图:

2.后台设计

采用了抽象工厂模式和策略模式设计餐品的创建.

3.主要源代码

主界面:
