设计模式十二

1、实验目的1. 熟悉 UML 统一建模语言；2. 回顾熟悉建造模式、原型模式；3. 熟悉 XML 文件的操作；4. 熟悉 java 的反射机制。二实验内容（1）某软件公司欲开发一个音频和视频播放软件，为了给用户使用提供方便，该播放软件 提供了多种界面显示模式，如完整模式、精简模式、记忆模式、网络模式等。在不同的显示 模式下主界面的组成元素有所差异， 如在完整模式下将显示菜单、 播放列表、主窗口、 控制 条等， 在精简模式下只显示主窗口和控制条， 而在记忆模式下将显示主窗口、控制条、 收藏 列表等。现使用建造者模式设计该软件。（ 2）设计一个客户类 Customer，其中客户地址存储在地址类Add

2、ress 中，用浅克隆和深克隆分别实现 Customer 对象的复制并比较这两种克隆方式的异同。三实验环境PC 微机；Windows 操作系统；Visual Studio 程序集成环境。四实验内容（1） 某软件公司欲开发一个音频和视频播放软件， 为了给用户使用提供方便， 该播放软件提供 了多种界面显示模式，如完整模式、精简模式、记忆模式、网络模式等。在不同的显示模式 下主界面的组成元素有所差异， 如在完整模式下将显示菜单、 播放列表、 主窗口、控制条等， 在精简模式下只显示主窗口和控制条， 而在记忆模式下将显示主窗口、 控制条、收藏列表等。 现使用建造者模式设计该软件。ModelBuilder
