设计模式十二.docx

1、设计模式十二一实验目的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Address中，用浅克隆和

2、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.javapackage 设计模式实验十二周_1;pu
