云南大学软件学院抽象工厂模式.doc

云南大学软件学院实 验 报 告序号： 姓名： 学号： 专业： 日期： 成绩： 实验三 抽象工厂模式的运用一、实验目的：抽象工厂模式提供一个接口，用于创建相关或依赖对象的家族，而不需要明确指定具体类。在熟悉抽象工厂模式相关理论知识的基础上，使用抽象工厂模式实现“电脑配置商店”程序。二、实验要求：使用抽象工厂模式实现“电脑配置商店”，要求如下：1. 电脑由CPU、主板、显卡、内存、硬盘等配件组合而成。现电脑配置有两种配置方案。2. 根据配置方案可以显示具体配置信息。3. 根据配置方案可以显示价格。1、 设计并绘制该程序的类图；2、 依照设计的类图使用Java语言编写代码，并实现该程序；3、 除了核心的模式相关类实现外，提供测试环境，按照难度高低，分别是：a) 控制台程序，Client硬编码初始化模式和测试环境，运行结果文本输出；b) 控制台程序，Client初始化测试环境，并根据用户输入运算，运行结果文本输出；c) 设计并实现用户UI，Client初始化测试环境，并根据用户在UI控件上的输入运算，运行结果文本输出；三、实验内容：类图：1.ComputerFactory接口public interface ComputerFactory public Cpu createCpu();public Mainboard createMainboard();public GraphicsCard createGraphicsCard();public Ram createRam();public Caliche createCaliche();public void displayPrice();2.
