1、精选优质文档-倾情为你奉上一、抽象工厂模式1.1 题目：计算机包含内存（RAM）、CPU等硬件设备，根据下面的“产品等级结构-产品族”示意图，使用抽象工厂模式实现计算机设备创建过程并绘制相应的类图。1.2类图：1.3程序代码：/定义接口CPUpublic interface CPU void create();/定义接口RAMpublic interface RAM void create();/定义类PcCPUpublic class PcCPU implements CPUpublic void create() System.out.println( win cpu);/定义类PcRAM

2、public class PcRAM implements RAM public void create() System.out.println(win RAM);/定义类MacCPUpublic class MacCPU implements CPUpublic void create() System.out.println(mac CPU);/定义类MacRAMpublic class MacRAM implements RAMpublic void create() System.out.println(mac RAM);/定义接口ComputerFactoryinterface C

3、omputerFactory CPU produceCPU();RAM produceRAM();/定义类ComputerPartsClientpublic class ComputerPartsClient public static void main(String args) ComputerFactory factory;CPU cpu;RAM ram; factory = new PcFactory();cpu = duceCPU();cpu.create();ram = duceRAM();ram.create();ComputerFac

4、tory factory1;factory1 = new MacFactory();cpu = duceCPU();cpu.create();ram = duceRAM();ram.create();/定义类PcFactorypublic class PcFactory implements ComputerFactory public PcCPU produceCPU() System.out.println(请使用PC产品族的CPU);return new PcCPU();public PcRAM produceRAM() System.ou

5、t.println(请使用PC产品族的RAM);return new PcRAM();/定义类MacFactorypublic class MacFactory implements ComputerFactorypublic MacCPU produceCPU() System.out.println(请使用Mac产品族的CPU);return new MacCPU();public MacRAM produceRAM() System.out.println(请使用Mac产品族的RAM);return new MacRAM();1.4运行结果：二、桥接模式2.1题目：如果系统中某对象有三个

6、维度，如某日志记录器既可以支持不同的操作系统（Windows、Linux、Unix），还可以支持多种编程语言（C#、C+、Java），并且可以使用不同的输出方式（File、Console、XML）。请使用桥接模式设计该系统。2.2类图：2.3程序代码：定义类Languagepublic abstract class Language protected Logger log;public void setLogger(Logger log) this.log = log;public abstract void writeLog();定义类 Cpublic class C extends La

7、nguage public void writeLog()System.out.println(用C开发该系统);this.log.outwork();定义类 Javapublic class Java extends Language public void writeLog()System.out.println(用JAVA开发该系统);this.log.outwork();定义类CAApublic class CAA extends Languagepublic void writeLog()System.out.println(用C+开发该系统);this.log.outwork();

8、定义类Operationpublic abstract class Operation protected Language language;public void setLanguage(Language language) this.language = language;public abstract void writeLanguageVersion();定义类Windowspublic class Windows extends Operationpublic void writeLanguageVersion() System.out.println(基于Windows操作系统！

9、);this.language.writeLog();定义类Linuxpublic class Linux extends Operationpublic void writeLanguageVersion() System.out.println(基于Linux操作系统！);this.language.writeLog();定义类Unixpublic class Unix extends Operationpublic void writeLanguageVersion() System.out.println(基于Unix操作系统！);this.language.writeLog();定义

10、接口Loggerpublic interface Logger public void outwork();定义类ConsoleLoggerpublic class ConsoleLogger implements Loggerpublic void outwork() System.out.println(输出流到控制台日志完成);定义类FileLoggerpublic class FileLogger implements Loggerpublic void outwork() System.out.println(输出流到文件日志完成);定义类Clientpublic class Cli

11、ent public static void main(String args) Logger filelog = new FileLogger();Logger consolelog = new ConsoleLogger();Language java = new Java();java.setLogger(filelog);Language caa = new CAA();caa.setLogger(consolelog);Language c = new C();c.setLogger(consolelog);Operation windows = new Windows();windows.setLanguage(caa);windows.writeLanguageVersion();System.out.println(*);Operation linux = n
