成绩：实验4 抽象工厂模式题目:使用抽象工厂模式实现一个 DIY电脑店，其中的电脑配置有三个种类：学生版、家庭装、豪华版。模式设计的UML类图：程序源代码：1）计算机配置工厂接口ComputerConfigurationFactory.java：public interface ComputerConfigurationFactory{public CpucreateCpu();public RamcreateRam();public MainboardcreateMainboard();public HarddiskcreateHarddisk();public DisplaycreateDisplay();}（2）计算机配置工厂接口的各个子类：publicclassStudentComputerConfigurationFactoryimplementsComputerConfigurationFactory{publicCpucreateCpu(){returnnewStudentCpu();}publicRamcreateRam(){returnnewStudentRam();}publicMainboardcreateMainboard(){returnnewStudentMainboard();}publicHarddiskcreateHarddisk(){returnnewStudentHarddisk();}publicDisplaycreateDisplay(){returnnewStudentDisplay();}}publicclassHomeComputerConfigurationFactoryimplementsComputerConfigurationFactory{publicCpucreateCpu(){returnnewHomeCpu();}publicRamcreateRam(){returnnewHomeRam();}publicMainboardcreateMainboard(){returnnewHomeMainboard();}publicHarddiskcreateHarddisk(){returnnewHomeHarddisk();}publicDisplaycreateDisplay(){returnnewHomeDisplay();}}public class DeluxeComputerConfigurationFactoryComputerConfigurationFactory
