一起学Java设计模式--抽象工厂方法模式(创建型模式)

抽象工厂模式

电脑配件生产工厂生产内存、CPU等硬件设备，这些内存、CPU的品牌、型号并不一定相同，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电脑配件生产过程并绘制相应的类图，绘制类图并编程实现。

UML类图：

interface CPU{void discribe();}interface RAM{  void discribe();}class PcCPU implements CPU{public void discribe(){System.out.println("This is produce the PC_CPU ^_^");　　}}class MacCPU implements CPU{public void discribe(){System.out.println("This is produce the Mac_CPU ^-^");}}class PcRAM implements RAM{public void discribe(){System.out.println("PcRAM");}}class MacRAM implements RAM{public void discribe(){System.out.println("MacRAM");}}interface  ComputerPartsFactory{ CPU produceCPU();ARM produceARM();} public class PcFactory implements ComputerPartsFactory { public PcCPU produceCPU() {System.out.println("PC_CPU produced! >_<");return new PcCPU(); public PcRAM produceRAM() {System.out.println("PC_ARM produced! >_<");return new PcARM();}}public class MacFactory implements ComputerPartsFactory{ public MacCPU produceCPU() {System.out.println("MacCPU produced! ~_~");return new MacCPU();} public MacRAM produceRAM() {System.out.println("MacARM produced! ~_~");return new MacARM();}}class ComputerPartsClient{public static void main(String a[]){CPU cpu;ARM arm;ComputerPartsFactory pcFactory;ComputerPartsFactory macFactory;System.out.println("THIS IS THE PC_PARTS 0_0");pcFactory = new PcFactory();cpu = pcFactory.produceCPU();arm = pcFactory.produceARM();cpu.discribe();arm.discribe();System.out.println("***************************");System.out.println("THIS IS THE MAC_PARTS 0_0");macFactory = new MacFactory();cpu = macFactory.produceCPU();arm = macFactory.produceARM();cpu.discribe();arm.discribe();}}

运行结果：
