計算機硬件接口類：

/*** @author Administrator* CPU接口*/ public interface CPU {public String getBand();public String getZhuPin(); }/*** @author Administrator* 內存接口*/ public interface Dimm {public String dimmSize(); }/*** @author Administrator* 硬盤接口*/ public interface SD {public String sdSize(); }

硬件生產商類：

/*** @author Administrator* CPU生產商*/ public class CPUpro implements CPU{public String getBand() {return "Intel"; }public String getZhuPin() {return "3.8GHz"; }}/*** @author Administrator* 內存生產商*/ public class DimmPro implements Dimm{@Overridepublic String dimmSize() {// TODO Auto-generated method stubreturn "4GB";}}/*** @author Administrator* 硬盤生產商*/ public class SDpro implements SD{@Overridepublic String sdSize() {return "3000GB";} }

計算機類：

/*** @author Administrator* 計算機類*/ public class Computer {private CPU cpu;private SD sd;private Dimm dimm;public Computer() {}public Computer(CPU cpu, SD sd, Dimm dimm) {super();this.cpu = cpu;this.sd = sd;this.dimm = dimm;}public void print() {System.out.println("計算機的信息如下：");System.out.println("CPU的品牌是："+cpu.getBand()+",主頻是："+cpu.getZhuPin());System.out.println("硬盤容量是："+sd.sdSize());System.out.println("內存容量是："+dimm.dimmSize());}public CPU getCpu() {return cpu;}public void setCpu(CPU cpu) {this.cpu = cpu;}public SD getSd() {return sd;}public void setSd(SD sd) {this.sd = sd;}public Dimm getDimm() {return dimm;}public void setDimm(Dimm dimm) {this.dimm = dimm;}}

測試類：

public class Text {public static void main(String[] args) {CPU cpu = new CPUpro();SD sd = new SDpro();Dimm dimm = new DimmPro();Computer computer = new Computer(cpu,sd,dimm);computer.print();} }
