cpu速度和硬盘容量

public class CPU {int speed;public int getSpeed(){int sp;sp=this.speed;return sp;}public void setSpeed(int m){this.speed=m;}}

public class HardDisk {int amount;public int getAmount(){int am;am=this.amount;return am;}public void setAmount(int m){this.amount=m;}}

public class PC {CPU cpu = new CPU();HardDisk HD = new HardDisk();public void setCPU(CPU c){this.cpu=c;}public void setHardDisk(HardDisk h){this.HD=h;}public void show(){System.out.println("CPU速度："+cpu.getSpeed());System.out.println("硬盘容量："+HD.getAmount());}}

public class Test {/** * @param args */public static void main(String[] args) {//CPU cpu = new CPU();cpu.setSpeed(2200);HardDisk disk = new HardDisk();disk.setAmount(200);PC pc = new PC();pc.setCPU(cpu);pc.setHardDisk(disk);pc.show();}}
