Java PC

题目：

CPU类：

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

HardDisk类：

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

PC类：

public class PC {private CPU cpu;private HardDisk hardDisk;public void setCpu(CPU cpu) {this.cpu = cpu;}public void setHardDisk(HardDisk hardDisk) {this.hardDisk = hardDisk;}public void show(){System.out.println("cup的速度："+cpu.getSpeed()+",磁盘容量："+hardDisk.getAmount());}}

Test类：

public class Test {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();}}
