Java的题 。创建CPU

创建CPU类，该类中包含speed变量getSpeed和setPeed方法。创建HardDisk类，该类中包合amount变量，getAmount和setAmount方法。创建PC类，该类中包含CPU和HardDisk类的引用，包含setCpu、setHardDisk和show方法，其中show方法用来输出CPU的速度和硬盘容量。在测试内中分别创建CPU和HardDisk类的对象，设置CPU的速度及硬盘的容量，最后通过show方法输出CPU的速度和硬盘的容量。

class CPU{
int speed;
int getSpeed(){
return speed;
}
void setSpeed(int m){
speed=m;
}
}
 
class HardDisk{
int amount;
int getAmount(){
return amount;
}
void setAmount(int m){
amount=m;
}
}
 
class PC{
HardDisk HD;
CPU cpu;
void setCPU(CPU c){
cpu=c;
}
void setHardDisk(HardDisk h){
HD=h;
}
void show(){
System.out.println("CPU的速度是"+cpu.getSpeed());
System.out.println("硬盘的容量是"+HD.getAmount());
}
}
 
public class Test{
public static void main(String args[]){
CPU cpu=new CPU();
HardDisk disk=new HardDisk();
cpu.setSpeed(2200);
disk.setAmount(200);
PC pc=new PC();
pc.setCPU(cpu);
pc.setHardDisk(disk);
pc.show();
}
}

如有帮助望采纳
cpu

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

HardDisk

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

pc

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("CPU的速度"+cpu.getSpeed());
        System.out.println("硬盘容量"+hardDisk.getAmount());
    }
}

test

public class TEST {
    public static void main(String[] args) {
        PC pc =new PC();
        CPU cpu=new CPU();
        cpu.setSpeed(100.0);
        HardDisk hardDisk=new HardDisk();
        hardDisk.setAmount(100.1);
        pc.setCpu(cpu);
        pc.setHardDisk(hardDisk);
        pc.show();
    }
}
