作业.用类描述计算机中CPU的速度和硬盘容量

package クラス;public class CPU {int speed;void getSpeed(int m) {speed=m;}int getSpeed() {return speed;}}

package クラス;public class HardDisk {int  amount;void getAmount(int m) {amount=m;}int getamount() {return amount;}}

package クラス;public class PC {CPU cpu;void setCPU(CPU c) {cpu=c;}HardDisk HD;void setHradDisk(HardDisk h) {HD=h;}void show() {System.out.printf("CPUスピード："+cpu.getSpeed()+"ハードデスク容量"+HD.amount);}}

package クラス;public class Test {public static void main(String[] args) {CPU cpu=new CPU();cpu.speed=2000;HardDisk disk=new HardDisk();disk.amount=200;PC pc=new PC();pc.setCPU(cpu);pc.setHradDisk(disk);pc.show();}}
