Java-用类描述计算机中CPU的速度和硬盘容量

主类Text

public class Text {
	public static void main(String args[]){
		//创建一个CPU对象
		CPU cpu =new CPU();
		//将cpu的speed设置为2200
		cpu.setSpeed(2200);
		//创建一个HardDisk对象
		HardDisk disk=new HardDisk();
		//将disk的amount设置为200
		disk.setAmount(200);
		//创建一个PC对象
		PC pc=new PC();
		pc.setCPU(cpu);
		pc.setHardDisk(disk);
		pc.show();
		
	}

}

CPU类

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

}

HardDisk类

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

}

PC类

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