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;

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

public class PC {
	CPU cpu = new CPU();

		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 {
