[实验任务一]：计算机开启

在计算机主机(Mainframe)中，只需要按下主机的开机按钮(on())，即可调用其他硬件设备和软件的启动方法 ，如内存(Memory)的自检(check())、CPU的运行(run())、硬盘(HardDisk)的读取(read())、操作系统(OS)的载入(load())，如果某一过程发生错误则计算机启动失败。

 

 

 

 

package test12;
public class Client
{
public static void main(String[]args) {
MainFrame mainframe = new MainFrame();
mainframe.on();
}
}

package test12;
public class CPU {
public boolean run(){
System.out.println("CPU加载成功");
return true;
}
}

package test12;
public class HardDisk {
public boolean read(){
System.out.println("硬盘读入成功");
return true;
}
}

package test12;
public class MainFrame {
public Memory memory = new Memory();

private CPU cpu = new CPU();

private HardDisk hardDisk = new HardDisk();

private OS os = new OS();



public void on(){

memory.check();

cpu.run();

hardDisk.read();

os.load();

}

}

package test12;
public class Memory {
public boolean check(){
System.out.println("内存检查成功");
return true;
}
}

package test12;
public class OS {
public boolean load(){

return true;
}
