外观模式
[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。
实验要求：
1. 提交类图；
2. 提交源代码；

public class Gj19Client {
public static void main(String[] args) {

gj19Mainframe.on();
System.out.println("电脑关闭....");
gj19Mainframe.off();
}
}
3. 注意编程规范。
