@[TOC](6-1 sdust-Java-模拟主板、USB口、TypeC口、PS2口设备 (30 分))

题目描述

使用Java编码设计实现模拟计算机硬件中的主板、USB口、TypeC口、PS2口及其组合方式。通常，计算机主板中提供了各种不同类型的对外接口，可以对接不同类型的设备。例如，可以接USB口的U盘、鼠标等，可以接口TypeC口的鼠标、键盘，可以接PS2口的键盘。要求：通过下面Main类中main方法给出的代码及其注释，设计相关的类、抽象类或接口（具体需要的类、接口或抽象类，根据程序样例给出的代码和注释来编写），使得main方法中的代码能够正确运行，且能够实现样例所示的输入输出功能。

Main类的main方法测试程序样例：

import java.util.Scanner;
public class Main{
  public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    String mainBoardModel = scan.next();//用户输入主板的型号
    String mousePS2Model = scan.next();//用户输入PS2口鼠标的型号
    String keyBoardPS2Model = scan.next();//用户输入PS2口键盘的型号
    String flashDiskModel = scan.next();//用户输入U盘的型号
    
    MainBoard mainboard = new MainBoard(mainBoardModel);//生成主板对象
    
    KeyBoardPS2 keyboard = new KeyBoardPS2(keyBoardPS2Model);//生成PS2口键盘对象
    mainboard.setPs2(keyboard);//将键盘接入主板的PS2口
    mainboard.inputFromPS2();//获取从键盘录入的数据（注意：是模拟从键盘录入数据，不需要编码利用Scanner接收数据）
    mainboard.setPs2(null);//拔出PS2口键盘
    
    MousePS2 mouse = new MousePS2(mousePS2Model);//生成PS2口的鼠标对象
    mainboard.setPs2(mouse);//将鼠标接入主板的PS2口
    mainboard.inputFromPS2();//获取从键盘录入的数据
    //
    FlashDisk flashdisk = new FlashDisk(flashDiskModel);//生成U盘对象
    mainboard.setUsb(flashdisk);//在主板上插入U盘的USB口
    mainboard.read();//从外接设备（USB或TypeC口设备上读取数据，只要接入相关设备，则从该设备读取数据）
    mainboard.setUsb(null);//拔下U盘：flashdisk
    
    mainboard.setTypeC(flashdisk);//将U盘：flashdisk插入主板的TypeC口（FlashDisk的对象同时支持USB和TypeC口）
    mainboard.read();//从外接设备（USB或TypeC口设备上读取数据，只要接入相关设备，则从该设备读取数据）
    
    MouseUSB mouseUSB = new MouseUSB();//生成USB鼠标
    mainboard.setUsb(mouseUSB);//在主板上插入USB鼠标的USB口
    
      scan.close();
  }
}
