@[TOC](6-1 sdust-Java-模擬主板、USB口、TypeC口、PS2口設備 (30 分))

題目描述

使用Java編碼設計實現模擬計算機硬件中的主板、USB口、TypeC口、PS2口及其組合方式。通常，計算機主板中提供了各種不同類型的對外接口，可以對接不同類型的設備。例如，可以接USB口的U盤、鼠標等，可以接口TypeC口的鼠標、鍵盤，可以接PS2口的鍵盤。要求：通過下面Main類中main方法給出的代碼及其註釋，設計相關的類、抽象類或接口（具體需要的類、接口或抽象類，根據程序樣例給出的代碼和註釋來編寫），使得main方法中的代碼能夠正確運行，且能夠實現樣例所示的輸入輸出功能。

Main類的main方法測試程序樣例：

import java.util.Scanner;
public class Main{
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		String mainBoardModel = scan.next();//用戶輸入主板的型號
		String mousePS2Model = scan.next();//用戶輸入PS2口鼠標的型號
		String keyBoardPS2Model = scan.next();//用戶輸入PS2口鍵盤的型號
		String flashDiskModel = scan.next();//用戶輸入U盤的型號
		
		MainBoard mainboard = new MainBoard(mainBoardModel);//生成主板對象
		
		KeyBoardPS2 keyboard = new KeyBoardPS2(keyBoardPS2Model);//生成PS2口鍵盤對象
		mainboard.setPs2(keyboard);//將鍵盤接入主板的PS2口
		mainboard.inputFromPS2();//獲取從鍵盤錄入的數據（注意：是模擬從鍵盤錄入數據，不需要編碼利用Scanner接收數據）
		mainboard.setPs2(null);//拔出PS2口鍵盤
		
		MousePS2 mouse = new MousePS2(mousePS2Model);//生成PS2口的鼠標對象
		mainboard.setPs2(mouse);//將鼠標接入主板的PS2口
		mainboard.inputFromPS2();//獲取從鍵盤錄入的數據
		//////////////////////////////////////////////////////////
		FlashDisk flashdisk = new FlashDisk(flashDiskModel);//生成U盤對象
		mainboard.setUsb(flashdisk);//在主板上插入U盤的USB口
		mainboard.read();//從外接設備（USB或TypeC口設備上讀取數據，只要接入相關設備，則從該設備讀取數據）
		mainboard.setUsb(null);//拔下U盤：flashdisk
		
		mainboard.setTypeC(flashdisk);//將U盤：flashdisk插入主板的TypeC口（FlashDisk的對象同時支持USB和TypeC口）
		mainboard.read();//從外接設備（USB或TypeC口設備上讀取數據，只要接入相關設備，則從該設備讀取數據）
		
		MouseUSB mouseUSB = new MouseUSB();//生成USB鼠標
		mainboard.setUsb(mouseUSB);//在主板上插入USB鼠標的USB口
		
	    scan.close();
	}
}
