软件体系结构：工厂模式和抽象工厂模式

简单工厂模式

有一个OEM制造商代理做HP笔记本电脑(Laptop)，后来该制造商得到了更多的品牌笔记本电脑的订单Acer，Lenovo，Dell，该OEM商发现，如果一次同时做很多个牌子的本本，有些不利于管理。利用工厂模式改善设计，用JAVA语言实现 (或C#控制台应用程序实现)该OEM制造商的工厂模式。绘制该模式的UML图。

Computer.java

package ComputerInterface;

public interface Computer {
	public void ComputerType();
}

ComputerFactory.java

package ComputerInterface;

public interface ComputerFactory {
	public Computer getComputerType();

Acer.java

package ComputerType;

import ComputerInterface.Computer;

public class Acer implements Computer{

	@Override
	public void ComputerType() {
		System.out.println("ACER");

抽象工厂模式

麦当劳（McDonalds）和肯德基（KFC）快餐店都经营汉堡（Hamburg）和可乐（Cole），用JAVA语言实现（C#控制台应用程序实现）这两个快餐店经营产品的抽象工厂模式。绘制该模式的UML图。
