项目三(2)——简单工厂模式

请采用采用简单工厂设计模式，为某个汽车销售店设计汽车销售系统，接口car至少有方法print（），三个汽车类：宝马、奥迪、大众 （属性：品牌，价格），在测试类中根据客户要求购买的汽车品牌，通过接口car为客户提供相应的汽车对象。

package pro4;

public class Car01 {
	public static void main(String[] args) { 
		Car c1=null;
		c1=Factory.getInstance("Audi");
		if(c1!=null){
			c1.print();
		}
	}
}
interface Car{
	public void print();
}
class Factory{
	public static Car getInstance(String name){
		Car c1=null;
		if("BMW".equals(name)){
			c1=new BMW("BMW 740Li",1200000);
		}
		if("Audi".equals(name)){
			c1=new Audi("Audi A8",1000000);
		}
		if("VW".equals(name)){
			c1=new VW("Volkswagen Pharton",1888888);
		}
		return c1;
	}
}
class BMW implements Car{
	private String name;
	private double money;
	public BMW(String name,double money){

	public void setMoney(double money) {
