Car接口以及两个实现类
//第一种实现
public class CarFactory {
public static Car createCar(String type){
if("奥迪".equals(type)){
return new Audi();
}else if("比亚迪".equals(type)){
return new Byd();
}else{
return null;
}
}
}
//第二种实现
public class CarFactory2 {
public static Car createAudi(){
return new Audi();
}
public static Car createByd(){
return new Byd();
}
}
工厂类实现
/**
* 普通模式，无工厂模式

public class Client01 {
public static void main(String[] args) {
Car c1 = new Audi();
Car c2 = new Byd();
c1.run();
c2.run();
