实现创建者和调用者分离
//车
class Car{
private double price;
private double type;
}
//奔驰
class Benchi extends Car{
....
}
//奥迪
class Aodi extends Car{
....
}
//汽车工厂
interface CarFactory{
public Car createCar();
}
//奔驰工厂
class BenchiFactory implements CarFactory{
@Override
public Car createCar() {
System.out.println("制造奔驰");
return null;
}
}
//奥迪工厂
class AodiFactory implements CarFactory{
@Override
public Car createCar() {
System.out.println("制造宝马");
return null;
}
}
