设计模式 之 工厂方法模式

简介

简单工厂模式还是得修改factory类来构建出新的对象.

工厂方法模式将factory也抽象成一个抽象接口

code

public interface Car {
    void name();
}

public interface CarFactory {
    Car getCar();
}

public class Consumer {
    public static void main(String[] args) {
        Car c1 = new WuLingFactory().getCar();
        Car c2 = new TeslaFactory().getCar();

        c1.name();
        c2.name();
    }
}

public class Tesla implements Car {
    @Override
    public void name() {
        System.out.println("特斯拉");
    }
}

public class TeslaFactory implements CarFactory{
    @Override
    public Car getCar(){
        return new Tesla();
    }
}

public class WuLing implements Car {
    @Override
    public void name() {
        System.out.println("五菱宏光");
    }
}

public class WuLingFactory implements CarFactory{
    @Override
    public Car getCar(){
        return new WuLing();
    }
}
