简介

如果我们简单工厂中的每个工厂扩展其功能，使其能够生产多种产品，那么工厂方法就演变成了抽象工厂模式。

示例

产品抽象

interface Car {}
class Jeep implements Car {}
class Porsche implements Car {}

工厂抽象

interface Producer {
	Car produceJeep();
	Car producePorsche();
}
class JihuiProducer implements Producer {
	@Override public Car produceJeep() { return new Jeep("jihui jeep"); }
	@Override public Car producePorsche() { return new Porsche("jihui porsche"); }
}
class LailiProducer implements Producer {
	@Override public Car produceJeep() { return new Jeep("Laili jeep"); }
    @Override public Car producePorsche() { return new Porsche("Laili porsche"); }
}

Client

public class Main {
	public static void main(String[] args) {
        Producer producer1 = new JeepProducer();
        Car jeep = producer1.produce();
        Producer producer2 = new PorscheProducer();
        Car porsche = producer2.produce();
    }
}
