5. 工厂方法模式

1.抽象产品类

public abstract class AbstractProduct {
	
}

2.抽象工厂类

public abstract class AbstractFactory {
	public abstract AbstractProduct createProduct();
}

3.具体产品类

public class Product extends AbstractProduct {

}

4.具体工厂类

public class Factory extends AbstractFactory {

	@Override
	public AbstractProduct createProduct() {
		// TODO Auto-generated method stub
		return new Product();
	}

}

5.客户程序

public class Client {
　　　　//工厂方法,与抽象工厂的最主要区别可能就在此,单个对象的维度
	public AbstractProduct getProduct(AbstractFactory factory){
		return factory.createProduct();
	}
}

6.应用

public class App {
	public static void main(String[] args) {
		Client client=new Client();
		AbstractProduct product = client.getProduct(new Factory());
		
	}
}
