一. 抽象工厂方法接口

package designpattern.factory.factorymethod;


import designpattern.factory.simplefactory.noodles.INoodles;

/**
 * 工厂方法模式
 */
public interface INoodlesFactory {
     INoodles createNoodles();
}

二. 接口实现类

LzINoodlesFactory

package designpattern.factory.factorymethod;


import designpattern.factory.simplefactory.noodles.INoodles;
import designpattern.factory.simplefactory.noodles.LzNoodles;

public class LzINoodlesFactory implements INoodlesFactory {
    @Override
    public INoodles createNoodles() {
        return new LzNoodles();
    }
}

PaoINoodlesFactory

package designpattern.factory.factorymethod;


import designpattern.factory.simplefactory.noodles.INoodles;
import designpattern.factory.simplefactory.noodles.PaoNoodles;

public class PaoINoodlesFactory implements INoodlesFactory {
    @Override
    public INoodles createNoodles() {
        return new PaoNoodles();
    }
}

ReganINoodlesFactory

package designpattern.factory.factorymethod;


import designpattern.factory.simplefactory.noodles.INoodles;
import designpattern.factory.simplefactory.noodles.ReganNoodles;

public class ReganINoodlesFactory implements INoodlesFactory {
    @Override
    public INoodles createNoodles() {
        return new ReganNoodles();
    }
}

三. 测试类

package designpattern.factory.factorymethod;


import designpattern.factory.simplefactory.noodles.INoodles;

public class Test {
    public static void main(String[] args) {
        INoodlesFactory noodlesFactory = new LzINoodlesFactory();
        INoodles noodles = noodlesFactory.createNoodles();
        noodles.desc();
    }
}
