抽象工厂模式

新增抽象工厂接口 CourseFactory（课程工厂）

public interface CourseFactory {
    //获取视频
    Video getVideo();
    //获取手记
    Article getArticle();
}

新增手记的抽象类 和 抽象方法

public abstract class Article {
    public abstract void produce();
}

新增视频的抽象类 和 抽象方法

public abstract class Video {

        public abstract void produce();

}

继承手记抽象类

public class JavaArticle extends Article {

        @Override
        public void produce() {
                System.out.println("编写java手记");
        }

}

继承视频抽象类

public class JavaVideo extends Video {

        @Override
        public void produce() {
                System.out.println("录制java视频");
        }
}

新增具体实现课程抽象工厂接口的类javaCourseFactory

public class javaCourseFactory implements CourseFactory {

        public Video getVideo() {
                return new JavaVideo();
        }

        public Article getArticle() {
                return new JavaArticle();

        }
}

开始测试

public class Test {

        public static void main(String[] args) {
                CourseFactory courseFactory = new javaCourseFactory();
                Article article = courseFactory.getArticle();
                Video video = courseFactory.getVideo();
                video.produce();
                article.produce();

        }
        
}
