Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.我一定会跟你把这两年耗完……混蛋。　　民国初年，北方某城市有一名为“苗家班”的戏班，班主苗人杰，女儿金钗，两个养女翠玉、秀凤。苗家班以唱戏为生，没想到却卷入到一场正义与邪恶的斗争之中。　　据导演何群透露，《新青年》将区别于传统主旋律史诗剧的严肃刻板，适当加入轻喜剧的叙事成分，呈现一种幽默的风格。何群曾表示，该剧涉及辛亥革命、二次革命、新文化运动、第一次世界大战、五四运动、中国共产党成立、南昌起义等历史事件，但采取的不是正面强攻的方式，而是聚焦大历史背景中的小人物命运。杨长帆这才赶忙掏银子，完璧归赵。《校花的贴身高手3》无缝衔接第二季，气势涛涛，火热来袭，将围绕世家秘笈层层铺开精彩剧情。为了世家秘笈的强大力量，安建文将上古世家子弟囿于恐怖密室，支离破碎的人体模特，险象环生的暗道机关，这一次，林逸能否成功解开密室之谜，瓦解他的阴谋诡计救出瑶瑶呢？不论你想要激升的肾上腺素，还是英雄征战的正义感，《校花3》全新震撼剧情，将带领你继续探索充满异能的青春世界！[Implementation Time]: 20040301
