The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.杨长帆收铳冷笑，别高看自己，我对你的命没那么大兴趣。Unicom小娃儿动了兴致，觉得这样很好玩，他自己又不想动，便有样学样，对小七道：小七，帮我把花生端来。Coco五人来至人迹罕至的湖边，五人下水嬉玩，面对着Coco曼妙身材，Adam禁不住在水中对Coco毛手毛脚，又窥看对方沐浴更衣，被Coco发现后，Adam竟欲对之强来，身穿比坚尼泳装的Coco慌不择路的逃命，却在茂密丛林中迷路，Coco只好致电向志彦求助，但信号却是时断时续模糊不清，最后更信号中断，叫志彦担忧不已…板栗大惊道：泥鳅，不是让你去水路拦截我小舅和万元了么，咋跟小葱碰上了？瞅见妹妹身上衣裳已经换了，你改装？小葱得意地说道：我把衣裳脱给小草穿上，让她扮作我的模样守在山前，我就去拦截泥鳅了。
