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.卡门是一名奴隶也是女巫。她今年 19 岁，即将被绑在火刑柱上处死，因为她犯下了不可饶恕的罪行：爱上一名白人。不过，一名年长的男巫为她提供了得救的办法 — 穿越时空，去往没人相信女巫存在的地方。如果卡门答应放弃使用法力，就能获得穿越能力。卡门同意并发现自己置身于当今的哥伦比亚，开始了新的生活，认识朋友，甚至去上了大学。但是，一日为女巫，终身为女巫。听到韩信这样说，蒯彻总算是松了一口气。他们跑到林子更深处，板栗找了个隐蔽的地方，对秦淼道：你去，我帮你守着。
