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.他身材魁梧，样貌端正，在一群粗汉中，显得有些突出。花无缺简直帅呆了。"超兽战队"为八手三郎版战队十周年纪念作.主角是科学亚加嫡米亚的学院的学生,忍耐不住神秘集团"伏特"的多次袭击,而集合有志之士穿上改良自太空服组成"超兽战队".故事发生在以色列，一名年轻的法国妇女Natalie被指控在婚礼当天晚上杀害自己的丈夫， 法国政/府派外交官Karim到现场帮助她并调查事情真相。Rolling shutter
