滨海市公安局立即成立了专案组，张雷被任命为专案组副组长，与老资格的刑警陆延平搭档。对于张雷来说，侦破这起案件具有双重意义，既是他作为一名刑警必须要完成的职责，又是在为牺牲的好战友和失去了未婚夫的妹妹复仇。但是侦破工作进展得并不顺利，以狡猾擅于躲藏着称的雷老虎在案件发生后就迅速藏匿···In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.剧场版《刀剑神域剧场版：进击篇》的第二部《#刀剑神域剧场版 进击篇第二部 阴沉薄暮的诙谐曲#(劇場版 ソードアート・オンライン -プログレッシブ- 冥き夕闇のスケルツォ )》将于2022年秋上映~杰克（安迪·萨姆伯格 Andy Samberg 饰）是一位精明强干的警探，被他所捕获的罪犯能排上好长一列，然而，在其他同事，包括他那新上任的上司雷（安德鲁·布劳尔 Andre Braugher 饰）眼中，一心追求“成绩”的他似乎有那么一些“不守规矩”。艾米（Melissa Gallo 饰）出生于警察世家，作为家中唯一一个穿上警服的女孩，她明白自己肩上背负着怎样的重担，有些时候，这重担压得她都有些喘不过气了。坎卡伊和乔安之间的感情遭到了乔安家人的强烈反对，为了拆散两人，乔安的母亲斩断了乔安的经济来源，乔安逼迫坎卡伊卖身赚钱，两人之前的关系每况愈下。最终，忍无可忍的坎卡伊决定离开乔安，但等待着她的，并非一帆风顺的命运。其余秦旷等礼部的人一边要看热闹，一边还要让其他国家的使臣，使现场不至冷落，可忙了。
