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.温蓝新一怒，亿万天兵天将降临花果山。As seen above on the LINUX system, many connections are in the SYN_RECV state (SYN_RECEIVED state on the WINDOWS system) and the source IP address is random, indicating that this is a SYN attack with IP spoofing.特种兵退役的穆鹰回归都市生活，误打误撞结识了马来西亚富商之女程燕羽，也因此被卷入了一场商业斗争的漩涡，在一番激烈的碰撞后，穆鹰惊讶的发现对方幕后黑手竟是自己当年执行最后一次任务要抓捕的毒枭老大叶灵均。罗七道：先生，只要料理了这些人，先前的小子跑不了。该片主要讲述了，六个线索人物错综交织，为毒品和百万美金相互争斗的故事。无厘头女作家“鲍菊”屡次试爱，每每受挫。奇葩黑帮三人组交易受阻，又丢失百万钱财。俊男毒枭初来中国，就被重伤放倒。毛贼侦探替人消灾，不料摊上三条人命。时尚老鸨伶牙俐齿，双刀火拼黑帮，好色副导色字当头，失手杀妻，智斗侦探。本风马留不相干的一群人，被卷入了一系列的复杂的事件中。2.
