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.Continue to more, I heard that the difficulty of purgatory is finally going to be updated, so I just said two words.他正色道：家父已经相准了人家，只等晚辈学业完结，回京就要成大礼。这是一个人民警察与黑恶势力进行殊死搏斗的惊险故事；这是中国第一部描写“管警察的警察”的电视剧；这也是灵与肉、情与法、爱与恨、正义与邪恶、奉献与贪婪激烈冲突的人生戏剧。故事的主人公是公安战线第一代督察警，老百姓亲切地称谓他们为“警中警”……故事发生在绿江市。丁潮受人指使绑架了绿江市建筑业巨头丽都集团总裁张大洋，市公安局副局长马云山指挥刑警队，成功解救了人质，受到政法委陈副书记的高度评价。丁潮在医院莫名其妙地死去，这让刑警支队副支队长常健非常恼火，他认为丁潮的案子和三年前杀害了三名警察的“蓝平大侠案”有关。两人忙见礼：见过世子。
