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.Fitz of Industrial Fire年过中旬的杰克是位银行网络安全高级主管，他凭其精于计算机防盗设计的经验备受高层重视。银行盗匪比尔绑架了杰克家人，并胁迫杰克为他们盗取银行一亿美元现金。为了家人杰克以身犯险，和罪犯展开了斗智斗勇的对决。天楚国本该姓楚，一场宫闱巨变致使帝后遇难，国家陷入风雨飘摇，国师风如歌当机立断独掌朝纲，十五年来，日渐成年的太子有心夺回失去的一切，奈何天楚已是风党天下……
