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.此剧讲述了宅男公务员暗行御史和野心勃勃,爱管闲事,欲望的化身奇别夫人调查贪官污吏案件,进而探寻巨大阴谋真相的愉快搜查故事。玉泽演剧中将饰演状元及第最年轻的弘文馆副修撰暗行御史Lion一角。他拥有秀丽的外貌,温柔的眼神,是具备一切的英姿飒爽的人物。金惠允剧中将饰演打破传统的新女性金曹亦一角。她是认为活着也可以离婚的现实主义者,是个潇洒地结束离婚诉讼,灿烂地开启人生第二幕的人物。? ? ? ? ?
