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.克劳德夫人是一家致力于卖淫的生意兴隆的公司的负责人，这使她在法国的政治和犯罪领域都拥有权力。但帝国的末日比她想象的要近。生母与养母之间争夺孩子抚养权的故事，一幕幕感人肺腑Showtime正式预订萨莎·拜伦·科恩打造的讽刺剧集《谁是美国？》，该剧共7集，本周日首播。Showtime将该剧形容为“可能是电视史上最具危险性的一档电视节目”。The meta-sharing mode uses sharing technology to effectively support fine-grained objects and make them share.
