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.Good-looking, continue to be moreHulu无节操喜剧《高玩救未来 Future Man》第二季定于美国时间明年1月11日上线，在新一季中未来战士Wolf（Derek Wilson饰）及Tiger（Eliza Coupe饰）发现他们修正未来的计划出了偏差，在2162年的新未来世界中Stu Camillo（Haley Joel Osment饰）因制造了解药而掌权，他正准备把人类移居到火星去。一个名为Pointed Circle，想拉Stu下台的地下组织希望招募Josh（Josh Hutcherson饰），但主角实在分不清哪方才是好人。同时间Wolf迅速适应了新世界，相对Tiger则更想逃离此地，而这三货得想出拯救世界的新方案。[Investigation] Behind the Scenes of China's Crude Oil Spot Trading: Grey Crude Oil Futures Market Not ExitingFor example, the occurrence of accidental injuries.兄台又何必在意？以兄台这般人品，谁也不敢看轻了。
