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.小葱听了皇后的话。既然备此目的明确的礼品，苏莱曼对杨长帆的敌意也打消了一些，请一行人进宫。顿了一下又指着儿媳妇刘氏道，黄豆他娘也是刘家塘最出名的闺女，叫青木给娶来了。Ordinary automatic physical attack (and automatic shooting) is right-click point monster, skills can be numeric keys, key combinations or something as long as there are keys on the keyboard can be set as shortcut keys.Beijing
