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.　　灭门惨剧时，杨月产下一男婴，郑武要斩草除根，杨月恳求乔征将婴孩带出帅府，交给他人抚养。郑武为此使出毒计，如果没人交出郑家遗孤，就将所有的婴孩全部杀掉。原子物理学家冲田博士发现了珍贵的超放射性元素[超铀],G博士希望凭借这种元素,帮助他实现征服世界的大计.为了维护世界和平,风见志郎变身为假面骑士V3,决意与G博士率领的毒蝎帮周旋到底……2.
