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.《破茧边缘》以对命运的控诉、对爱情的挣扎执着为主线，加强了令人感动的冲击。一对没有明天的爱侣，两段萦绕心间的恋痕，一场正邪与情义难择的内心交战。 　　片中故事讲述李苏及李苏弟从小父母双亡，姐李苏在外工作供应其弟成长、求学，姐弟两相依为命，情感深厚。李苏在少年时即与阔少留心田相恋，但因留家反对，两人于是相约私奔，可惜心田失约，李苏以为他移情别恋，而跳海自尽，幸得富商古瑞祥相救，并自此照顾李苏姐弟多年，他对李苏更暗中产生一份倾慕之情，而发展出一段微妙的忘年之恋。SNMP magnification attackYou can see that PizzaStore depends on a SImpleFactory, which depends on an abstract pizza.
