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.PK No One Can Beat Asura汉普湾的观光旺季即将来临，风帆大赛也将展开，不过却发生了鲨鱼事件。方富商及主办人山姆路易斯执意不延后比赛及关闭海滩，以为能用鲨鱼网阻止任何鲨鱼进入，不料这条食人巨鲨是经过海军训的杀人机器，不但闯进赛，肆恣猎杀选手们，之后更杀死所有追捕它的人。海洋学家比利和索伦家人要如何对付这可怕的怪物呢？Regarding the author of this book, Haret Aban, Japan's Matsumoto Chongji made the following description in "Shanghai Times" (Shanghai Bookstore Publishing House, 2005):苞谷见大大小小的黄球挤作一堆，十分欢喜，用勺子舀了那颗最大的，正要往嘴里送，就听香荽道：苞谷，三姐姐也想吃那个。在这部纪录片中，亚历克斯信任他的双胞胎马库斯（Marcus）在失去记忆后告诉他过去的事。但是马库斯隐藏了一个黑暗的家庭秘密。
