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.有此神将，何愁倭寇？余下两个倭寇已然有了应对。恶魔的浪漫前传，KK夫夫将如何走向结局？多年前，曾是楚国王宫中出色的禁卫大人，应该就是这一带了。玉米嗯了一声，径直往王府东面跑去。叶枫并不是一名弱质女子，她走私军火，贩卖人口，国际刑警屡次逮捕，都让她神通广大的逃脱，叶枫将于十日之内在中缅边界旳加莱镇接收一批有史以来最庞大的生鸦片大买卖。
