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.In CommonJS's specification, each JavaScript file is a separate module context, in which the attributes created by default are private. In other words, variables defined in one file (including functions and classes) are private and invisible to other files.Explanation of two sets of jre她笑道：黄家自然不缺这些的。新生历19世纪 战后的帝都盛行起人体与机械相融合的「机关拳斗」。因战争失去父亲、母亲仍未恢复意识的孤独少年列比乌斯，在收养他的伯父扎克的指导下，开始在机关拳斗的舞台崭露头角……人类的尊严与文明的未来相互碰撞，尖峰对决就此开幕。影片主要讲述了心存梦想的刘小二终于开始了自己憧憬过无数遍的大学生活，五个来自天南地北不同性格，习惯和家庭背景的女孩凑到了一起，开始了有欢笑和泪水，有梦想的大学时光。性格外向的班长吴静喜欢上了同班的坏小子肖张并展开了一系列的追求。但肖张却发现自己爱上了刘小二而拒绝了吴静的示爱，自尊心极强的吴静由此对昔日的好闺蜜，好室友刘小二万般排挤，带头孤立她。导致刘小二因为种种压力选择了退学....柳成得到消息，也瞬间明白过来，原来这些人也是为了营救子婴，看来是搞了个大大的乌龙。
