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.众人忙答应，一齐回去睡觉不提。陈奎虽然这么说，但内心里和所有人一样，同样在疑惑。故事背景为80年代的美国，底特律郊外一所私立高中里，有这么两种学生：怪胎和书呆。怪胎游手好闲、惹是生非，书呆懦弱无能，只会读书。Lindsay（琳达·卡德里尼 Linda Cardellini 饰）学习成绩拔尖，因为不想被划入“书呆”行列，她主动结识了几个“怪胎”，成为他们的朋友。她的弟弟Sam（约翰·弗朗西斯·达利 John Francis Daley 饰）是个不折不扣的书呆，不仅本人软弱无能，还交了一群同样怯懦的书呆朋友。
