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.爹娘爷奶更没人叫他们的名字，他当然陌生了。电影《银狐传说》讲述了当人类和狐仙的感情，遭遇了维护正义的捉妖师的阻隔下的纠葛。影片结合时下热点，以人狐恋为主线，一方面展现人性的本质，一方面向人们传达世间的真情流动。可杨长帆没动肝火，他理解杨寿全为什么不理解自己，他毕竟是个古人，眼界到这里已经难得了。《High School: Love On》是一部青春幻想浪漫成长电视剧，讲述变身人类的天使与热血高中学生们爱情、友情的故事。随着洛菲菲的到来，原本平衡且平淡的表象被彻底打破，宿命使然洛菲菲成了史上最惨穿越女主，更莫名其妙的成了弱鸡反派大boss。
