When I think about this matter again, I feel that he is lucky in the real misfortune. He is more deadly than Jiang Yong in the position where he was splashed.

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.5 Dark Spirits岸田今日子冈本夏夫然后张槐洗了一把，换了身衣裳，清清爽爽地上桌吃饭，跟众人叙别后诸样事。3.2 Turn on and off the event scheduler真爱也许在我们心中不再永恒，但是我们相信这样的爱情存在于天堂……都市精英、人称“娜公子”的张晓娜，刚过三十就荣升为副总裁。职场得意，可情场一片荒芜，连一场真正的爱情都没有过。以晓娜人生大事为己任的弟弟小维，在著名婚介所给她办理至尊VIP，一场遴选姐夫的故事拉开序幕。这一对姐弟俩，一个是事业成功却拥有少女情怀的三十岁未婚女、一个是二十二岁电脑奇才，这对奇葩姐弟，由此展开了爆笑的婚恋之旅。上天不负有心人，晓娜终于迎来了爱情的拐点，因为一次相亲网站的相亲舞会，晓娜意外结识海外留学归来的常青，两人奇妙的缘分由此展开，小维也找到了属于自己的幸福。
