ColorDodgeIn 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.筱原凉子继续饰演独来独往的最强派遣职员大前春子，从平成来到令和时代，工作方法也需要发生改变。都已经以社会人的身份生活，成为了正经的大人。我先来跟王爷求亲，等会再和我爹我娘去求老王爷和老王妃。海天集团董事长石磊是精明能干的商人，同时也是极富爱心的社会公益人士。在一次度假途中，他邂逅了女董事长沈心瑷，两人一见如故。沈心瑷的未婚夫在结婚前夕死于车祸，沈心瑷想要完成他修建福利院的夙愿。由于商业操作的失误，骏豪集团陷入了空前的财务危机，此时石磊向沈心瑷伸出援助之手，两人在的不断接触中，产生了爱情。然而，就在沈心瑷感觉幸福正靠近自己的时候，却意外发现了石磊还怀有更大的商业目的，她崩溃了，选择了离开。石磊没有想到，他已经离不开沈心瑷。一年后，在他们初次相遇的雪地里，石磊静静地坐在那里，沈心瑷来了，看着憔悴的石磊和美丽的、温馨的福利院，沈心瑷相信了石磊为自己所做的一切。衬着孩子们的笑脸，沈心瑷披上了婚纱。Club Friday The Series 10 不忠的爱之秘密
