How to answer such questions? Consistent Zhihu style, the following various statements have, but the top one is actor Zhang Yi's answer (of course, there are reasons why he is a celebrity), but his answer is as follows:
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.

James Norton and Robson Green return as the unlikely 1950s crime fighting duo, Vicar Sidney Chambers and Police Inspector Geordie Keating, in the third series of Grantchester, produced by Kudos. The six-part series is based on The Grantchester Mysteries by James Runcie. Tessa Peake-Jones is back as Sidney’s sharp tongued housekeeper Mrs Maguire who keeps the vicar in check; Morven Christie reprises her role as Sidney’s forbidden lover Amanda; Al Weaver returns as the timid curate Leonard Finch; Kacey Ainsworth is back as Geordie’s long suffering wife Cathy, Lorne MacFadyen puts his police helmet back on to play DC Phil Wilkinson and Seline Hizli returns as the feisty police secretary Margaret. And of course it wouldn’t be Grantchester without the return of the gorgeous black Labrador Dickens.
