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.
In addition to news reports, Aban wrote a lot in his life. The first book is "Suffering China" published in 1930, and the last book is "Half Slave, Half Free: This Fragmented World" published in 1950, with 11 kinds. Among them, I have to mention the Biography of Hua Er published in 1947, which has long been translated by Mr. Yong Jiayuan and included in the Translation Series of the History of the Taiping Heavenly Kingdom published by Zhonghua Book Company in 1985. Because it is not widely circulated, few people may know it. Otherwise, the works written by the Foreign Gun Team and Walter in recent years should not be so irresponsible and astonishing. Aban dropped out of school halfway and has not received any historical training since then. He is usually busy with interviews and does not want to cure history. He is cautious and profound, which is far beyond the level of ordinary historical amateurs. After Walter died in Ningbo, only a handful of his works have been studied in the world. None of them were written by Chinese. Fortunately, with Aban's Biography of Walter, this period of history is full of flesh and blood. The writing process of this book has also gone through ups and downs. After the book was finished, the only manuscript had not yet been sent to the publishing house in New York, which was convenient for the Japanese gendarmes to break into the house and rob it in 1940. Ten months of efforts were destroyed. The evil deeds of the Japanese delayed the publication of the book for seven years, and also caused Abando to suffer from writing again. This passage is described in detail in this book, and the background is explained here.

Javascript neither supports abstract classes nor has the concept of interfaces. Therefore, be very careful when using the state mode. If you forget to implement the buttonWasPressed method for a state subclass when writing a state subclass, an exception will be thrown when the state switches. Because Context always delegates requests to the buttonWasPressed method of the state object. Therefore, let the abstract method of the abstract parent class throw an exception directly, which will be found at least during the program run.
