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.The newspaper said: "The total number of cancer deaths in the United States showed a downward trend for the first time in 2005." "Cancer is a chronic disease that can be treated, controlled and even cured." In the past, it was believed that cancer would lead to death, and it would take less than three months.

The decline in the death rate of cancer patients in turn proves that this change of understanding is close to the right direction. Western medicine came from the West. At present, the number of cancer survivors in the United States is 1/29 of the total population, while that in Shanghai is only 1%, which is far from other places. This shows that Shanghai's understanding and treatment of cancer are still shrouded by the shadow of past mistakes.
