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.Advantages of Publish Subscription Mode:In order to breed offspring, the giant konjac can be called "by hook or by crook". It even has a dexterous system to fool insects and let them meet all their needs. Giant taro can quickly emit a smell of carrion to attract flies. Accidentally, flies enter a carefully designed secret room. The giant taro captures it with its huge flowers. The two rows of thick long hair and smooth outer wall make it impossible for insects to find an exit. At this time, the pistil also secretes a liquid that sticks to the flies. By the morning of the next day, it is time for the stamens to appear. It will make the flies covered with pollen. When it is finished, the long hairs on the flowers will shrink back and let the flies leave. Soon after, "unrepentant" flies will patronize another giant taro, and everything will happen again. At this time, when the "detained" fly licks the stigma of the pistil, the pollen it had previously stuck to the body will smoothly fall on the pistil of the flower, and the pollination task will be completed.
