For example, in Java, the Selector's select () method is used to implement this synchronous blocking operation waiting for an event to occur. In the implementation of select () under Linux operating system, a) will call epollCtl (epfd, opcode, fd, events) to register the events that have been registered in Initiation Dispatcher into Linux system, where fd means Handle and events means Handle events that we are interested in; B) Synchronize the occurrence of a blocked wait registered event by calling the epollWait method. Events on different event sources may occur at the same time. Once an event is triggered, the epollWait method will return. C) Finally, find the associated SelectorKeyImpl object by the event that occurred, set the event that occurred to the ready state, and then put the SelectorKeyImpl into the selectedSet. In this way, we can get the event-ready SelectorKeyImpl collection through the Selector.selectedKeys () method.

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.
