D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:

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.
