Java timer and java Timer I have been practicing in Beijing for more than a month, and I have been in touch with a lot of things. Today, the leaders hold a meeting, saying that the server is under too much pressure, the customers are not satisfied, and the access speed is demanding, some operations in our project do not need to be written dynamically to static ones.

Design a program to check the status every 20 ms. timers. during the timer test, it was found that the time for the previous timer function calls was the same (no problem occurred when the interval was changed to more than 1 s ), lock is also used (maybe I don't quite use lock ). Changed to system. Threading. Timer. The test found that: The
