1. Use the singleton whenever possible The use of Singleton can reduce the load burden, shorten the loading time, and improve the loading efficiency, but not all of them are applicable to singleton. Simply put, singleton is mainly applicable to the following three aspects: First, controlling the use of resources and controlling concurrent access to resources through thread synchronization; second, controlling the generation of instances to save resour
Recently, the machine memory is full again. In addition to the new machine memory, we should also review our code. Many code compilation methods are too casual, these bad habits or lack of understanding of the programming language should be well suppressed.The following is a summary of some of the network resources that should be done as much as possible in Java programming. 1.

When the Synchronize method is called, it locks the current object directly, and other threads cannot invoke the other methods of the current object until the method finishes executing. So the method of synchronize is as small as possible, and should try to use method synchronization instead of code block synchronization.8. Use StringBuilder and StringBuffer for string connec
