, static is limited to hiding, and for variables, static has the following two functions.2) The second function of static is to keep the contents of the variable persistent. Variables stored in the static data area are initialized at the start of the program and are the only one initialized. A total of two variables are stored in static storage: Global variables

parallel test that could cause another test to fail.But roughly speaking, this example can be said to be a mistake, how to configure UserService is not the responsibility of usercontroller, so the correct way is to remove the UserService configuration related code, let it manage it yourself:A fourth exampleIn this example, the Loggingservice log method requires

version of the method's interpretation with the compiled version with the method's dispatch table.Hotspot virtual machines have many JIT-compiled optimizations, but one of the most important optimization techniques is inline. During inline, the JIT compiler effectively extracts the method body of a method into its callers, thereby reducing the virtual method invocation. For example, take a look at the following code:public int add(int x, int y) { ret

the Ctriangle, Csquare, and Ccircle classes from the Cfigure class, representing triangles, squares, and circles, respectively.We are going to instantiate the types of these objects, so in these derived classes, the Figuretype method, the circumference method, and the area method are implemented. Although the method names in these 3 classes are the same, they are implemented differently, similar to overrides but with a different meaning.How to unders

Requirement: A string is stored in the database, the string is displayed as a QR code, and the information of the string is displayed after scanning the QR Code.Implementation Principle: Obtain the data from the database first, then generate the picture according to qrcode, then display the Picture.Key

I didn't plan to put this source code on. After all, it has been a long time and has never been improved. However, I found that many netizens asked me for this CodeI am a lazy guy. I don't want to send emails one by one, so I just moved to my blog. If you like it, I can do it myself! This message is based entirely on your own learning and practice of technology. It is
