information; the output destination of the log information specifies whether the log will be printed to the console or file, and the output format controls the display of the log information. 2.1.

Five common rules in Java Logging Logging is a key factor that needs to be considered during software development. When a product encounters an error, log files are usually the primary choice for error analysis. Moreover, in many cases, they are the only information we have in hand that can be used to identify the situation and root cause of the problem. Therefore, it is extremely important to correctly record the required information. The followin

Java Logging Java has a log system (logging framework) that records the runtime information of a program on the JVM ). The program can use logger (Java. util. Logging. Logger) to record logs. Java uses a hierarchical naming method
