Learn a new technique or language, we must first learn how to adapt to this new technology, which in the adaptation process, we have to learn how to debug the program and play the corresponding log information, is called "as long as the log is good, no bugs can not solve", in our well-known information technology, The Log4xxx series, as well as the Android.util.Log packages for Android apps, are all for developers to get a better log information service. In the language of Python, we can also pl

First, what is SLF4Jwhen we do Java development, if we need to log logs, there are many log APIs to choose from, such as: Java.util.logging Apache log4j Logback What is slf4j again? Why is it better to use slf4j than to use log4j or java.util.logging? This is because SLF4J does not really implement logging compared to all of the mentioned logging libraries, but instead it is just a lay

No software is completely error-free, and application users may encounter unexpected results during the running of the program. To analyze and identify the causes of these problems, one of the methods that programmers use extensively is logging. In this article, you will learn how to use a circular buffer to efficiently log records through memory operations, rather than file operations. Choose the appropriate size for the buffer to ensure the dump-rel
