After seeing so many students in last four years, I have decided to write this article about the new loggers which are widely being used by the industry. Almost all the university students I have seen are familiar with Log4j 1.x (at least heard about it) but most of them even did not hear about SLF4J and Logback. The purpose of this article is introducing SLF4J and Logback and convincing you towards them. Before getting into the topic, be informed that Log4j 1.x is not being maintained after August 5, 2015 and Ceki Gülcü the developer of Log4j came up with the new tools SLF4J and Logback. Technically, Logback is an enhanced successor of Log4j and performs better than Log4j.
He did a good job, but we have to move forward.
