Logback
Logback is a logging framework for Java applications, designed as a successor to the popular log4j library. It provides a flexible and efficient logging system with features such as configurable output formats, multiple appenders (e.g., console, file, database), and log level filtering. It is widely used in enterprise Java projects for debugging, monitoring, and auditing purposes.
Developers should learn Logback when building Java applications that require robust and configurable logging, such as web services, microservices, or large-scale systems where tracking application behavior is critical. It is particularly useful in production environments for diagnosing issues, performance monitoring, and compliance with logging standards, offering better performance and more features than its predecessor log4j.
