Log4j (short for Logging for Java) is a reliable, fast, and flexible logging framework developed by the Apache Software Foundation. It allows developers to log messages according to different severity levels and send those messages to multiple destinations like the console, files, GUI components, databases, or remote servers.

Hierarchical Logging in Java refers to the parent-child relationship among loggers based on their names. This structure allows you to configure logging behavior at higher levels (e.g., a package or module) and automatically apply or override it in child loggers. Loggers in java.util.logging are organized in a tree hierarchy, with the dot (.) separator defining …

Custom loggers allow you to define named loggers tailored to specific application modules, services, or classes. This modular approach helps in maintaining granular control over logging configuration, enabling separate log levels, handlers, and formatters for different components. Simple Program This shows how a custom-named logger (MyCustomLogger) is configured independently of the root logger. Problem Statement …
Java allows logging configuration directly in code. This gives developers full control over loggers, handlers, formatters, and levels at runtime, useful for dynamically adjusting logs or when file-based config isn’t practical. Simple Program Problem Statement LotusJavaPrince wants to build a logger that logs all suspicious activity to a file for compliance purposes. Mahesh, the security …
