Design patterns are reusable solutions to common software design problems, providing a structured approach to building robust, maintainable, and scalable systems. They capture best practices and proven techniques, allowing developers to solve recurring issues efficiently without reinventing the wheel. Originating from the work of Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (the “Gang …
In the java.util.logging package, Handlers are components that take LogRecord objects from a Logger and publish them to a specific destination (console, file, socket, etc.). Commonly Used Handlers Commonly Used Methods Simple Program: Using ConsoleHandler Output: A Handler decides where the logs go: console, file, remote socket, etc.You can attach multiple Handlers to a single …

SLF4J (Simple Logging Facade for Java) is a Java API designed to serve as a simple facade or abstraction for various logging frameworks such as: Log4j Logback java.util.logging (JUL) Apache Commons Logging It allows developers to plug in the desired logging framework at deployment time without modifying the source code. Why Use SLF4J? Decoupling: Your …
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. Evolution: Log4j 1.x: Original version, now deprecated. …

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 …
