Java Util Logging is a built-in logging framework in the Java programming language that allows developers to record log messages from their applications. It provides a simple way to track events, errors, and other important information during the execution of a program. This framework supports different logging levels, such as INFO, WARNING, and SEVERE, enabling developers to filter and manage log output effectively. The framework is part of the java.util.logging package and can be easily configured through properties files or programmatically. It supports various output formats and can direct logs to different destinations, such as the console or files, making it a versatile tool for monitoring application behavior and diagnosing issues.
