java.util.logging

  • This page provides a comprehensive overview of the Java Logging API, including both its interfaces and classes.

  • Key interfaces include Filter for controlling which log records pass through and LoggingMXBean for managing the logging system.

  • The API offers a variety of classes that are useful for controlling how and where log messages are published.

  • These classes include core components like Logger, Handler, and Formatter as well as more specialized ones such as different Handlers and the global LogManager.
