Java in a Nutshell, 5th Edition

Level

Synopsis

This class defines constants that represent the seven standard severity levels for log messages plus constants that turn logging off and enable logging at any level. When logging is enabled at one severity level, it is also enabled at all higher levels. The seven level constants, in order from most severe to least severe are: SEVERE, WARNING, INFO, CONFIG, FINE, FINER, and FINEST. The constant ALL enable logging of any message, regardless of its level. The constant OFF disables logging entirely. Note that these constants are all Level objects, rather than integers. This provides type safety.

Application code should rarely, if ever, need to use any of the methods of this class: instead they can simply use the constants it defines.
