Logging is the process of writing log messages during the execution of a 

program to a central place.This logging allows you to report and persist

error and warning messages as well as info messages (e.g., runtime 

statistics) so that the messages can later be retrieved and analyzed.

private static final Logger LOGGER = Logger.getLogger( ClassName.class.getName() );

​

Logger logger = Logger.getLogger("newLoggerName");
