Setting the Log Level of a Logger</h3>
The log level of a logger controls the severity of messages that it
will log. In particular, a log record whose severity is greater than
or equal to the logger's log level is logged.
<P> A log level can be <code>null</code>, in which case the level is inherited
from the logger's parent.
<P> Note: Logger handlers also have a log level. A log record
must first pass the logger's log level before it is compared to the
handler's log level.
<pre>
// Get a logger
Logger logger = Logger.getLogger(<font color="#0066ff"><i>"com.mycompany"</i></font>);
// Set the level to a particular level
logger.setLevel(Level.<font color="#0066ff"><i>INFO</i></font>);
// Set the level to that of its parent
logger.setLevel(null);
// Turn off all logging
logger.setLevel(Level.OFF);
// Turn on all logging
logger.setLevel(Level.ALL);
