Or you can use log4j via SLF4J:

void *debug*(String
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
format,
   Object
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html arg1,
   Object
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html arg2)

Log a message at the DEBUG level according to the specified format and
arguments.

This form avoids superfluous object creation when the logger is disabled for
the DEBUG level.

*Parameters:*format - the format stringarg1 - the first argumentarg2 - the
second argument
http://www.slf4j.org/api/org/slf4j/Logger.html#debug(java.lang.String,%20java.lang.Object,%20java.lang.Object)

   Hi Tim,
  
   The Logger class has a way of checking the level first.
  
   First put this in your instance variables:
  
  private static final Logger logger =
   Logger.getLogger(my.package.MyClass);
  
  private final boolean debug = logger.isDebugEnabled();
  
   Then put this in your method:

  }

 Hi,
  
   I am writing a Log Utility to check the log level first before
   creating a
   string object. For example, if my log level is INFO, and I call:
  
   log.debug(new String(test));
  
   It will still instantiate the String object even thought it doesn't
   log
   anything.
  
   So I would like to write an Utility to check the level first, if the
   log
   level is lower, then I don't have to instantiate the object and just
   skip
   it.
   Anybody knows what is the easy way to do that?

The Logger.isDebugEnabled() method applies to all of the classes that use your

Also note that

log.debug(new String(test))

is the same as

log.debug(test);

and in general:

new String(test)

is the same as

test
