E.g. (incorrect code)
Logger logger = Logger.getLogger(System.out);
logger.debug("test") //prints to System.out

If you are using Apachi Logger or Java util logger then you should need to know this that getLogger() method is not taking any class object as argument.
Apachi Logger for print on console - See Console Appender.
