Programmatically set log4j to System.out

Question

I want to initialize a logger to simply write to the console.

E.g. (incorrect code)

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

Answer 1

You can add a ConsoleAppender to the logger at Runtime. The following link details this: http://howtodoinjava.com/2013/04/08/how-to-programmatically-configure-appenders-in-log4j/

Answer 2

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.

Java Util Logger
