Log4j an introduction

Log4J is a logging library that helps us create log statements that are way more powerful than System.out.println("...").

  • Log4J messages can be formatted with a timestamp, source, and many other things.
  • The Log4J system is initialzed using a property file, which determines the destination, and formatting of the log messages.
  • Log messages can be selectively turned on/off by modifying the property file.






 

Here is Log4J's documentation page. It has a very good introduction and a wiki
