Configure LOG4J in INTELLIJ in Windows.

IntelliJ debugger for temporary logging

In this video, it is shown how to use Log4j in Intellij. Sorry for the audio quality :) Log4j zip file link - https://logging.apache.org/log4j/1.2/... Properties file link - https://www.javatpoint.com/log4j-prop....

 import java.util.logging.*;

public class Logging {
    private static Logger logger = Logger.getLogger("Logging Class");
    public static void main(String[] args) {
        logger.info("Hello World");
        System.out.println("Hi");
    }
}

import java.util.logging.*;

    public static void main(String[] args) {
        try {
            logger.info("Hello World");
            System.out.println("Hi");
        } catch (RuntimeException ex) {
            logger.log(Level.SEVERE, "erro" + ex.getMessage(),ex);
        }
    }
}

    public static void main(String[] args) {
           try {
            logger.info("Line No: " + new Exception().getStackTrace()[0].getLineNumber());
            System.out.println("Hi");
            logger.info("Line No throw: " + new Throwable().getStackTrace()[0].getLineNumber());

        } catch (RuntimeException ex) {

    }
}

This video discusses Log4j and the log4j properties file. We discuss how to implement Log4j with a Maven-enabled Eclipse Dynamic Web Application with Tomcat. Note that I have the logging levels incorrect in the video. The proper order, from most severe to least severe, is: FATAL ERROR WARN INFO TRACE ALL Typically, the more severe, the less verbose. In other words, you'll usually see quite a few TRACE, and (hopefully) not many FATAL. Source code: https://github.com/discospiff/JavaFul...
