    Default Logger custom level help

    Ok, i know that i am doing something wrong and if possible would like to be pointed in the right direction. Im just learning java, my background is in c/c++.

    I need to be able to add custom levels to the logger and im defiantly doing it wrong. Couldnt find much on the internet about it.

    Any help would be greatly appreciated. Here is my code so far.

    import java.util.Scanner;
    import java.util.logging.FileHandler;
    import java.util.logging.Level;
    import java.util.logging.Logger;
    import java.io.*;
    public class LogRunner {
    	public static void main(String[] args) {
                       // This is what i could come up with so far but its wrong.
    		   // Create the new levels
    	 final Level LogRunner debug = new LogRunner();
    	 final Level LogRunner error = new LogRunner();
    			FileHandler hand = new FileHandler("application.log");
    			  Logger log = Logger.getLogger("log_file");
    			  log.debug("This is bad debug it! ");
    			  log.info("Here is the info ");
    			  log.warning("DANGER DANGER ");
    			  log.error("There seems to be an error ");
    		catch(IOException e){}

    Thanks in advance for any help

    Default Re: Custom Log level help

    1) Create a new class definition that extends Level. You must implement one of the protected constructors, and call the super constructor within this constructor.
    2) Create an instance of this new class using the constructor defined in (1), be sure to set its level value as needed (see the API for Level for the values defined in the default Level classes).
    3) Set the level of the Logger using this custom level.
    Try the above, and if you get stuck post back with all relevant code.
