We have been using logging in Java and different code requires different levels of logging. Hence these Levels will come in handy.

Code sample:

import java.util.logging.Logger;import java.util.logging.Level;public class JavaLogger{   public static void main(String args[])   {      JavaLogger javaLogger = new JavaLogger();      javaLogger.proceed();   }      private void proceed()   {      //Creating the Logger      Logger logger = Logger.getLogger(JavaLogger.class.getName());      //Default Level is null. The Level needs to be explicitly set      logger.setLevel(Level.ALL); //Other options available in Java are SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST and OFF      System.out.println("Logger level: "+ logger.getLevel());   }}
