We have been using logging in Java and different code needs 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());
   }
}
