Java Logging Examples : How To Compare Log Level Severity

Intro

This examples will demonstrates how to compare log level severity for each log level. The java.util.logging.Level class has an intValue() method that return the integer value of Level‘s severity.

Examples

package com.freesamplecode.java.logging;

import java.util.logging.Level;

public class CompareLogLevelSeverityDemo {
 public static void main(String[] args){
  Level info = Level.INFO;
        Level warning = Level.WARNING;
        Level config = Level.CONFIG;
        Level finest = Level.FINEST;
        
        if (info.intValue() < warning.intValue()) {
            System.out.println(info + "(" + info.intValue() + ") is less severe than " +
                    warning + "(" + warning.intValue() + ")");
        }

        if (finest.intValue() < info.intValue()) {
            System.out.println(finest + "(" + finest.intValue() + ") is less severe than " +
                    info + "(" + info.intValue()+ ")");
        }
        
        if (config.intValue() < warning.intValue()) {
            System.out.println(config + "(" + config.intValue() + ") is less severe than " +
                    warning + "(" + warning.intValue()+ ")");
        }
 }
}

Output

INFO(800) is less severe than WARNING(900)
FINEST(300) is less severe than INFO(800)
CONFIG(700) is less severe than WARNING(900)
