How do I get the current Level of a Logger?

By Wayan in Logging 0 Comment

Here we demonstrate how to obtain the current level of the Logger instance. The log level will be inherited from the parent logger when the level is not set explicitly .

package org.kodejava.util.logging;

import java.util.logging.Logger;
import java.util.logging.Level;

public class LoggerGetLevel {
    private static Logger logger = Logger.getLogger(LoggerGetLevel.class.getName());

    public static void main(String[] args) {
        LoggerGetLevel demo = new LoggerGetLevel();
        System.out.println("demo.getLevel(logger) = " + demo.getLevel(logger));

        logger.setLevel(Level.WARNING);
        System.out.println("demo.getLevel(logger) = " + demo.getLevel(logger));
    }

    public Level getLevel(Logger logger) {
        Level level = logger.getLevel();
        if (level == null && logger.getParent() != null) {
            level = logger.getParent().getLevel();
        }
        return level;
    }
}
