Logger getResourceBundle() Method in Java with Examples

Last Updated : 03 Jun, 2021

getResourceBundle() method of a Logger class is used to localise resource bundle for this logger. We can set ResourceBundle either by the setResourceBundle method or mapped from the resource bundle name set via the getLogger factory method for the current default locale and this method will return a ResourceBundle set by above-mentioned ways. If the result is null, then the Logger will use a resource bundle or resource bundle name inherited from its parent.
Syntax:

public ResourceBundle getResourceBundle()

Parameters: This method accepts nothing.
Return value: This method return localization bundle.
Below programs illustrate the getResourceBundle() method:
Program 1:

Java

// Java program to demonstrate
// Logger.getParent() method

import java.util.logging.*;
import java.util.ResourceBundle;

public class GFG {

    private static Logger logger
        = Logger.getLogger(
            String
                .class
                .getPackage()
                .getName());

    public static void main(String args[])
    {

        logger.info("printing the message...");

        ResourceBundle rs
            = logger.getResourceBundle();

        logger.info("Resource Bundle " + rs);
    }
}

Output:

Program 2:

Java

// Java program to demonstrate
// Logger.getParent() method

import java.util.logging.*;
import java.util.ResourceBundle;

public class GFG {

    private static Logger logger
        = Logger.getLogger(
            GFG
                .class
                .getPackage()
                .getName());

    public static void main(String args[])
    {

        // Create ResourceBundle using getBundle
        // myResource is a properties file
        ResourceBundle bundle
            = ResourceBundle
                  .getBundle("myResource");

        // Set ResourceBundle to logger
        logger.setResourceBundle(bundle);

        // Get ResourceBundle from logger
        ResourceBundle rs
            = logger.getResourceBundle();

        // Log the ResourceBundle details
        logger.info("Resource Bundle "
                    + rs.getBaseBundleName());
    }
}

For above program there is a properties file name myResource. we have to add this file along side the class to execute the program.
