Level getResourceBundleName() method in Java with Examples

The getResourceBundleName() method of java.util.logging.Level is used to get the localization resource bundle name of this level object. If localization bundle is present then this method returns name of bundle else method return null.

Syntax:

public String getResourceBundleName()

Parameters: This method accepts nothing.

Return: This method returns localization resource bundle name.

Below programs illustrate getResourceBundleName() method:
Program 1:

// Java program to illustrate
// getResourceBundleName() method

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

public class GFG {

    public static void main(String[] args)
    {

        // Create a Logger
        Logger logger
            = Logger.getLogger(
                        Object.class.getName())
                  .getParent();

        // Get level of logger
        Level level
            = logger.getLevel();

        // get localization resource bundle name
        String name = level.getResourceBundleName();

        // print level localization resource bundle name
        System.out.println("Localization resource"
                           + " bundle name = "
                           + name);
    }
}

Output:

Localization resource bundle name = sun.util.logging.resources.logging

Program 2:

// Java program to illustrate
// getResourceBundleName() method

import java.util.logging.Level;

public class GFG {

    public static void main(String[] args)
    {

        // Get level of logger
        Level level
            = Level.parse("SEVERE");

        // get localization resource bundle name
        String name = level.getResourceBundleName();

        // print level localization resource bundle name
        System.out.println("Localization resource"
                           + " bundle name = "
                           + name);
    }
}

Output:

Localization resource bundle name = sun.util.logging.resources.logging
