setResourceBundle() method of a Logger class used to set a resource bundle on this logger.we have to pass resource bundle object as a parameter to this method.After setting resource bundle all messages will be logged using the given resource bundle for its specific locale.
Syntax:
public void setResourceBundle(ResourceBundle bundle)
Parameters: This method accepts one parameter bundle which represents resource bundle that this logger shall use.
Return value: This method returns nothing.
Exception: This method throws following Exceptions:
- NullPointerException – if the given bundle is null.
- IllegalArgumentException – if the given bundle doesn’t have a base name, or if this logger already has a resource bundle set but the given bundle has a different base name.
- SecurityException – if a security manager exists, this logger is not anonymous, and the caller does not have LoggingPermission(“control”).
Below programs illustrate the setResourceBundle() method:
Program 1:
Java
// Java program to demonstrate// Logger.setResourceBundle() methodimport 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); // Log the ResourceBundle Name details logger.info("Resource Bundle " + logger.getResourceBundleName()); }} |
Output:
For the above program, there is a properties file name resourceBundle.properties. we have to add this file alongside the class to execute the program.
The output printed on console of Eclipse is shown below-
Program 2:
Java
import java.util.ResourceBundle;// Java program to demonstrate// Logger.setResourceBundle() methodimport java.util.logging.Logger;public class GFG { private static Logger logger = Logger.getLogger( GFG .class .getPackage() .getName()); public static void main(String args[]) { // Create ResourceBundle using getBundle // Resource is a properties file ResourceBundle resbundle = ResourceBundle.getBundle("resourceBundle"); // Set ResourceBundle to logger logger.setResourceBundle(resbundle); // Log the ResourceBundle Name details System.out.println("Resource Bundle Name - " + logger.getResourceBundleName() + " and Locale - " + logger .getResourceBundle() .getKeys()); }} |
Output:
For the above program, there is a properties file name myResource. we have to add this file alongside the class to execute the program.
output printed on console output is shown below-
