Java
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[])
{
ResourceBundle bundle
= ResourceBundle
.getBundle( "myResource" );
logger.setResourceBundle(bundle);
logger.info( "Resource Bundle "
+ logger.getResourceBundleName());
}
}

public class GFG {
private static Logger logger
= Logger.getLogger(

.getName());
public static void main(String args[])
{
ResourceBundle resbundle
= ResourceBundle.getBundle( "resourceBundle" );
logger.setResourceBundle(resbundle);
System.out.println( "Resource Bundle Name - "
