import java.util.logging.Logger; 
  
public class GFG { 
  
    private static Logger logger 
        = Logger.getLogger( 
            GFG.class
                .getPackage() 
                .getName()); 
  
    public static void main(String args[]) 
    { 
  
        // Check output is to be 
        // sent to the logger's parent 
        boolean flag 
            = logger.getUseParentHandlers(); 
  
        // Log the flag value 
        logger.info("output sent to the"
                    + " logger's parent - "
                    + flag); 
    } 
}

在Eclipse IDE上打印的輸出如下所示-
