import java.io.IOException;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;
import java.util.logging.StreamHandler;

public class App {

     static final Logger log = Logger.getLogger("com.sample.app.App");

     static void processData() {
          log.info("Started Processing Data");
          log.info("Finished processing data");
     }

     public static void main(String args[]) throws IOException {
          log.setUseParentHandlers(false);

          log.addHandler(new StreamHandler(System.out, new SimpleFormatter()));

          processData();
     }
}
