Its just an abbreviation to show the line is not complete.

You have to create your own TailerListener implementation which does
whatever you want with the lines added to the file. So for example you
could do something like the following:

    /**
     * TailerListener implementation.
     */
    public class ShowLinesListener extends TailerListenerAdapter {
        @Override
        public void handle(String line) {
            System.out.println(line);
        }
    }

Then create the Tailer with your implementation:

    TailerListener listener =3D new ShowLinesListener();
    Tailer tailer =3D Tailer.create(file, listener, delay);
