Based on my testing, Tailer will only print a line when you've added a newline to the file. So try sudo echo "Hello\n" >> log.txt

Also note that if you call create, you start a thread but have no handle on it. Hence why you had to have a while/true loop.

You could try this instead:

public static void main(String[] args) {
    TailerListener listener = new MyListener();
    Tailer tailer = new Tailer(new File("log.txt"), listener, 500);        
    tailer.run();
}
