Teraz znalazłem dla siebie odpowiednie rozwiązanie. Może mógłbym zrobić to lepiej, ale to mi na razie pomaga.
Znalazłem następujący blog:http://tfathy.blogspot.de/2009/03/reading-from-file.html
Kod działa w 100% metodą kopiuj i wklej i pomaga mi od teraz wykonać zadanie.
Może pomoże to również komukolwiek innemu.
Oto kod rozwiązania:
