Michael,
thanks for your answer;
You're right with Integer.parseInt(....)
I realy read 2 good books of the Java-language, but I'm relatively knew
to programming with classes so I think it's normal that I stuck
sometimes on 'easy' things (I hope it's normal!).
Nevertheless, now it works & thanks a lot anybody who helped.
