hey Moonlight! how is it going/ hope all is well!

I'll ask our guys in software what solution they have to your issues ... unfortunately, the filed I am in is a little bit different ... it's silicon ip field and semiconductors - I am not a coder

but I'll ask the guys to help you out with this ... let me check with our s/w engineers first ...

cheers!

thx considering

i didn?t go any further. if understood the prob, mayb could do smth. i believed it should b right. in case posting the codes

Code:

class LilitHw1

        static String Term = "implementation";

        public static void main(String[] args)

I'm not so familiar with java, but the problem is that java "doesn't know" who is "Konsole", check out whether you imported the lib (correctly). By the way, there is a link to the Konsole class implementation, try to place that above the LilitHw1 class.

Ciao.

Moonlight · 01.12.2004, 13:15

AvDav: thx so so much!! i had even translated german text in the given file, but forgot 2 add Konsole.class (no way 2 replace the hw1). finally no errors, but prog runned only 2 prove me that is working not the way it was supposed to!! after classes i?ll have only some hrs b4 the deadline..

Hey, Moonlight. Studierst du Informatik an der HU? Wenn, ja, dann können wir uns treffen, ich mache jetzt Bioinformatik an der TFH, und habe Ahnung in Java

Moonlight · 24.01.2005, 19:55

ja!!!!! ich studiere auch wirtschaft informatik an der hu!! und echt brauche hilfe mit java!!!! danke sehr! details over pm

Moonlight · 01.02.2006, 19:48

nevermind, the deadline missed
