How to get multiple inputs?

Question

I would like to have multiple inputs in my code, but the second has always an error, saying unexpected source. I have searched a lot on the net, and all i found is that the scanner stops after one input. What to do? At the inserted code, the lines being a comment are the inactive things that dont work yet.

It finds the biggest common divider of 2 numbers

Answer 2

How did you test?
Two integers on a line with a space inbetween seems to work.
And two integers on separate lines seems to work. I get only messages in your language.

Answer 3

Ohh yeah, because i found it and repaired it. Now it works fine, thank you
