Answer 1

I don't know Java too well, but it seems to me that this if statement goes only once and changes the first encountered number. Perhaps you shouldn't use "else" here.
Or think of doing it in a loop or something.

Answer 2

That's it, use a switch without any break instead! (any it's obviously required to start with the ten!)
