I guess that you're mispelling "randomNumber"... you're writing "rando_N_Number".

You need to put the empty string first on the last line like:-

intAsString = "" + randonNumber;

If you don't put the empty string first Java tries to do an addition instead of the concatenation which is what you require and obviously your random number + an empty string cant be done so results in an error.
