I used the toString method and it caused a compilation error. I concatenated the integer with a String value...it worked

I'm not asking for help im trying to fill out a bug report

It's not a bug. You cannot call toString() on a variable of type int. You could do one of the following:

String intAsString = Integer.toString(randomNumber);

or

String intAsString = String.valueOf(randomNumber);

or

String intAsString = randomNumber + "";
