first off, String declarations are capitalized like so, String intAsString; To get the string value of an integer, you can do String intAsString = randomNumber + "";

or you can use the string method valueOf to get the value of the int as a string representation.

For Example, String intAsString = String.valueOf(randomNumber);

I would recommend the first solution where you concatenate the empty string to the number. If you do use valueOf, make sure you call it off of the static String class, like:

String intAsString = String.valueOf(randomNumber);

// or

String intAsString = Integer.toString(randomNumber);
