You can convert an integer in Java to a String by "Moosh"-ing or concatenating it together with an empty String (""). So for example you could try:

String intAsString = randomNumber + "";

The + operator is a shorthand in Java for the "Moosh"-ing or concatenating operator, so what this is doing is taking the randomNumber int and "moosh"-ing it with an empty String. This will result in a String where the text is that of the randomNumber. So for example, if randomNumber = 3, intAsString would be "3" after this statement.

This works for all Strings in general not just empty ones (so for example, I could code:

String intAndStringExample = randomNumber + "woohoo";

and expect that if randomNumber is an integer equal to 3 that intAndStringExample = "3woohoo".)

Hope this helps!
