Hey Tremayne! Right now you're creating a String array object named 'randomNumber' and setting it equal to an empty set of curly braces. Instead, we need to create a String object named 'intAsString' and set it equal to our 'randomNumber' int object:

String intAsString = randomNumber;

But since 'intAsString' is a String, we need to cast our 'randomNumber' int to a String. An easy way to do this is to just add an empty String to our 'randomNumber':

String intAsString = randomNumber + "";

Hope that helps!
