I don't understand the question about making a string

The randomNumber variable is currently being stored as a integer. The question asks that it be converted to a String instead. There are a number of ways to do this. As per the video, you could simply add an empty String to the integer, which will convert it to a String, like this:

String intAsString = randomNumber + "";

Another solution is:

String intAsString = Integer.toString(randomNumber);
