Hi there! The last step of the challenge does not require an array nor does it ask for one. Line one and line 5 of your code can safely be removed. It is looking for you to create a plain old string variable just like:

String hello = "Hello World!";

It wants the number that you've generated named randomNumber to be converted to a string and then assigned to the variable intAsString. As of right now, that variable (intAsString) does not exist in your code. Note that you can convert an integer to a string through something called "type inferencing". We do this by concatenating an empty string with an integer. The result is that the integer becomes a string.

You can find a demonstration of this at around 3:15 of this video

Hope this helps! :sparkles:
