Hi there,

The last task requires you to create a new variable called intAsString of type String. Assign into that the result of adding an empty string to randomNumber.

Make sense?

Steve.

I tried: 

Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(intAsString);
String intAsString = randomnumber + "";

Did not work so what am I missing?

Don't put intAsString in your nextInt method. Pass in the number 10.

Made the change:

Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(10);
String intAsString = randomnumber + "";

Still some problem though

Your variable is called randomNumber not randomnumber. You typo'd the last line. :smile:

If you copy your code in and hit the Preview button, it'll show you where your syntax errors are. This one showed up in there. Might help you progress more quickly rather than waiting for a reply in here.

Glad you got going again! :+1:
