You've got this - come on!!

You've generated an instance of a generator that can create random numbers. We just called it randomGenerator.

Now, we want to call a method on that instance (use dot notation). The method is called nextInt(). That look like randomGenerator.nextInt();. Assign the returned value from that to randomNumber which is an integer.

That would look like;

int randomNumber = randomGenerator.nextInt();

Make sense - if not; ask questions here!

Steve.

Hi Ashley,

Would that be something like:

Random randomGenerator = new Random();

Let me know how you get on ...

Steve.

thank you now its saying Create a new int variable named randomNumber. Use the randomGenerator variable and its nextInt() method to get a random number. Do not set a range.

this whole challenge is confusing me.

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