So in the code that you posted, you have declared an instance of the Random class. This is basically telling the computer, "Hey, I'm going to use the Random class, and I'm going to name this usage of it randomGenerator." However, the computer doesn't quite know what that means. It knows you will be using the Random class, but it doesn't know what exactly what to do with that information. So what you say next is "randomGenerator is going to generate a random number." So your code should look like this:

Random randomGenerator = new Random();

Good luck.

They are asking to create a new Random variable using the Random() constructor so:

Random randomGenerator = new Random();
