2,017 PointsStuck on the Random generator
On the challenge after the Random generator part for it asks me to
"Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: Use the toString() method of the Integer class."
It's thrown me off completely as I try to enter
Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(10); answer = Integer.toString(intAsString);
I feel although I'm not learning what I'm supposed to and it feels like I'm just copying what the instructor does on his screen, so when I get asked this I'm completely unsure of what to do.

// here you're initializing the class
Random randomGenerator = new Random();
// this gets your random int and saves it to an int variable
int randomNumber = randomGenerator.nextInt(10);
/*this line creates a String variable called intAsString which will hold a string
representation of your int. You are calling the toString() on the Integer class
to which you should be passing an integer to be converted into a string.
In this case that integer is contained within the randomNumber variable */
String intAsString = Integer.toString(randomNumer);

Courses Plus Student 641 PointsYes, I know the feeling. Some sections I am able to get through, but this certainly knocked me for 6. I must of been adding different variations for the last 2 hours. Yes, crazy I know. Don't worry Ben. We will get there. Trust in Treehouse. :-)
