Hi BJORN,

"Declare an int variable named 'randomNumber' and, without setting a range, use the randomGenerator variable and its nextInt() method to get a random number"

In the first part of the challenge you must have written the line

Random randomGenerator = new Random();

Random is a special feature built inside Java that helps you get random numbers up until a specified number.

Now the second part

Random randomGenerator = new Random();

//declare a variable called randomNumber 
//I am breaking this to help you explain but as given by Jose above you can write it in one line too

int randomNumber;

//without setting a range, use the randomGenerator variable and its nextInt()
 randomNumber = randomGenerator.nextInt();

You first declare an integer variable called randomNumber. Pretty straightforward.

Next, as mentioned above Random is an inbuilt java feature and it has a special method called nextInt that fetches a new random number each time it is called. This method has a basic syntax

nextInt(range); //where range is the number up until where you wish to get the random number

So using the Random variable called randomGenerator we call the nextInt method, but as specified in the instruction we do not set the range and thus it is blank

A lot of the basics reflect back to core java. Though I am not sure if you are well versed with it but just a quick read will suffice.

Hope that helps. Ask again if you need help
