Could anyone Help with this?

Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable.

RandomTest.java 
Random randomGenerator = new Random();
 int randomNumber = randomGenerator.nextInt(10);

Hi Rob,

You start this challenge with the randomGenerator declared. The first task is to initialise it. You did that on one line, the alternative way is like:

Random randomGenerator;
randomGenerator = new Random();

Next you declare an integer and assign a random number to it using the nextInt() ethod, first without and next with the bounds checker. You've done that too:

int randomNumber = randomGenerator.nextInt(10);

Lastly, you need to declare a string and assign the above random number to it. The hint talks about 'mooshing' it - that means add an empty string to the int to cast it to a string:

String intAsString = randomNumber + "";

That covers the challenge, I think!

Steve.
