I have a question about the Code Challenge:Using the Random class. Not understanding the last part. Please help.

"Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: "Moosh" them together like in the video!"

I've watched the video 4 time now. Still not understanding what to do.

RandomTest.java 
Random randomGenerator;

Hey,

There are a couple of ways to do it. Except the easiest way is this. If you take an integer and you add a string to it. It will put the entire variable in string form. So it converts the int to a string for you.

Random randomGenerator;

randomGenerator = new Random();

int randomNumber = randomGenerator.nextInt(10);

String intAsString = randomNumber + "";

OR

----Integer.toString(number)----
String intAsString = Integer.toString(randomGenerator

OR
----String.valueOf(number)----
String intAsString = String.valueOf(randomNumber )

All three of those work in different ways, but produce the same result.

Let me know if you have any questions on any one specific one and I can definitely elaborate.

Thanks!

Thank you! I did the first one you have there( String intAsString = randomNumber + ""; ), but for some reason it didn't work the first time.
