int randNumber = randomGenerator.nextInt(10);

Hi there!  I wish I knew what you were trying that's failing, but I can already spot one error.  Your randNumber is supposed to be randomNumber as required by the challenge specifications.  
Java has something we call type inference.  Some languages cannot add a string and a number together.  But if you try to do this in Java, it understands that what you want is a string and will convert the result to a string.  So we're going to use this trick:
```java
Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(10);
String intAsString = randomNumber + "";
```
By adding an empty string to our randomNumber it will convert the result to a string and store it back into intAsString.

Hope this helps! :sparkles:
