Hello!, u did not followed the instructions properly, this is the complete answer: Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(10); String intAsString = randomNumber + "";

1.first u create an instance of the Random() class called randomGenerator because u want to use the class methods. 2.next u create a integer called randomNumber which will hold a random value >> u use randomGenerator.nextInt(10) because u want to generate a random number from 0-9. lastly u convert a integer into a string by adding “”.

i hope it’s clearer now.
