Varun, not quite. Your random number is fine. But the challenge wants you to convert the number to a String, using the procedure shown in the video.

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

String intAsString = randomNumber + "";

The concatenation of a number and a String is a String. The trick is to use the empty String: ""

P.S., the spaces don't matter, but it is a good idea to omit them!

For challenge 1 this is correct:

Random randomGenerator = new Random();

Your () need be next to Random with no spaces
