Well there are couple of problems here. It wants a range of 0 to 9 for the random number generator. And you're producing either a 0 or a 1. Secondly, it gives you a variable name to assign the random number to which is intAsString. But you've declared a variable named f. This part is not needed. Also you have two declarations for randomGenerator which also isn't needed. Take a look at my solution:

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

String f=""; Random randomGenerator; Random randomGenerator= new Random(); int randomNumber=randomGenerator.nextInt(2); f= randomNumber+"";
