please help!!!!!

im stuck on this part of the code challenge

"Now limit the range of the randomNumber variable from 0 to 9. Use the version of 'nextInt()' that has a parameter that specifies how many numbers to choose from."

i input this data

"Random randomGenerator = new Random(); int randomNumber = randomGenerator.nextInt(9); answer = Integer.toString(randomNumber);"

and it still says im wrong!!

make randomGenerator.nextInt(9) to randomGenerator.nextInt(10)

Because Random 0 to 9 counts to 10.

try using

 int randomNumber = randomGenerator.nextInt(10)

IIRC the argument passed to the nextInt function is exclusive, so you will get 0-9 by passing in 10, but only 0-8 if you pass in 9.

also you are missing the data type of your answer variable at this line

 answer = Integer.toString(randomNumber);

you need to declare it as a String
