Please! i need help with this section stage 2 learning the language. I am on the array section and i'm stuck

(this is what the challenge was)

Declare an int variable named 'numberOfFrogs' and set it to the number of elements in the array using the array's 'length' property.

(the last line was the answer i put in) String[] frogNames = { "mike", "ike", "tyke"}; String bestFrog = "mike"; int numberOfFrogs = randomGenerator.nextInt(frogNames.length);

(and here is the error message) JavaTester.java:24: cannot find symbol symbol : variable randomGenerator location: class JavaTester int numberOfFrogs = randomGenerator.nextInt(frogNames.length); ^ 1 error

Don't know exactly what the error is, but your task is simply to get the number of elements in the array. You however create a random number in the range of the array. int numberOfFrogs = randomGenerator.nextInt(frogNames.length); gives you a random number between 0 and 2 int numberOfFrogs = frogNames.length; gives you just 2.. all you need
