The issue is that you declare the randomNumber variable twice, which is invalid in Java. The datatype of a variable (int in this case) should only be used when declaring a variable, when you want to simply change the value of an existing variable it should not be included.

So if you simply remove int from your third line of code like this:

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

Then your code will pass task 3.
