Answer 1

It should be:

public class ZeroCounter {

    public static int numberOfDigits(int number) {
        //- Implementation goes here.
    }

    public static void main(String[] args) {
        int number;
        //- Initialize number variable.
        System.out.println("numberOfDigits(" + number + ")=" + numberOfDigits(number));
    }
}
