Answer 1

public class DigitCount {

    public static int extractdigitcount(int n) {
        if (n < 0) n *= -1;
        if (n == 0) return 1;
        int count = 0;
        while (n > 0) {
            ++count;
            n /= 10;
        }
        return count;
    }

    public static void main(String[] args) {
        System.out.println(extractdigitcount(1200));
        System.out.println(extractdigitcount(-1200));
        System.out.println(extractdigitcount(-359));
    }
}
