How can I rewrite this to not have the Type mismatch error?

How do I rewrite this code to not have the Type Mismatch error on return Math.abs(i);

public static int[] countDigits(Scanner input) {
            int[] count = new int[10];
            int i = input.nextInt();
            while (Math.abs(i) >= 10 ) {
                i = i / 10;
            }
            return Math.abs(i);

This is the segment of code in particular that I need help with.It Reads integers from input, computing an array of counts for the occurrences of each leading digit (0-9).

Change your return type from int[] to int... because Math.abs returns one Integer. Not an array of Integers. Like this

public static int countDigits(Scanner input)
