I'm not sure what I'm doing wrong. It evaluates the numbers and when I run it in the out put window it shows the number from the println command but I still keep getting errors saying it should display a number. 
public class Solution {
    public static void main(String[] args) {
        displayClosestToTen(8, 11);
        displayClosestToTen(7, 14);
    }

    public static void displayClosestToTen(int a, int b) {
        // write your code here
        a = abs(a-10);
        b = abs(b-10);

        if(a > b){
            System.out.println(a);
        }else if(b > a){
            System.out.println(b);

        }else{
            System.out.println(a);
        }

    }

    public static int abs(int a) {
        if (a < 0) {
            return -a;
        } else {
            return a;
        }
    }
}
