java: comparison of two simple distance calculation algorithms


It is the only method printMaxDistance_a or both methods printMaxDistance_b AND printMaxDistance_c better or respectively "more readable"? Thank you.

    public static void printMaxDistance_a(String s) {
        int first = 0;
        int second = 0;
        int max = 0;
        for (int i = 0; i < s.length(); i++) {
            for (int j = i + 1; j < s.length(); j++) {
                if (s.charAt(i) == s.charAt(j)) {
                    if ((j - i) > max) {
                        first = i;
                        second = j;
                        max = j - i;
                    }
                    break;
                }
            }
        }
        System.out.println(first + " " + second + " " + max);
    }

    public static void printMaxDistance_b(String s) {
        int first = 0;
        int second = 0;
        int max = 0;
        for (int i = 0; i < s.length(); i++) {
            int cur = printMaxDistance_c(s, s.charAt(i), i + 1);
            if (cur > max) {
                first = i;
                second = i + cur;
                max = cur;
            }
        }
        System.out.println(first + " " + second + " " + max);
    }

    public static int printMaxDistance_c(String s, char c, int j) {
        for (int i = j; i < s.length(); i++) {
            if (c == s.charAt(i)) {
                return i - (j - 1);
            }
        }
        return 0;
    }
