    Java and O(n log n)

     Collections.sort(arr);
        int minDiff = Integer.MAX_VALUE;
        for (int i = 1; i < arr.size(); i++) {
            int diff = Math.abs(arr.get(i) - arr.get(i - 1));
            if (diff < minDiff) {
                minDiff = diff;
            }
        }
        return minDiff;
