    Java:

    public static int minimumAbsoluteDifference(List<Integer> arr) {
    if (arr == null || arr.size() < 2) {
      throw new IllegalArgumentException(
          "Array must contain at least two elements.");
    }
    Collections.sort(arr);
    //System.out.println(arr);
    int n = arr.size();
    int minAbsDiff = Integer.MAX_VALUE;

    for (int i = 0; i < n - 1; i++) {
      int abs = arr.get(i + 1) - arr.get(i);
      minAbsDiff = Math.min(minAbsDiff, abs);
    }

    return minAbsDiff;
  }
