Finding the second smallest integer in array

Question

We are required in our assignment to find the second smallest integer in one array recursively. However, for the sake of understanding the subject more, I want to do it iter

Answer 1

How about this?

   int[] result = Arrays.asList(-3, 4,-1,-2).stream()
            .reduce(new int[]{Integer.MIN_VALUE, Integer.MIN_VALUE},
                    (maxValues, x) -> {
                        if (x > maxValues[0]) {
                            maxValues[1] = maxValues[0]; //max becomes second max
                            maxValues[0] = x;
                        }
                        else if (x > maxValues[1]) maxValues[1] = x;
                        return maxValues;
                    }
                    , (x, y) -> x);
