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

public static int getSecondSmallest(int[] arr){
        int smallest = Integer.MAX_VALUE;
        int secondSmallest = Integer.MAX_VALUE;
        for(int i=0;i arr[i]){
                secondSmallest = smallest;
                smallest = arr[i];
            }else if (secondSmallest > arr[i] && arr[i] != smallest){
            secondSmallest = arr[i];
        }
            System.out.println(i+" "+smallest+" "+secondSmallest);
        }
        return secondSmallest;
    }

Just gave it a try with some of the test cases and it worked. Please check if it is correct!
