Thank you. I think I was supposed to use only 1 list to solve this. Another task had that feedback when I verified my solution. Your code is concise and uses only 1 list. I'll follow that.

public class Solution {
    public static void main(String[] args) throws Exception {
        //write your code here
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        ArrayList<String> list = new ArrayList<String>();

        for(int i= 0; i<5; i++)
            list.add(reader.readLine());

        list.remove(2);

        for(int i = list.size(); i >=0; i--) System.out.println(list.get(i));
    }
}

I tested your code and it should pass no problem. There may be a glitch in the verify system on this problem, or some extra code that you wrote is failing the task. I provided the above code so you can take a look and implement some of the things in your own code. It does the same thing as your code. ArrayLists are dynamic and adjust accordingly when you add and remove items. On line 31 (your code), you don't need to add it to specific index (list.add(i,s );), instead just add it like i did on line 8 (my code). The ArrayList, when you don't sepcify the index number, will just add it to the very next spot and give it the next number available. The third element of an array is number 2 (first is 0, second is 1, third is 2, and so on). With ArrayList you can just call .remove and feed it the index you want removed (like i did not line 10). The remaining elements will shift down one number and fill in the blank spot. Next you can iterate through an arraylist by index using a for loop. See my example in line 12.

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); ArrayList<String> list = new ArrayList<String>(); for(int i= 0; i<5; i++) list.add(reader.readLine()); list.remove(2); for(int i = (list.size()-1); i >=0; i--) System.out.println(list.get(i)); that would be better
