Well right away, I need to thank you. Even though I urge to say that for me it not the suitable answer for the task we are beeing asked. I just feel it's not the gentleman way shown but, what do I know. My tries of an right solution the guardian didnt let pass, eventhough when I testes my code, the output was what I thought it should be right. Here I present you all my thoughts of an correct answer, that didnt pass:

BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
        ArrayList<String> fjal= new ArrayList<>();
        ArrayList<String> erg = new ArrayList<>();

        for (int i = 0; i < 5; i++) {
            fjal.add(bf.readLine());
        }

        fjal.remove(2);

        for (int i = fjal.size()-1; i >= 0; i--) {
            erg.add(fjal.get(i));
        }
        System.out.println(Arrays.asList(erg));

At the first step of the cycle (line 28): i = 0; 4-i = 4; list1.get(4) - do you have an element with index 4 in the list? No.
