Could be simplified, eg:

public int getSecondNumber() {
    ArrayList<Integer> arr = getFavouriteNumbers();
    if (arr.size() > 1) {
        return arr.get(1);
    } else {
        // Handle the case where the array does not have a second element
        // This could be returning a default value or throwing an exception
        return 0; // or throw new IllegalStateException("List does not have enough elements");
    }
}
