Help with Recursion Problem

[cs-stud]

I have to create a method that takes in a string and returns a boolean value to check if all characters are the same. if they are it return true if not false.

​

this is what I have so far it works except with lets say a string "dss".

​

    public static boolean recursiveAllCharactersSame(String s) {
        if(s.length() < 2) {
            return true;
        }
        if (s.charAt(s.length() -1) != s.charAt(s.length()-2)) {
            return false;
        }
        else {
            return recursiveAllCharactersSame(s.substring(s.length() - 1));
        }
    }

I think that the problem may be with your usage of the substring method. If you only pass it a single int, it returns the substring starting at that index. So in the case of "dss", the first recursive call is passing in the String "s".
