No, I just meant that the original code WILL throw an
ArrayIndexOutOfBoundsException if it doesn't find a space.
Right here in the String#charAt method, when i reaches wholeName.length():

      for (int i = 0; i <= wholeName.length(); i++){
          if (wholeName.charAt(i)== ' '){

and bilsh probably wants to avoid it.
