Iter.remove() Method Error

Question

I am having some trouble implementing the iterator.remove() method correctly. I am trying to use the method to remove certain strings from an ArrayList of strings, but every time I try using an iterator (and the iterator.remove() method), I get an error titled "Check For Comodification". I am posting my code below for reference. Appreciate the help!

        Iterator<String> iter= myWords.iterator();
        while(iter.hasNext()){  
            String current= iter.next();
            for(int i=0;i<current.length();i++){
                if(current.charAt(i)==mostFrequentChar){
                    iter.remove();
                    break;
                }
            }
        }

Looks okay. What error do you get exactly, and at which line? — Thilo, Feb 16 '15 at 00:35
Is it possible that the iterator method is returning a _singletonish_ object that could be being modified elsewhere at the same time? — ttacon, Feb 16 '15 at 00:36
@user114241 No. Each call to `iterator` returns a new iterator, per the documentation. — user253751, Feb 16 '15 at 00:37

"Check For Comodification" usually means that something is already modifying the Collection at the same time while iterating over it. Check this out.
