I have the following method to remove a String from an ArrayList. when I

public void removePerson(String name)

       Iterator it = person.iterator();

It is impossible to say what you are doing wrong. Would you please stop posting random snippets, but short(!), complete(!), real code(!)? Where does "person" come from in that code? Also, AT WHICH LINE DOES THE EXCEPTION HAPPEN? We don't operate a psychic hotline here. Provide the complete error message as given by the compiler. Don't type it in, copy-and-paste it. Relate it to the source code.

Also, people expect that you do some work on your own. We are not your remote debuggers. If you look at the error message you will see that it contains a line number and file name and lists the type which couldn't be casted. You did look at the error message, didn't you? Look at the mentioned source code line. It is in your source code (the code we probably don't have).

Thank you Thomas - I couldn't have put it better.
