for loop overextending index

I'm attempting to iterate through the EditText "name" and check the letters so see if they match any of the letters in the objects of the array uNamesList. If they do I want to break out of the loop and return the placement of the object that had the matching letter. At the moment I am getting this error, anyone know what might be wrong?

 java.lang.StringIndexOutOfBoundsException: length=9; index=9

    uNamesList.add("bob");
    uNamesList.add("mike");
    uNamesList.add("sike");
    uNamesList.add("othername");
    uNamesList.add("name");




public int getName(EditText name) {
    int match = 10;
    for (int i = 0; i < name.toString().length(); i++) {
        for (int o = 0; o < uNamesList.size(); o++) {
            char cLetter = name.toString().charAt(i);
            String uName = (String)uNamesList.get(o);

            char uLetter = uName.charAt(i);
            if (cLetter == uLetter) {
                match = o;
                break;

            }
        }
        if(match!= 10){
            break;
        }

    }
    return match;

}
