        List<String> result = new ArrayList<String>();
        int lastIndex = 0;
        int index = str.indexOf(delimiter);
        while (index != -1) {
            result.add(str.substring(lastIndex, index));
            lastIndex = index + delimiter.length();
            index = str.indexOf(delimiter, index + delimiter.length());
        }
