    String text = "A,B,C,D";

    String[] keyValue = text.split(",");

    Map<Integer, String> myMap = new HashMap<Integer, String>();
    for (int i = 0; i < keyValue.length; i++) {
        myMap.put(i, keyValue[i]);
    }//www .j  av a  2 s. c  o m

    Set keys = myMap.keySet();
    Iterator itr = keys.iterator();

    while (itr.hasNext()) {
        Integer key = (Integer) itr.next();
        String value = (String) myMap.get(key);
