Usage

From source file:Main.java

    Map<String, Object> map = new LinkedHashMap<String, Object>();

    List<String> keyList = new ArrayList<String>(yourMap.keySet());
    List<String> valueList = new ArrayList<String>(yourMap.values());
    Set<String> sortedSet = new TreeSet<String>(valueList);

    Object[] sortedArray = sortedSet.toArray();
    int size = sortedArray.length;

    for (int i = 0; i < size; i++) {
        map.put(keyList.get(valueList.indexOf(sortedArray[i])), sortedArray[i]);
    }/*  ww w  . j a  v  a  2  s  .c  o m*/

    Set ref = map.keySet();
    Iterator it = ref.iterator();
