Below is a method which takes input as an unsorted map and returns a sorted one.
The task is accomplished by creating an anonymous java class.
For example: if original map is
{("sample1",58),("string3",34),("delta",85)}
The returned map would look like
{("delta",85),("sample1",58),("string3",34)}
public static> Map sortByValues(final Map map) { Comparator valueComparator = new Comparator () { public int compare(K k1, K k2) { int compare = map.get(k2).compareTo(map.get(k1)); if (compare == 0) return 1; else return compare; } }; Map sortedByValues = new TreeMap (valueComparator); sortedByValues.putAll(map); return sortedByValues; }
Let me know if you have a question.
