Ascending order sorting a HashMap,TreeMap in Java

Here is the code

TreeMap<String, Integer> treeMap = new TreeMap<String, Integer>();
Iterator<Entry<String, Integer>> entries = map.entrySet().iterator();

while (entries.hasNext()) {
Entry<String, Integer> entry = entries.next();
treeMap.put(entry.getKey(), entry.getValue());
}

SortedSet<Map.Entry<String,Integer>> sm = new TreeSet<Map.Entry<String ,Integer>>();

sm =   treeMap; // This is sorted map in ascending order

Happy coding
