How to get value in ascending order from LinkedHashMap

Question

I am using function which returns key value pair in LinkedHashMap.

LinkedHashMap<Integer,String> lhm = new LinkedHashMap<Integer,String>();

  // Put elements to the map
  lhm.put(10001, "Stack");
  lhm.put(10002, "Heap");
  lhm.put(10003, "Args");
  lhm.put(10004, "Manus");
  lhm.put(10005, "Zorat");

Note: I cannot change LinkedHashMap to any other map in my code as the function is being used in several other functions.

I have also googled and tried to use TreeMap which gives us the desired result in ascending order. But, here in TreeMap key is in ascending order and not the values.

My requirement is mainly for values.

How can I get values in Ascending order.

Desired Output

10003, "Args"
10002, "Heap"
10004, "Manus"
10001, "Stack"
10005, "Zorat"

Thank you in advance !!!!

You need a comparator for this

  Comparator<Entry<String, String>> valueComparator = new 
                                  Comparator<Entry<String,String>>() { 
  @Override public int compare(Entry<String, String> e1, Entry<String, 
     String> e2) { 

     String v1 = e1.getValue(); String v2 = e2.getValue(); return 
     v1.compareTo(v2); 
 } 
};
