Sort list <Map <String, object >>

Question

I have an object below

 List<Map<String, Object>> listMap = new ArrayList<Map<String, Object>>(); 

How to sort this based on the value ("Object") on the map?

Answer 1

Create your own Comparator and use it.

 List<Map<String, Object>> listMap = new ArrayList<Map<String, Object>>(); Collections.sort(listMap,new Comparator<Map<String, Object>>() { public int compare(Map<String, Object> o1, Map<String, Object> o2) { //your logic goes here } }); 

Answer 2

Use your own comparator (you must implement this interface)
