How do i sort this based on the value ("Object") in 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 have to implement the given interface)
