Is it possible to get element from HashMap by its position?

Question

How to retrieve an element from HashMap by its position, is it possible at all?

Answer 1

Use a LinkedHashMap and when you need to retrieve by position, convert the values into an ArrayList.

LinkedHashMap<String,String> linkedHashMap = new LinkedHashMap<String,String>(); /* Populate */ linkedHashMap.put("key0","value0"); linkedHashMap.put("key1","value1"); linkedHashMap.put("key2","value2"); /* Get by position */ int pos = 1; String value = (new ArrayList<String>(linkedHashMap.values())).get(pos);
