Orderofkey-valuepairsinHashMap

If two hashmaps have exact same set of key-value pairs, will I always get data in same order while iterating on two hashmaps?

Map map1 = new HashMap<>();
Map map2 = new HashMap<>();
map1.put("a1","b1");
map1.put("a2","b2");
map1.put("a3","b3");
map2.put("a1","b1");
map2.put("a2","b2");
map2.put("a3","b3");

for (Map.Entry e : map1.entrySet()) {
    System.out.println(e.getKey());
}
for (Map.Entry e : map2.entrySet()) {
    System.out.println(e.getKey());
}

If map1's iteration look like (a1,a2,a3), will map2's iteration also be like (a1,a2,a3)?

I know that bucket index is calculated using hash of key, but I am not sure if same index will be returned always.

You can never rely on order in case of Hashmap.If you want to maintain insertion order use LinkedHashMap and for sorted order use TreeMap
