    HashMap doesn’t guarantee that the insertion-order is preserved.

    Use LinkedHashMap if you need such guarantee.

    This implementation differs from HashMap in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is normally the order in which keys were inserted into the map (insertion-order).
