HashMap først ind først ud

Jeg har aldrig brugt den men LinkedHashMap lyder relevant.

fra docs:

Hash table and linked list implementation of the Map interface, with predictable iteration order. 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).
