Yes, but: the Map interface itself has no defined order: "Some map implementations, like the TreeMap class, make specific guarantees as to their order; others, like the HashMap class, do not." So, if you encounter a "Map" (not a TreeMap or LinkedHashMap), you must not depend on any key ordering ... And most Map implementations used are in fact neither TreeMap nor LinkedHashMap.
