HashMap can keep always the same order?

  • Difference between HashMap, LinkedHashMap and TreeMap 16 answers

    • 如果您使用LinkedHashMap，则顺序将保持不变（即，默认情况下，键将始终按照插入到Map中的顺序迭代）。

    If the keys and values are always the same, the map size is the same, and the HashMap is initialized in the same way, then yes. However for guaranteed iteration order, use a LinkedHashMap .
