How do I sort HashSet?
Steps:Create new HashSet object.Store HashSet contents into ArrayList using inter-conversion constructor.Finally, invoke Collections. sort(al); method to sort elements in ascending order.Note: similarly elements can be sorted in descending order as well using Comparator.
Does HashMap maintain insertion order?
HashMap is implemented as a hash table, and there is no ordering on keys or values. TreeMap is implemented based on red-black tree structure, and it is ordered by the key. LinkedHashMap preserves the insertion order. Hashtable is synchronized, in contrast to HashMap.
