I have some of values in my java program. I just stored those values in HashSet. I have stored it by for loop. The values iterating by loop has been ordered differently after the set formed. How can restrict this order change of HashSet as I get from the loop. Can anyone help me please?

    If you want the set to maintain the insertion order, you can use a LinkedHashSet:

    Implementation of the Set interface, with predictable iteration order. This implementation differs from HashSet in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order).

    Alternatively, if you want your set to be ordered, you can use a TreeSet.
