Does the collection obtained from the map.values () method preserve the insertion order?

Question

Does the collection obtained from the map.values () method preserve the insertion order?

I have a copy LinkedHashMap

. LinkedHashMap

preserves the order of insertion. I need to get the values of this card and I need them to be in the same order. So if I call a values()

method on this LinkedHashMap

one Collection

that I get from the method values()

guarantees the insertion order?
