Hello, I was discussing with a student, she was trying to use the SortedMap interface but had trouble with tailMap() no being a strictly higher view from a key. The solution was to use NavigableMap instead of SortedMap because it provides more methods to get lower/higher subMap and entries from keys.
I think we can improve de documentation of SortedMap (the last section (Note:) of the overview) by rewriting it saying that NavigableMap provides a richer API instead of the current documentation that propose to add 1 or '\0' to the subMap() which is a ugly hack. regards, Rémi
