Multiset
If the element set supports any removal operations, these necessarily cause all occurrences of the removed element(s) to be removed from the multiset. Implementations are not expected to support the add operations, although this is possible.
A common use for the element set is to find the number of distinct elements in the multiset:
elementSet().size()
.

itself. The returned multiset is a view of this
multiset, so changes to one will be reflected in the other. The returned multiset supports all
operations that this multiset supports.
The returned multiset will throw an IllegalArgumentException
on attempts to add

This method is equivalent to tailMultiset(lowerBound,
