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()
.

, optionally including upperBound

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 elements outside its range.

The returned multiset will throw an IllegalArgumentException

This method is equivalent to
