public interface CharSet extends CharCollection, Set<Character>
Set
; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens (again) iterator()
.

iterator()
Returns a type-specific iterator on the elements of this set.

remove(char k)
Removes an element from this set.

CharIterator iterator()
Note that this specification strengthens the one given in Iterable.iterator()
,
which was already strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Set
.

boolean remove(char k)
Note that the corresponding method of the type-specific collection is rem()
.
This unfortunate situation is caused by the clash
with the similarly named index-based method in the List
interface.
