      • add

        public boolean add​(char k)
        Description copied from interface: CharCollection
        Ensures that this collection contains the specified element (optional operation).
        Specified by:
        add in interface CharCollection
        See Also:
        Collection.add(Object)

      • rem

        public boolean rem​(char k)
        Description copied from interface: CharCollection
        Removes a single instance of the specified element from this collection, if it is present (optional operation).

        Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

        rem in interface CharCollection

      • iterator

        public CharIterator iterator()
        Description copied from interface: CharCollection
        Returns a type-specific iterator on the elements of this collection.

        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 Collection.
