Method Details
- 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().
  
  Specified by:
  
  rem in interface CharCollection
  
  See Also:
  
  Collection.remove(Object)
- size
  
  public int size()
  
  Specified by:
  
  size in interface Collection<Character>
- isEmpty
  
  public boolean isEmpty()
  
  Specified by:
  
  isEmpty in interface Collection<Character>
- contains
  
  public boolean contains(char o)
  
  Description copied from interface: CharCollection
  
  Returns true if this collection contains the specified element.
  
  Specified by:
  
  contains in interface CharCollection
  
  See Also:
  
  Collection.contains(Object)
- 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.
  
  Specified by:
  
  iterator in interface CharCollection
  
  Specified by:
  
  iterator in interface CharIterable
  
  Specified by:
  
  iterator in interface Collection<Character>
  
  Specified by:

  Returns:
  
  a type-specific iterator on the elements of this collection.
  
  See Also:
  
  Iterable.iterator()

- remove
  
  @Deprecated public boolean remove(Object k)
  
  Deprecated.

- toCharArray
  
  public char[] toCharArray()
  
  Description copied from interface: CharCollection
  
  Returns a primitive type array containing the items of this collection.
