Method Details
-
contains
public boolean contains(int k)Description copied from class:AbstractIntCollection
Returnstrue
if this collection contains the specified element.This implementation iterates over the elements in the collection, looking for the specified element.
- Specified by:
contains
in interfaceIntCollection
- Overrides:
contains
in classAbstractIntCollection
- See Also:
Collection.contains(Object)
-
remove
public boolean remove(int k)Description copied from class:AbstractIntSet
Removes an element from this set.Note that the corresponding method of a type-specific collection is
rem()
. This unfortunate situation is caused by the clash with the similarly named index-based method in theList
interface. Delegates to the type-specificrem()
method implemented by type-specific abstractCollection
superclass.- Specified by:
remove
in interfaceIntSet
- Overrides:
remove
in classAbstractIntSet
- See Also:
Collection.remove(Object)
-
iterator
Description copied from interface:IntCollection
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 extendsCollection
.- Specified by:
