public abstract class AbstractIntCollection extends Object implements IntCollection
IntCollections.
Read-only subclasses must override iterator()
and size(). Mutable subclasses
should also override add(int) and
IntIterator.remove.
All other methods have at least some base implementation
derived from these. Subclasses may choose to override
these methods to provide a more efficient implementation.| Modifier | Constructor and Description |

The returned array will be independent of me,
so that callers may modify that
returned array without modifying this collection.
When I guarantee the order in which
elements are returned by an iterator,
the returned array will contain elements in the
same order.toArray in interface IntCollectionpublic int[] toArray(int[] a)

the returned array will contain elements in the
same order.toArray in interface IntCollectiona - an array that may be used to contain the elementsCopyright © 2002-2013 The Apache Software Foundation. All Rights Reserved.
