public abstract class AbstractIntCollection extends Object implements IntCollection
IntCollection
s.
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
