public abstract class AbstractIntCollection extends AbstractCollection<Integer> implements IntCollection
In particular, this class provide iterator()
, add()
, remove(Object)
and
contains(Object)
methods that just call the type-specific counterpart.

strengthened in the corresponding type-specific class,
