true
iff I changed as a result of this call.
If a collection refuses to add the specified
element for any reason other than that it already contains
the element, it must throw an exception (rather than
simply returning false). This preserves the invariant
that a collection always contains the specified element after
this call returns.

The returned array will be independent of me,
so that callers may modify that

When I guarantee the order in which
elements are returned by an iterator
,
the returned array will contain elements in the
same order.
