[~belugabehr] in that case ,if we add loop control inside Iterator ,that is not
so beautiful .maybe we should only extend the offset of begining loop. just
like below:
{code:java}
//代码占位符
final List list = Arrays.asList("1", "2", "3","4","5");
final LoopingListIterator loop = new LoopingListIterator<>(list,2);
for (int loops = 0;loops < 3*list.size();loops++)
{ System.out.print(loop.next()+", "); }
{code}
{code:java}
//代码占位符
3, 4, 5, 1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 1, 2,
{code}

David Mollitor commented on COLLECTIONS-698:
I was only interested in the read-only case. Add and Remove are optional
operations.

hi [~belugabehr] ,what does the parameter loops mean?
for your example
if a list has 3 items (1,2,3) then \{{LoopingListIterator(list, 1, 2)}} would
iterate: (2,3,1,2,3,1)?

As always, if I have time. I put it out there in the hopes that it piques
someone's interest. Good starter for a new contributor.
