Part 2: interface iterator

[EurasianVixen]

Does anyone know if we are suppose to fill in the missing bodies of methods hasNext() and next()?
Are we suppose to print ALL tags for TagIterator including things like </a> and </b>?
Don't we need to store the tags into a vector or list of some sort before we can iterate thru it?
Who here understands A2?!

i think so.

that's what i was wondering. but it doesn't say we can't, so maybe we can.

that's what i'm wondering as well.

5. You must not use any sort of list to hold the tags--process them one at a time, as you find them.

[glow=orange,2,300]How do we add an object to Iterator without using a list, one at a time? PLEASE HELP![/glow]

i think i get it now, but i didn't try it out yet. i think ur only supposed to start processing stuff when next() is called. so u don't use an actual Iterator, but each time next() is called, u find the next tag and return it.

So you don't need to make an object Iterator?
Such as: Iterator it = new Iterator?
