count/delete/contains elements of collection using iterator, 

Hi,

I was wondering if there are functions to count in a collection using the
iterator, checking if an element is contained in a collection using the
iterator, deleting etc. I know these are simple while-loops, but I was
wondering if they were already avaiable in the library. I couldn't find
anything in the API docs.

thanks,

Peter

Yes ofcourse, I browsed through IteratorUtils and the .iterators-package, but I
couldn't find anything relevant. So I believe it isn't there, but I asked it to
be sure anyway.

thanks,

Have you already looked at the jakarta.commons.collections-API?

If you are missing something in the JDK's collection API or you're 
wondering why the collection API is like it is, maybe the design-FAQs 
can help you:

CollectionUtils.size() did the trick

[collections] generally deals with iterators by asking you to convert them 
to a collection, for which we provide a method. Have a scan of 
CollectionUtils to see if that helps.
