Iterator's method implementation

[Sambhavi Balasubramaniam]

Hi all,

I have a clarification on methods of Iterator interface. Iterator interface provides hasNext(), next() and remove() methods. From the Javadoc, class BeanContextSupport implements Iterator.

In collections like ArrayList, HashTable, HashSet, Vector we make use of those 3 methods to traverse through and remove objects. If you take ArrayList's hierarchy, I don't find BeanContextSupport in picture. In that case, which implementation does an ArrayList (or any collection) take for those 3 methods? Maybe a trivial question !!!

Thanks,
Sambhavi

Either java.util.ArrayList or java.util.AbstractList (the super class of ArrayList) may have a private inner class which is implemented from java.util.Iterator. In that case, it cannot be structured on JavaDoc, since JavaDoc is not supposed to provide the hierarchy structure for private inner class.
