What are advanced iterators in Java collections?

Advanced iterators in Java collections include features like the Iterator, ListIterator, and Spliterator, which allow for more complex traversal and manipulation of data.

Can you explain how ListIterator differs from Iterator?

Certainly! ListIterator allows bidirectional traversal of a list, meaning you can move both forward and backward, while Iterator only allows forward traversal.

What is a Spliterator and when should I use it?

A Spliterator is designed for parallel processing of elements in a collection. You should use it when you want to split a collection into multiple parts for concurrent processing.

Are there any performance considerations when using these iterators?

Yes, performance can vary. For example, using a Spliterator can improve performance in parallel streams, but it may introduce overhead if not used correctly.

Can you provide an example of using a ListIterator?

Sure! Here's a simple example: ListIterator<String> iterator = list.listIterator(); while(iterator.hasNext()) { String item = iterator.next(); // process item }
