What are List Iterators in Java?

Can you explain what List Iterators are in Java?

Sure! List Iterators in Java are special iterators that allow you to traverse a list in both directions, forward and backward.

How do they differ from regular iterators?

Unlike regular iterators, List Iterators can modify the list during iteration and can also access elements in both directions.

Can you show me a code example of using a List Iterator?

Absolutely! Here's a simple example:

import java.util.ArrayList;
import java.util.ListIterator;

public class ListIteratorExample {
    public static void main(String[] args) {
        ArrayList<String> list = new ArrayList<>();
        list.add("Apple");
        list.add("Banana");
        list.add("Cherry");

        ListIterator<String> iterator = list.listIterator();
        while (iterator.hasNext()) {
            System.out.println(iterator.next());
        }
    }
}

What methods are available in ListIterator?

ListIterator provides several methods like next(), previous(), hasNext(), hasPrevious(), add(), and remove().
