What is the difference between Iterator and ListIterator in Java?

What is the difference between Iterator and ListIterator in Java?

In Java, an Iterator allows you to traverse a collection in one direction, while a ListIterator can traverse in both directions.

Can you give me an example of how to use ListIterator?

Sure! Here's a simple example:

List<String> list = new ArrayList<>();
list.add("A");
list.add("B");
ListIterator<String> listIterator = list.listIterator();

while (listIterator.hasNext()) {
    System.out.println(listIterator.next());
}

What methods does ListIterator have that Iterator doesn't?

ListIterator has additional methods like add(), set(), and previous(), which allow more flexibility in list manipulation.

When should I use Iterator instead of ListIterator?

Use Iterator when you only need to traverse a collection in one direction and don't need to modify the list.
