Nov 1, 2022 · In Java, the spliterator() method of the LinkedList class returns a Spliterator that helps iterate over an element of the linked list. A Spliterator is a special type of iterator used to process elements in parallel processing of elements when used with conjunction in …

An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator's current position in the list.

In Java, there are multiple ways to iterate over a List, depending on your use case, Java version, and style preference. Here's a breakdown of the most common methods:

Jun 3, 2024 · Method 3: Using List iterator. ListIterator is an iterator in Java which is available since the 1.2 version. It allows us to iterate elements one-by-one from a List implemented object. It is used to iterator over a list using while loop. Syntax: ListIterator<data_type> variable = list_name.listIterator(); Below is the example of this method: Java

Apr 10, 2025 · In this article, we demonstrated the different ways to iterate over the elements of a list using the Java API. These options included the for loop, enhanced for loop, Iterator, ListIterator, and the forEach() method (included in Java 8). Then we learned how to use the forEach() method with Streams.

The listIterator() method returns a ListIterator for the list. To learn how to use iterators, see our Java Iterator tutorial. The ListIterator differs from an Iterator in that it can also traverse the list backwards.

Dec 13, 2024 · Explanation: In the above example, we use a ListIterator to iterate over an ArrayList of Strings i.e. “A”, “B”, “C”, and “D”. It prints each element of the list sequentially using the hasNext () and next () methods of the ListIterator.

Aug 4, 2022 · In Java, ListIterator is an interface in Collection API. It extends Iterator interface. To support Forward and Backward Direction iteration and CRUD operations, it has the following methods. We can use this Iterator for all List implemented classes like ArrayList, CopyOnWriteArrayList, LinkedList, Stack, Vector, etc.

Sep 11, 2022 · In the last tutorial, we discussed Iterator in Java using which we can traverse a List or Set in forward direction. Here we will discuss ListIterator that allows us to traverse the list in both directions (forward and backward). In this example we are traversing an ArrayList in both the directions. names.add("Shyam"); . names.add("Rajat"); .

ListIterator<Integer> iterate = numbers.listIterator(); // Using the next() method int number1 = iterate.next(); System.out.println("Next Element: " + number1); // Using the nextIndex() int index1 = iterate.nextIndex(); System.out.println("Position of Next Element: " + index1); // Using the hasNext() method .
