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 …

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

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.

Essentially, there are only two ways to iterate over a list: by using an index or by using an iterator. The enhanced for loop is just a syntactic shortcut introduced in Java 5 to avoid the tedium of explicitly defining an iterator.

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.

Dec 13, 2024 · In Java, the ArrayList.forEach() method is used to iterate over each element of an ArrayList and perform certain operations for each element in ArrayList. Example 1: Here, we will use the forEach() method to print all elements of an ArrayList of Strings.

Jul 18, 2024 · Throughout this article, you’ll learn how to use iterator in the Java Collections framework to traverse elements in collections such as List, Set, Map and Queue. You know, there are several ways to iterate collections in Java, but using iterator is the most basic and original.

The ListIterator interface provides methods to iterate over a list in both directions (forward and backward) and allows for the modification of elements during iteration. It is available only for lists. 2. Common Methods. boolean hasNext(): Returns true if the list iterator has more elements when traversing the list in the forward direction.

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"); .

The ListIterator is a part of Java’s Collections framework and is used to traverse and manipulate elements in a List in both forward and backward directions. It can be used with implementations of the List interface, such as ArrayList , LinkedList , etc.
