In java 8, we got the new forEach() method to iterator over collections. Iterate the LinkedList using Java 8 forEach() Method Read LinkedList listIterator() method in Java 6. I have written a detailed article on the ListIterator metod of the LinkedList class. Iterate the LinkedList using ListIterator Also, we have remove() method in the LinkedList class, if you used the LinkedList.remove() method to remove an element while iterating over the list, you will get the ConcurrentModificationException. Note: It is always recommended to use the Iterator.remove() method for removing an element from a list while iterating on it. ![]() Iterating through LinkedList using Iterator interface. * A java program to iterate through LinkedList using Iterator interface. Please refer the following Java example to iterate over LinkedList using the basic for loop. We can write a simple for loop for the LinkedList and access the elements of the LinkedList using the get(int index) method. Iterate the LinkedList using basic for loop Iterate the LinkedList using Java 8 forEach() Method.Iterate the LinkedList using while loop.Iterate the LinkedList using Enhanced For Loop i.e.Iterate the LinkedList using basic for loop.There are multiple ways to iterate over the LinkedList. That’s why LinkedList is preferred when our frequent operation is insertion and deletion. LinkedList internally uses a doubly linkedlist for storing the variables. LinkedList class is present in the java.util package. ![]() There are multiple ways to iterate such as loops, using Iterator or using Java 8 syntax.Let’s see this ways to iterate over LinkedList in Java. In this tutorial, we will see how to iterate linkedList in java. Iterate the LinkedList using Enhanced For Loop i.e. ![]() Check out my blog for more captivating content from me. It is critical that you understand all of these methods and then determine which method is preferable for you, cleaner to use, and easier to read.Įmbark on a journey of learning! Browse 200+ expert articles on web development. In this article, we looked at six different/standard methods for looping through an array. You can write this in one line this way: scores.forEach((score) => console.log(score)) Īnd this will give us the same output as all previous methods: 22 Let's now use the while loop method to loop through the array: let i = 0 If we want to loop through an array, we can use the length property to specify that the loop should continue until we reach the last element of our array. If the condition is true, the code inside the while loop is executed. You can use a while loop to evaluate a condition that is enclosed in parenthesis (). How to Loop Through an Array with a While Loop in JavaScript We will use the following array for this article: const scores = In this article, we will go over the most commonly used so you can learn different approaches and understand how they work. There are numerous methods for looping through an array in JavaScript. Here's an interactive scrim about how to loop through an array in JavaScript: What are Loops in JavaScript?Ī loop is a type of computer program that allows us to repeat a specific operation a predetermined number of times without having to write that operation individually.įor example, if we have an array and want to output each element in the array, rather than using the index number to do so one by one, we can simply loop through and perform this operation once. ![]() Knowing that these single variables contain a list of elements, you might want to create a list of these elements so that you can perform individual functions with them and much more. It is an ordered list of values, and each value is referred to as an element, which is specified by an index. An array is a single variable used to store elements of different datatypes so that they can be accessed through a single variable.
