LinkedList is a class that extends the AbstractSequentialList and implements List, Deque, Queue interfaces, which internally uses a doubly linked list to store data elements. ArrayList is a class that extends the AbstractList and implements the List interface that internally uses a dynamic array to store data elements. This article discussed the difference between ArrayList and LinkedList. The list is an interface of collection framework. The collection framework allows working with data structures such as lists, trees, maps and sets. LinkedList performs as a List and a Queue. Manipulating elements of LinkedList is faster than of an ArrayList. Manipulating elements of ArrayList is slower than of a LinkedList. LinkedList is a class that extends the AbstractSequentialList and implements List, Deque, Queue interfaces, which internally uses a doubly linked list to store data elements.Īccessing elements of ArrayList is faster than of a LinkedList.Īccessing elements of LinkedList is slower than of an ArrayList. Refer the below program.ĪrrayList is a class that extends the AbstractList and implements the List interface which internally uses a dynamic array to store data elements. The remove() method is used to remove an element out of the list.
The add() method can be used to add elements to the list. To access elements, the get() method is used. Therefore, the methods of the List interface can be used by ArrayList. The ArrayList class extends the AbstractList class that implements List interface. The capacity increases automatically, so the programmer can add elements to the list. An object created using ArrayList class is allowed to store a set of elements in the list. Unlike a normal array, the size of a dynamic array is not fixed. The ArrayList class is used to create dynamic arrays. Side by Side Comparison – ArrayList vs LinkedList in Tabular Form Similarities Between ArrayList and LinkedListĥ. LinkedList is a class that extends the AbstractSequentialList and implements List, Deque, and Queue interfaces, which internally use a doubly linked list to store data elements. That is the key difference between ArrayList and LinkedList. ArrayList is a class that extends the AbstractList and implements the List interface, which internally uses a dynamic array to store data elements. This article discusses the difference between ArrayList and LinkedList. They implement the collection interface and List interface. ArrayList and LinkedList are two classes in the collections framework. The list is an interface of Collection framework. It helps to work with data structures such as lists, sets, trees and maps.
Collections allow to store, update, retrieve set of elements. It serves as a container for a group of elements. It is a framework with a set of classes and interfaces. Programming languages such as Java has collections. Sometimes it is required to create arrays that can grow as needed. In a normal array, the array size is fixed.
