It is used to append the given element to the end. It is used to insert the given element at the beginning. Inserts the element at the specified element in the vector. Returns true if this list contains the specified element. It is used to append the specified element to the end of the vector. Some of the methods in the linked list are listed below: Method You can refer to the below image to get a better understanding of doubly linked list. Refer to the below image to get a better understanding of single Linked list.ĭoubly Linked List: In a doubly Linked list, it has two references, one to the next node and another to previous node. Singly Linked List: In a singly Linked list each node in this list stores the data of the node and a pointer or reference to the next node in the list. Java Linked List class uses two types of Linked list to store the elements: Syntax: Linkedlist object = new Linkedlist() Each link contains a connection to another link. Linked List : Linked List is a sequence of links which contains items. In the above code, it will return the names that we have added using add() method i.e: Jack Let us understand Array list with a programmatic example:ĪrrayList al=new ArrayList() // creating array list Trims the capacity of this ArrayList instance to be the list’s current size. Returns an array containing all the elements in the list. Return the index in this list of the last occurrence of the specified element, or -1 if the list does not contain this element. Inserts the specified element at the specified position. Some of the methods in array list are listed below: MethodĪppends the specified element to the end of a list. Also, the size of the list is increased dynamically if the elements are added more than the initial size. Let’s go into detail on each one of them:Īrray list: ArrayList is the implementation of List Interface where the elements can be dynamically added or removed from the list. Lists are further classified into the following: It is an interface that extends the Collection interface. Let’s learn about them in detail: Java collections: ListĪ List is an ordered Collection of elements which may contain duplicates. There are three components that extend the collection interface i.e List, Queue and Sets.
