![]() ("Original List before deleting elements") MyLinkedList.add(2, "X") //This will add C at index 2 LinkedList myLinkedList = new LinkedList() Output of program is shown below the java code. Then we demonstrate use of getFirst() and getLast() methods. Then modifying the list using remove(), removeLast() and remove(Object o) methods. Here we are creating LinkedList named myLinkedList and adding objects using add(), addFirst() and addLast() methods as well as using index based add() method, then printing all the objects. Java Program to demonstrate use of all above methods described above. RemoveFirst( ) or pollFirst( ) or remove() The second constructor builds a linked list that is initialized with the elements of the collection c. The first constructor builds an empty linked list. LinkedList has the two constructors shown here: iLinkedList( ) Keep in mind that a LinkedList may iterate more slowly than an ArrayList, but it's a good choice when you need fast insertion and deletion. We are removing element B from the middle of the LinkedList which will just change node value of element A’s node to point to node C. ![]() There are three elements in LinkedList A, B and C. Below diagram shows how LinkedList storing values. Here Node is storing values of next node while data stores the value it is holding. Linked list has a concept of nodes and data. This linkage gives you new methods (beyond what you get from the List interface) for adding and removing from the beginning or end, which makes it an easy choice for implementing a stack or queue.
