LinkedList class:

It provides a linked-list data structure. It uses doubly linked-list to store elements. It extends the AbstractList class and implements List  interface. We can use LinkedList class by importing java.util package.

Example:

import java.util.*;

public class ListDemo {

   public static void main(String args[]) {
      // create a linked list
      LinkedList ll = new LinkedList();
      // add elements to the linked list
      ll.add("F");
      ll.add("B");
      ll.add("D");
      ll.add("E");
      ll.add("C");
      ll.addLast("Z");
      ll.addFirst("A");
      ll.add(1, "A2");
      System.out.println("Original contents of ll: " + ll);

      // remove elements from the linked list
      ll.remove("F");
      ll.remove(2);
      System.out.println("Contents of ll after deletion: "
       + ll);
      
      

      
   }
}
