Get first and last elements from Java LinkedList

The first and last elements of a Linked List can be obtained using the methods java.util.LinkedList.getFirst() and java.util.LinkedList.getLast() respectively. Neither of these methods require any parameters.

A program that demonstrates this is given as follows

Example

 Live Demo

import java.util.LinkedList; public class Demo { public static void main(String[] args) { LinkedList l = new LinkedList(); l.add("John"); l.add("Sara"); l.add("Susan"); l.add("Betty"); l.add("Nathan"); System.out.println("The first element of the Linked List is : " + l.getFirst()); System.out.println("The last element of the Linked List is : " + l.getLast()); } }

The output of the above program is as follows

The first element of the Linked List is : John The last element of the Linked List is : Nathan

Now let us understand the above program.

The LinkedList l is created. Then LinkedList.getFirst() and LinkedList.getLast() are used to get the first and last elements of the linked list respectively. A code snippet which demonstrates this is as follows

LinkedList l = new LinkedList(); l.add("John"); l.add("Sara"); l.add("Susan"); l.add("Betty"); l.add("Nathan"); System.out.println("The first element of the Linked List is : " + l.getFirst()); System.out.println("The last element of the Linked List is : " + l.getLast());
