Get first and last elements in LinkedList example

In this example we shall show you how to get the first and the last elements of a LinkedList. The LinkedList class provides methods for these operations. To get the first and the last elements of a LinkedList one should perform the following steps:

• Create a new LinkedList.
• Populate the list with elements, with add(E e) API method of LinkedList.
• Invoke the getFirst() API method of LinkedList, that returns the first element in this list.
• Invoke the getLast() API method of LinkedList, to get the last element in the list,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;
 
import java.util.LinkedList;
 
public class FirstLastElementsLinkedList {
 
  public static void main(String[] args) {
 
    // Create a LinkedList and populate it with elements
    LinkedList linkedList = new LinkedList();
    linkedList.add("element_3");
    linkedList.add("element_1");
    linkedList.add("element_5");
    linkedList.add("element_2");
    linkedList.add("element_4");
 
    // Object getFirst() method returns first element in LinkedList
    System.out.println("The first element of LinkedList is : " + linkedList.getFirst());
 
    // Object getLast() method returns last element in LinkedList
    System.out.println("The last element of LinkedList is : " + linkedList.getLast());
 
  }
}

Output:

The first element of LinkedList is : element_3
The last element of LinkedList is : element_4

 
This was an example of how to get the first and the last elements of a LinkedList in Java.
