Chapter: Data Structures Last Updated: 28-08-2016 19:24:17 UTC

Program:

            /* ............... START ............... */
                
import java.util.LinkedList;

public class JavaRemoveFirstLastLinkedList {
	public static void main(String[] args) {

		// Create a LinkedList
		LinkedList<String> linkedlist = new LinkedList<String>();

		// Add elements to LinkedList
		linkedlist.add("Java");
		linkedlist.add("C#");
		linkedlist.add("C");
		linkedlist.add("Phython");

		// Displaying Elements before remove
		System.out.println("LinkedList Elements are:");
		for (String str : linkedlist) {
			System.out.println(str);
		}

		// Removing First element
		Object firstElement = linkedlist.removeFirst();
		System.out.println("\nElement removed: " + firstElement);

		// Removing last Element
		Object lastElement = linkedlist.removeLast();
		System.out.println("Element removed: " + lastElement);

		// LinkedList elements after remove
		System.out.println("\nList Elements after Remove:");
		for (String str2 : linkedlist) {
			System.out.println(str2);
		}
	}
}
                /* ............... END ............... */
        

Output

LinkedList Elements are:
Java
C#
C
Phython

Element removed: Java
Element removed: Phython

List Elements after Remove:
C#
C

Notes:

  • removeFirst() method to remove first and removeLast() method to remove last element from LinkedList.
  • public removeFirst(): Removes and returns the first element from this list.
  • public removeLast(): Removes and returns the last element from this list.
