Java




// Java code to illustrate removeLast()
import java.io.*;
import java.util.LinkedList;
 
public class LinkedListDemo {
    public static void main(String args[])
    {
        // Creating an empty LinkedList
        LinkedList<String> list = new LinkedList<String>();
 
        // Use add() method to add elements in the list
        list.add("Geeks");
        list.add("for");
        list.add("Geeks");
        list.add("10");
        list.add("20");
 
        // Displaying the list
        System.out.println("LinkedList:" + list);
 
        // Remove the tail using removeLast()
        System.out.println("The last element is removed: " + list.removeLast());
         
        // Displaying the final list
        System.out.println("Final LinkedList:" + list);
         
        // Remove the tail using removeLast()
        System.out.println("The last element is removed: " + list.removeLast());
 
        // Displaying the final list
        System.out.println("Final LinkedList:" + list);
    }
}
Output: 
LinkedList:[Geeks, for, Geeks, 10, 20]
The last element is removed: 20
Final LinkedList:[Geeks, for, Geeks, 10]
The last element is removed: 10
Final LinkedList:[Geeks, for, Geeks]

 

Time complexity of removeLast() : O(1)
