LinkedList removeLast() Method in Java

The Java.util.LinkedList.removeLast() method is used to remove the last element from the LinkedList. This method also returns the element after removing it.
Syntax:

LinkedList.removeLast()

Parameters: This function does not take any parameters.
Return Value: The method returns the last element or the element present at the tail of the list.
Below program illustrate the Java.util.LinkedList.removeLast() method: 

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)
