The java.util.vector.lastElement() method in Java is used to retrieve or fetch the last element of the Vector. It returns the element present at the last index of the vector. 

Syntax:

Vector.lastElement()

Parameters: The method does not take any parameter. 

Return Value: The method returns the last element present in the Vector. 

Below programs illustrate the Java.util.Vector.lastElement() method: 

Program 1: 

Java

// Java code to illustrate lastElement()
import java.util.*;
 
public class VectorDemo {
    public static void main(String args[])
    {
        // Creating an empty Vector
        Vector<String> vec_tor = new Vector<String>();
 
        // Use add() method to add elements into the Vector
        vec_tor.add("Welcome");
        vec_tor.add("To");
        vec_tor.add("Geeks");
        vec_tor.add("4");
        vec_tor.add("Geeks");
 
        // Displaying the Vector
        System.out.println("Vector: " + vec_tor);
 
        // Displaying the last element
        System.out.println("The last element is: "
                           + vec_tor.lastElement());
    }
}

                    
Output:
Vector: [Welcome, To, Geeks, 4, Geeks]
The last element is: Geeks

Program 2: 

Java

// Java code to illustrate lastElement()
import java.util.*;
 
public class VectorDemo {
    public static void main(String args[])
    {
        // Creating an empty Vector
        Vector<Integer> vec_tor = new Vector<Integer>();
 
        // Use add() method to add elements into the Vector
        vec_tor.add(10);
        vec_tor.add(15);
        vec_tor.add(30);
        vec_tor.add(20);
        vec_tor.add(5);
 
        // Displaying the Vector
        System.out.println("Vector: " + vec_tor);
 
        // Displaying the last element
        System.out.println("The last element is: "
                           + vec_tor.lastElement());
    }
}

                    
Output:
Vector: [10, 15, 30, 20, 5]
The last element is: 5

Time complexity: O(1).
Auxiliary Space: O(1).
