Vector lastElement() Method in Java

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).
