Vector elements() Method in Java

The java.util.vector.elements() method of Vector class in Java is used to get the enumeration of the values present in the Vector. 

Syntax:

Enumeration enu = Vector.elements()

Parameters: The method does not take any parameters. 

Return value: The method returns an enumeration of the values of the Vector. 

Below programs are used to illustrate the working of the java.util.Vector.elements() method: 

Program 1:

Java

// Java code to illustrate the elements() method
import java.util.*;

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

        // Creating an empty Vector
        Vector<String> vec_tor = new Vector<String>(5);

        // Inserting elements into the table
        vec_tor.add("Geeks");
        vec_tor.add("4");
        vec_tor.add("Geeks");
        vec_tor.add("Welcomes");
        vec_tor.add("You");

        // Displaying the Vector
        System.out.println("The Vector is: " + vec_tor);

        // Creating an empty enumeration to store
        Enumeration enu = vec_tor.elements();

        System.out.println("The enumeration of values are:");

        // Displaying the Enumeration
        while (enu.hasMoreElements()) {
            System.out.println(enu.nextElement());
        }
    }
}

Output:

The Vector is: [Geeks, 4, Geeks, Welcomes, You]
The enumeration of values are:
Geeks
4
Geeks
Welcomes
You

Program 2 : 

Java

import java.util.*;

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

        // Creating an empty Vector
        Vector<Integer> vec_tor = new Vector<Integer>(5);

        // Inserting elements into the table
        vec_tor.add(10);
        vec_tor.add(15);
        vec_tor.add(20);
        vec_tor.add(25);
        vec_tor.add(30);

        // Displaying the Vector
        System.out.println("The Vector is: " + vec_tor);

        // Creating an empty enumeration to store
        Enumeration enu = vec_tor.elements();

        System.out.println("The enumeration of values are:");

        // Displaying the Enumeration
        while (enu.hasMoreElements()) {
            System.out.println(enu.nextElement());
        }
    }
}

Output:

The Vector is: [10, 15, 20, 25, 30]
The enumeration of values are:
10
15
20
25
30

Time complexity: O(n), // n is the number of elements in the vector.
Auxiliary space: O(n)
