Vector addElement() Method in Java

  • Last Updated : 02 Jul, 2021

The Java.util.Vector.addElement() method is used to append a specified element to the end of this vector by increasing the size of the vector by 1. The functionality of this method is similar to that of the add() method of Vector class.
Syntax: 
 

boolean addElement(Object element)

Parameters: This function accepts a single parameter element of object type and refers to the element specified by this parameter is appended to end of the vector. 
Return Value: This is a void type method and does not returns any value.
Below programs illustrate the working of java.util.Vector.add(Object element) method.
Program 1 : 
 

Java




// Java code to illustrate boolean addElement()
import java.util.*;
 
public class GFG {
    public static void main(String args[])
    {
 
        // Creating an empty Vector
        Vector<String> vec_tor = new Vector<String>();
 
        // Use add() method to add elements in the vector
        vec_tor.add("Geeks");
        vec_tor.add("for");
        vec_tor.add("Geeks");
        vec_tor.add("10");
        vec_tor.add("20");
 
        // Output the present vector
        System.out.println("The vector is: " + vec_tor);
 
        // Adding new elements to the end
        vec_tor.addElement("Last");
        vec_tor.addElement("Element");
 
        // Printing the new vector
        System.out.println("The new Vector is: " + vec_tor);
    }
}
Output: 
The vector is: [Geeks, for, Geeks, 10, 20]
The new Vector is: [Geeks, for, Geeks, 10, 20, Last, Element]

 

Program 2: 
 

Java




// Java code to illustrate boolean addElement()
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 in the vector
        vec_tor.add(1);
        vec_tor.add(2);
        vec_tor.add(3);
        vec_tor.add(10);
        vec_tor.add(20);
 
        // Output the present vector
        System.out.println("The vector is: " + vec_tor);
 
        // Adding new elements to the end
        vec_tor.addElement(50);
        vec_tor.addElement(100);
 
        // Printing the new vector
        System.out.println("The new Vector is: " + vec_tor);
    }
}
Output: 
The vector is: [1, 2, 3, 10, 20]
The new Vector is: [1, 2, 3, 10, 20, 50, 100]
