Java Vector addElement() Method

The addElement() method of Java Vector class is used to add the specified element to the end of this vector. Adding an element increases the vector size by one.

Syntax:

Following is the declaration of addElement() method:

Parameter:

Parameter	Description	Required/Optional
e	It is the element which will be added to the vector.	Required

Returns:

The addElement() method does not return anything because its return type is void.

Exceptions:

Compatibility Version:

Java 1.2 and above

Example 1:

import java.util.Vector;
public class VectorAddElementExample1 {  
	public static void main(String arg[]) {
		//Create an empty Vector with an initial capacity of 3      
	      Vector<String> vc = new Vector<>(3);
	      //Add elements in the vector by using add() method
	      vc.add("A");
	      vc.add("B");
	      vc.add("C");	      
	      //Print all the elements of a Vector
	      System.out.println("--Elements of Vector are--"); 	      
	      for (String str : vc) {         
	         System.out.println("Element= " +str);
	      }
	      //Add new element
	      vc.addElement("JavaTpoint");
	      //After addition, print all the elements again 
	      System.out.println("---Elements after addition--- "); 	      
	      for (String str : vc) {         
	         System.out.println("Element= " +str);
	      }
      }
}

Output:

--Elements of Vector are--
Element= A
Element= B
Element= C
---Elements after addition--- 
Element= A
Element= B
Element= C
Element= JavaTpoint

Example 2:

import java.util.Vector;
public class VectorAddElementExample2 {  
	public static void main(String arg[]) {
		//Create an empty Vector with an initial capacity of 3      
	      Vector<Integer> vc = new Vector<>(3);
	      //Add elements in the vector by using add() method
	      vc.add(101);
	      vc.add(-201);
	      vc.add(301);	      
	      //Print all the elements of a Vector
	      System.out.println("Elements of Vector are: "+vc); 	      
	      //Add new element
	      vc.addElement(-5001);
	      //After addition, print all the elements again 
	      System.out.println("Elements of vector after addition: "+vc); 	      
            }
}

Test it Now

Output:

Elements of Vector are: [101, -201, 301]
Elements of vector after addition: [101, -201, 301, -5001]
