Iterate over a vector using Enumeration

In the previous post, we have seen how to sort the vector. In this post, we will see how to iterate over a vector using enumeration.

Create a vector and add element to it. You can get the enumeration of specified vector by using elements() method. There are 2 methods which helps to iterate over the vector using enumeration.

• hashMoreElements() : Will check if vector has elements.
• nextElement(): Will get the next element.

Example:

import java.util.Enumeration;
import java.util.Vector;

public class VectorExmple {

	public static void main(String[] args) {
		
		Vector<String> car = new Vector<String>(3);   //it has capacity of 3
		car.addElement("BMW");
		car.addElement("Honda");
		car.addElement("Audi");
		car.addElement("Ferrari");
		car.addElement("Bugatti");
		
		System.out.println("All cars : "+car);
		Enumeration<String> en = car.elements();
		
		while(en.hasMoreElements()){
			System.out.println("Element : "+ en.nextElement());
		}
	}
}

Output:

All cars : [BMW, Honda, Audi, Ferrari, Bugatti] Element : BMW
Element : Honda
Element : Audi
Element : Ferrari
Element : Bugatti
