Write a Java program to iterate Vector collection using the iterator() method

The code you provided demonstrates how to iterate over the elements of a Vector using an Iterator in Java. Here's a breakdown of what the code does:

A Vector<String> object named vec_list is created.
Elements "Red", "Green", "Blue", "Yellow", and "Orange" are added to vec_list using the add method.
An Iterator object named itr is created by calling the iterator method on vec_list.
The message "Vector Elements are : " is printed using System.out.println.
The while loop is used to iterate over the elements of vec_list using the Iterator. The loop continues as long as itr has more elements (hasNext method returns true).
Inside the loop, the next method is used to retrieve the next element from itr, and it is printed using System.out.println.

Source Code

import java.util.*;
public class Iterator_Vector
{
	public static void main(String[] args)
	{
		Vector < String > vec_list = new Vector < String > ();
		vec_list.add("Red");
		vec_list.add("Green");
		vec_list.add("Blue");
		vec_list.add("Yellow");
		vec_list.add("Orange");
 
		Iterator itr = vec_list.iterator();
		System.out.println("Vector Elements are : ");
 
		while (itr.hasNext())
		{
			System.out.println(itr.next());
		}
	}
}

Output

Vector Elements are :
Red
Green
Blue
Yellow
Orange
