> The **`Vector` class** is a growable array of objects. The elements of `Vector`  can be accessed using an integer index and the size of a `Vector` can be increased or decreased.  Read more about `Vector` [here](https://docs.oracle.com/javase/8/docs/api/java/util/Vector.html). 

The **`iterator` method** will return an `iterator` for the elements of the `Vector` object.

# 
#  Syntax

```java
public Iterator<E> iterator()
```

This method doesn't take any arguments. 

This method returns an `iterator` for the elements of the `Vector`. In the returned iterator, the elements are returned from index 0.

##
## Code

import java.util.Vector;
import java.util.Iterator;
class IteratorExample {
    public static void main( String args[] ) {
        Vector<Integer> vector = new Vector<>();
        vector.add(1);
        vector.add(2);
        vector.add(3);
        vector.add(4);
        Iterator<Integer> itr = vector.iterator();
        System.out.println("The elements of the vector is ");
        while(itr.hasNext()) {
          System.out.print(itr.next() + " , ");
        }
    }
}

In the code above,

* In line number 1: We import the `Vector` class.

* In line number 4: We create a new `Vector` object with the name `vector`.

* From line numbers 5 to 7: We add four elements(`1,2,3,4`) to the `vector` object using the `push` method.

* In line number 10: We use the `iterator` method to get an `iterator` for the elements of the `vector`.

* Then we print the elements of the iterator using the `while` loop. We use the `hasNext` method of the iterator object to check if the iterator contains more elements. We use the `next` method to get the next available element in the iterator.

What is the Vector.iterator method in Java?

The Vector.iterator method in Java returns an iterator for Vector elements, enabling sequential access starting from index 0.
