In this shot, we will discuss the **`Deque.iterator()`** method in Java.

The `Deque.iterator()` method is present in the `Deque` interface inside the `java.util` package.

`Deque.iterator()` returns the iterator over the deque elements in the sequence they are present in.

#    
## Syntax
```
Iterator iterator()
```

## Parameters
The `Deque.iterator()` method doesn’t take any parameters.

## Return value
 
* `Iterator`: The iterator over the deque elements in the sequence they are present in.

## Code
Let's take a look at the following code snippet.

import java.util.*;
class Main 
{
public static void main(String[] args)
{
Deque<Integer> d = new LinkedList<Integer>();

d.add(2);
d.add(28);
d.add(6);
d.add(80);
d.add(21);
d.add(7);
d.add(15);

Iterator i = d.iterator();
System.out.print("The iterator values of deque are: ");
while (i.hasNext()) 
{
System.out.print(i.next()+" ");
}
System.out.println();

}
}

#    
## Explanation

* *Line 1*: We import the required package.
* *Line 2*: We make a `Main` class.
* *Line 4*: We make a `main` function.
* *Line 6*: We declare a deque that consists of `Integer` type elements.
* *Lines 8 to 14*: We use the `Deque.add()` method to insert the elements in the deque.
* *Line 16*: We declare an iterator for deque.
* *Lines 18 to 21*: We use a `while` loop to check the presence of the next element in the deque with the `Iterator.hasNext()` method. We then display the value of the iterator over each element.



What is the Deque.iterator() method in Java?

Deque.iterator() in Java provides an iterator over deque elements in their sequence, without parameters.
