In this shot, we will discuss the `Deque.size()` method in Java, which is present in the `Deque` interface inside the `java.util` package.

The **`Deque.size()` method** is used to obtain the number of elements present in the deque.

## Syntax
```
x size() 
```

## Parameter
The `Deque.size()` method doesn’t take any parameters.

## Return

The `Deque.size()` method returns **`size`**, which is the number of elements present in the `Deque`.

## Code
Let's look at the code snippet below.


import java.util.*;
class Main 
{
public static void main(String[] args)
{
Deque<Integer> d = new LinkedList<Integer>();
//Adding elements
d.add(212);
d.add(621);
d.add(23);
d.add(1280);
d.add(1171);

System.out.println("Elements in the deque are: "+d);
//Displaying the size of deque
System.out.println("Number of elements in the deque are: "+d.size());

}
}

## Explanation

* In line 1, we imported the required package.
* In line 2, we made a `Main` class.
* In line 4, we made a `main` function.
* In line 6, we declared a `Deque` consisting of `Integer` type elements.
* From line 8 to 12, we inserted values in the deque by using the `Deque.add()` method.
* In line 14, we displayed the original deque elements.
* In line 16, we used the `Deque.size()` method and displayed the number of elements present in the deque.

In this way, we can use the `Deque.size()` method in Java.


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

The Deque.size() method in Java retrieves the number of elements in the deque without any parameters.
