#  What is `LinkedList`?
A **linked list** is a collection of linear data elements. Each element (node) contains data and reference parts. The **data part** has the value and the **reference part** has the address to the next element. 

The elements are not indexed so random access is not possible. Instead, we traverse from the beginning of the list and access the elements.

> In Java, the **`LinkedList`** is a #key# doubly-linked list: Kind of linked list. Each node contains three fields: two link fields(one for the previous element and another for the next element) and one data field.  #key# implementation of the List and Deque interfaces.  The `LinkedList` is class present in the `java.util` package.

#   
#  What is the `size` method of the `LinkedList` class?

The **`size`** method can be used to get the #key# size: Number of elements present in the list #key# of the linked list.

##  
## Syntax 

```java
public int size()
```

This method doesn't take in any arguments. It returns the number of elements present in the list as an integer.

##  
## Code 

The code below demonstrates how to use the `size` method.





import java.util.LinkedList;
class LinkedListSize {
    public static void main( String args[] ) {
      LinkedList<String> list = new LinkedList<>();
      list.add("1");
      list.add("2");
      list.add("3");
      System.out.println("The list is " + list);

      System.out.println("The size of list is : " + list.size());
    }
}

#   
## Explanation 

In the code above:

* In line 1, we imported the `LinkedList` class.
```java
import java.util.LinkedList;
```

* In line 4, we created a `LinkedList` object with the name `list`. 

```java
LinkedList<String> list = new LinkedList<>();
```
* In lines 5 to 7, we used the `add` method of the list object to add three elements (`"1","2","3"`) to the list.

```java
list.add("1");
list.add("2");
list.add("3");
```

* In line 10, we used the `size` method of the list object to get the size of the list. In our case, `3` will be returned because the `list` object has `3` elements.

```java
list.size(); // 3
```
