The `toString()` method will return the string representation of the `LinkedList` object with the string representation of each element in the list.


> In Java, a `LinkedList` is a doubly-linked list implementation of the `List` and `Deque` interfaces.  The `LinkedList` class is present in the `java.util` package. Read more about the `LinkedList` [here](https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html).
# Syntax

```java
public String toString()
```
# Parameters
This method doesn't take any arguments. 

# Return value
This method returns a string. This string contains the elements of the list in the insertion order enclosed between `[]` and separated by a comma. Internally, the elements are converted to string using the `String.valueOf(Object)` method.

# Code
The code below demonstrates how the `toString()` method can be used.

import java.util.LinkedList;
class LinkedListAdd {
    public static void main( String args[] ) {
      LinkedList<Integer> list = new LinkedList<>();
      list.add(1);
      list.add(2);
      list.add(3);
      System.out.println(list.toString());
    }
}

## Explanation
* In *line 1*: We imported the `LinkedList` class.

* In *line 4*: We created a new `LinkedList` object with the name `list`.

* From *lines 5-7*: We added three elements (`1`,`2`,`3`) to `list` using the `add()` method.

* In *line 8*: We used the `toString()` method to get the string representation of `list`.

What is the LinkedList.toString method in Java?

The toString() method returns a string with elements of a LinkedList in insertion order, enclosed in brackets.
