The **`list.tail` function** in Scala returns the reference of all the elements in the list except the first element. 

Figure 1 shows a visual representation of the `list.tail` function.

#      
## Syntax

```scala
list_name.tail
// where the list_name is the name of the list
```
## Parameters

This function does not require any parameters.

## Return value
The `list.tail` function returns the reference of all the elements in the list except the first element.

- It does not remove that element from the list.
- If the list is empty, then it throws an `error`.

## Code
The following code shows how to use the `list.tail` function in Scala.


object Main extends App {
  var list = List(1,3,4,2,0)
    
  //list = 1->3->4->2->0
  println("Following are the elements in List before using list.tail: " + list);
  println("The elements on the tail of list: "+list.tail);
  println("Following are the elements in list after using list.tail: " + list);
}

What is the list.tail method in Scala?

Returns reference to all elements in a list except the first; empty list throws an error.
