How to get the first element of List in Scala

  • Last Updated : 17 Apr, 2019

In Scala, list is defined under scala.collection.immutable package. A list is a collection of same type elements which contains immutable data. Let’s see how to get the first element of given List in Scala.

List in Scala contains many suitable methods to perform simple operations like head(), tail(), isEmpty(). Coming to list, head() method is used to get the heead/top element of the list.
below are examples to get first element of list.

Example :




// Scala program to print immutable lists 
import scala.collection.immutable._
  
// Creating object 
object GFG
    // Main method 
    def main(args:Array[String]) 
    
        // Creating and initializing immutable lists 
        val mylist: List[String] = List("Geeks", "For", "geeks", "is",
                                        "a", "fabulous", "portal")
  
        println("The head of the list is:"
        println(mylist.head) 
    }
}

Output:

The head of the list is:
Geeks

Example :




// Scala program to creating a uniform list 
import scala.collection.immutable._
  
// Creating object 
object GFG 
    // Main method 
    def main(args:Array[String]) 
    
        // Repeats Scala three times. 
        val myList = List.range(10, 19)
        println(myList) 
  
        println("First element is: " + myList.head)
    

Output:

List(10, 11, 12, 13, 14, 15, 16, 17, 18)
First element is: 10
