How to print a list in Scala

Last Updated : 11 Jul, 2025

In Scala, list is defined under scala.collection.immutable package. A list is a collection of same type elements which contains immutable data. There are multiple ways to create a List in Scala. Let's see few basic on how to create a Scala List.

Create an empty List Example :

scala

// Scala program to create an empty list 
import scala.collection.immutable._

// Creating object 
object GFG
{ 
    // Main method 
    def main(args:Array[String]) 
    { 

        // Creating an Empty List. 
        val emptylist: List[Nothing] = List() 
        println("The empty list is: " + emptylist) 
    } 
}

Output:

The empty list is: List()

Create a simple list Example :

scala

// Scala program to create a simple 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") 
    

        // Display the value of mylist1 
        println("List is: " + mylist) 
    

    } 
}

Output:

List is: List(Geeks, For, geeks)

Using for loop to print elements of List Example :

scala

// 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")

        // Display the value of mylist using for loop 
        for(element<-mylist) 
        { 
            println(element) 
        } 
    } 
}

Output:

Geeks
For
geeks
is
a
fabulous
portal
