How to print a list in Scala

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 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 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 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
