How to reverse 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. We use reverse function to reverse a list in Scala.
Below are the examples to reverse a list.

• Reverse a simple list

  // Scala program to reverse 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", "is", "best")
  
          // Display the value of mylist1
          println("Reversed List is: " + mylist.reverse)
  
      }
  }

  Output:

  
  
  

  Reversed List is: List(best, is, geeks, For, Geeks)

• Reverse a list using for loop

  // Scala program to print reverse immutable lists
  // using for loop
  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 in
          // reverse order using for loop
          for(element<-mylist.reverse)
          {
              println(element)
          }
      }
  }

  Output:

  
  
  

  portal
  fabulous
  a
  is
  geeks
  For
  Geeks

• Reverse a list using foreach loop

  // Scala program to reverse a list
  // using foreach loop
  import scala.collection.immutable._
  
  // Creating object
  object GFG
  {
      // Main method
      def main(args:Array[String])
      {
          // Creating and initializing immutable lists
          val mylist = List("Geeks", "For", "geeks", "is",
                          "a", "fabulous", "portal")
  
          print("Original list is: ")
  
          // Display the value of mylist using for loop
          mylist.foreach{x:String => print(x + " ") }
  
          // calling reverse function
          println("\nReversed list: " + mylist.reverse)
      }
  }

  Output:

  Original list is: Geeks For geeks is a fabulous portal 
  Reversed list: List(portal, fabulous, a, is, geeks, For, Geeks)
