Find the last element of 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 generally use last function to print last element of a list.

Below are the examples to find the last element of a given list in Scala.

• Simply print last element of a list

  // Scala program to find the last element of a given list
  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 last value of mylist
          println("Last element is: " + mylist.last)
  
      }
  }

  Output:

  Last element is: best

  
  
  
• Print last element of a list using for loop

  // Scala program to find the last element of a given list
  // 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 last value of mylist using for loop
          for(element<-mylist.last)
          {
              print(element)
          }
      }
  }

  Output:

  portal

• Print last element of a list using foreach loop

  // Scala program to find the last element of a given 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(1, 2, 3, 4, 5, 6)
  
  
          print("Original list is: ")
          // Display the value of mylist using for loop
          mylist.foreach{x:Int => print(x + " ") }
  
          // calling last function
          println("\nLast element is: " + mylist.last)
      }
  }

  Output:

  Original list is: 1 2 3 4 5 6 
  Last element is: 6
