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

// 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

// 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

// 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
