Scala Stack takeRight() method with example

In Scala Stack class, the takeRight() method is utilized to return a stack consisting of the last ‘n’ elements of the stack.

Method Definition: def takeRight(n: Int):Stack[A]

Return Type: It returns a stack consisting of the last ‘n’ elements of the stack.

Example #1:

// Scala program of takeRight()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(1, 2, 3, 4)

        // Print the stack
        println(s1)

        // Applying takeRight method
        val result = s1.takeRight(2)

        // Display output
        print("Stack containing last two elements: " + result)

    }
}

Output:

Stack(1, 2, 3, 4)
Stack containing last two elements: Stack(3, 4)

Example #2:

// Scala program of takeRight()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(1, 2, 3, 4)

        // Print the stack
        println(s1)

        // Applying takeRight method
        val result = s1.takeRight(3)

        // Display output
        print("Stack containing last three elements: " + result)

    }
}

Output:

Stack(1, 2, 3, 4)
Stack containing last three elements: Stack(2, 3, 4)
