Scala Stack dropRight() method with example

In Scala Stack class, the dropRight() method is utilized to drop the last ‘n’ elements of the stack.

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

Return Type: It returns a new stack that consists of all the elements except the last ‘n’ elements.

Example #1:

// Scala program of dropRight()
// method

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

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(6, 2, 3, 4, 5)

        // Print the stack
        println(s1)

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

        // Displays output
        print("Stack after dropRight(2) method: " + result)
    }
}

Output:

Stack(6, 2, 3, 4, 5)
Stack after dropRight(2) method: Stack(6, 2, 3)

Example #2:

// Scala program of dropRight()
// method

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

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(6, 2, 3, 4, 5)

        // Print the stack
        println(s1)

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

        // Displays output
        print("Stack after dropRight(3) method: " + result)
    }
}

Output:

Stack(6, 2, 3, 4, 5)
Stack after dropRight(3) method: Stack(6, 2)
