Scala Stack drop() method with example

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

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

Return Type: It returns a new stack with all the elements except the first ‘n’ ones from the top of the given stack.

Example #1:

// Scala program of drop()
// 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 drop method
        val result = s1.drop(2)

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

Output:

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

Example #2:

// Scala program of drop()
// 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 drop method
        val result = s1.drop(3)

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

Output:

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