Scala Stack tail() method with example

In Scala Stack class, the tail() method is utilized to return a new stack that consists of all the elements except the first one.

Method Definition: def tail: Stack[A]

Return Type: It returns a new stack that consists of all the elements except the first one.

Example #1:

// Scala program of tail()
// method

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

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(1, 3, 2, 7, 6, 5)

        // Print the stack
        println(s1)

        // Applying tail method
        val result = s1.tail

        // Display output
        print("Elements of the queue except the first one: " + result)

    }
}

Output:

Stack(1, 3, 2, 7, 6, 5)
Elements of the queue except the first one: Stack(3, 2, 7, 6, 5)

Example #2:

// Scala program of tail()
// method

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

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(5, 3, 2, 7, 6, 1)

        // Print the stack
        println(s1)

        // Applying tail method
        val result = s1.tail

        // Display output
        print("Elements of the queue except the first one: " + result)

    }
}

Output:

Stack(5, 3, 2, 7, 6, 1)
Elements of the queue except the first one: Stack(3, 2, 7, 6, 1)
