Scala Stack reverse() method with example

In Scala Stack class, the reverse() method is utilized to return a stack with the reverse order.

Method Definition: def reverse: Stack[A]

Return Type: It returns a stack with the reverse order.

Example #1:

// Scala program of reverse()
// 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, 5, 6)

        // Print the stack
        println(s1)

        // Applying reverse method
        val result = s1.reverse

        // Display output
        print("Reversed stack: " + result)

    }
}

Output:

Stack(1, 2, 3, 4, 5, 6)
Reversed stack: Stack(6, 5, 4, 3, 2, 1)

Example #2:

// Scala program of reverse()
// method

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

// Creating object
object GfG
{

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

        // Creating stack
        val s1 = Stack(5, 2, 13, 7, 1, 3)

        // Print the stack
        println(s1)

        // Applying reverse method
        val result = s1.reverse

        // Display output
        print("Reversed stack: " + result)

    }
}

Output:

Stack(5, 2, 13, 7, 1, 3)
Reversed stack: Stack(3, 1, 7, 13, 2, 5)
