Scala Stack reverse() method with example

Last Updated : 03 Nov, 2019

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

// 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

// 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)
