Last Updated : 03 Nov, 2019

In Scala Stack class, the mkString() method is utilized to display all elements of the stack in a string.

Method Definition: def mkString: String Return Type: It returns a string containing all the element of the stack.

Example #1:

Scala

// Scala program of mkString() 
// 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) 
        
        // Print the stack 
        println(s1) 
         
        // Applying mkString method  
        val result = s1.mkString
        
        // Display output 
        print("Stack: " + result) 
       
    } 
}

Output:

Stack(1, 2, 3, 4)
Stack: 1234

Example #2:

Scala

// Scala program of mkString() 
// method 

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

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating stack
        val s1 = Stack("Geeks", "for", "Geeks") 
        
        // Print the stack 
        println(s1) 
         
        // Applying mkString method  
        val result = s1.mkString
        
        // Display output 
        print("Stack: " + result) 
       
    }
