Return Type: It returns a stack consisting of the first ‘n’ elements of the stack.

Example #1:




// Scala program of take() 
// 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 take method  
        val result = s1.take(2)
          
        // Display output 
        print("Stack containing first two elements: " + result) 
         
    
Output:
Stack(1, 2, 3, 4)
Stack containing first two elements: Stack(1, 2)

Example #2:




// Scala program of take() 
// method

// Creating object 
object GfG

        println(s1
           
        // Applying take method  
        val result = s1.take(3)
          
        // Display output 
        print("Stack containing first three elements: " + result)
