  • Last Updated : 03 Nov, 2019

In Scala Stack class, the drop() method is utilized to drop the first ‘n’ elements from the top of the stack.

Method Definition: def drop(n: Int): Stack[A]

Return Type: It returns a new stack with all the elements except the first ‘n’ ones from the top of the given stack.

Example #1:




// Scala program of drop() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating stack  
        val s1 = Stack(6, 2, 3, 4, 5)  
            
        // Print the stack 
        println(s1)  
          
        // Applying drop method  
        val result = s1.drop(2
            
        // Displays output  
        print("Stack after drop(2) method: " + result)
    
Output:
Stack(6, 2, 3, 4, 5)
Stack after drop(2) method: Stack(3, 4, 5)

Example #2:




// Scala program of drop() 
// method 
  
// Import Stack 
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating stack  
        val s1 = Stack(6, 2, 3, 4, 5)  
            
        // Print the stack 
        println(s1)  
          
        // Applying drop method  
        val result = s1.drop(3
            
        // Displays output  
        print("Stack after drop(3) method: " + result)
