Scala Stack drop() method with example

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) 
    }  
}  

Output:

Stack(6, 2, 3, 4, 5)
Stack after drop(3) method: Stack(4, 5)
