  • Last Updated : 03 Nov, 2019

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

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

Return Type: It returns a new stack that consists of all the elements except the last ‘n’ elements.

Example #1:




// Scala program of dropRight() 
// 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 dropRight method  
        val result = s1.dropRight(2
            
        // Displays output  
        print("Stack after dropRight(2) method: " + result)
    
Output:
Stack(6, 2, 3, 4, 5)
Stack after dropRight(2) method: Stack(6, 2, 3)

Example #2:




// Scala program of dropRight() 
// 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 dropRight method  
        val result = s1.dropRight(3
            
        // Displays output  
        print("Stack after dropRight(3) method: " + result)
