Scala Stack pop() method with example

Last Updated : 03 Nov, 2019

In Scala Stack class, the pop() method is utilized to remove and return the element at the top of the stack.

Method Definition: def pop(): A Return Type: It removes and returns the element at the top of the stack.

Example #1:

Scala

// Scala program of pop() 
// method 

import scala.collection.mutable.Stack 

// Creating object 
object GfG 
{ 
    
    // Main method 
    def main(args:Array[String]) 
    { 
        
        // Creating a stack
        var s = Stack("C++", "Java", "Python", "Scala") 
        
        // Print the stack
        println(s)
        
        // Print the top of the stack
        println("Top of the stack: " + s.top)

        // Applying pop method    
        val result = s.pop
        
        // Print the popped element
        println("Popped element: " + result) 

    } 
}

Output:

Stack(C++, Java, Python, Scala)
Top of the stack: C++
Popped element: C++

Example #2:

Scala

// Scala program of pop() 
// method 

import scala.collection.mutable.Stack 

// Creating object 
object GfG 
{ 
    
    // Main method 
    def main(args:Array[String]) 
    { 
        
        // Creating a stack
        var s = Stack(1, 2, 3, 4) 
        
        // Print the stack
        println(s)
        
        // Print the top of the stack
        println("Top of the stack: " + s.top)

        // Applying pop method    
        val result = s.pop
        
        // Print the popped element
        println("Popped element: " + result) 

    } 
}

Output:

Stack(1, 2, 3, 4)
Top of the stack: 1
Popped element: 1
