Scala Stack push() method with example

Last Updated : 03 Nov, 2019

In Scala Stack class, the push() method is utilized to add an element on the top of the stack.

Method Definition: def push(elem: A): Stack.this.type Return Type: It adds an element on the top of the stack.

Example #1:

Scala

// Scala program of push() 
// method 

import scala.collection.mutable.Stack 

// Creating object 
object GfG 
{ 
    
    // Main method 
    def main(args:Array[String]) 
    { 
        
        // Creating a stack
        var s = Stack[Int]() 

        // Applying push method
        s.push(1)
        s.push(2) 
        s.push(3) 
        s.push(4)
        
        // Print the Stack
        println(s) 

    } 
}

Output:

Stack(4, 3, 2, 1)

Example #2:

Scala

// Scala program of push() 
// method 

import scala.collection.mutable.Stack 

// Creating object 
object GfG 
{ 
    
    // Main method 
    def main(args:Array[String]) 
    { 
        
        // Creating a stack
        var s = Stack[String]() 

        // Applying push method
        s.push("C++")
        s.push("Java") 
        s.push("Python") 
        s.push("Scala")
        
        // Print the Stack
        println(s) 

    } 
}

Output:

Stack(Scala, Python, Java, C++)
