Scala Stack init() method with example

Last Updated : 03 Nov, 2019

In Scala Stack class, the init() method is utilized to return a new stack that consists of all the elements except the last one.

Method Definition: def init: Stack[A]

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

Example #1:

// Scala program of init()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack(1, 3, 2, 7, 6, 5)  
          
        // Print the stack  
        println(s1)  
           
        // Applying init method   
        val result = s1.init  
          
        // Display output  
        print("Elements of the queue except the last one: " + result)  
         
    }  
}  

Output:

Stack(1, 3, 2, 7, 6, 5)
Elements of the queue except the last one: Stack(1, 3, 2, 7, 6)

Example #2:

// Scala program of init()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack(5, 3, 2, 7, 6, 1)  
          
        // Print the stack  
        println(s1)  
           
        // Applying init method   
        val result = s1.init  
          
        // Display output  
        print("Elements of the queue except the last one: " + result)  
         
    }  
}  

Output:

Stack(5, 3, 2, 7, 6, 1)
Elements of the queue except the last one: Stack(5, 3, 2, 7, 6)
