  • 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

        val s1 = Stack(5, 3, 2, 7, 6, 1
          
        // Print the stack 
        println(s1
           
        // Applying init method  
        val result = s1.init
