Scala Stack distinct() method with example

Last Updated : 03 Nov, 2019

In Scala Stack class, the distinct() method is utilized to delete the duplicate elements from the given stack.

Method Definition: def distinct: Stack[A]

Return Type: It returns a new stack with only distinct elements.

Example #1:

// Scala program of distinct()  
// 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, 1, 2, 1, 3, 2, 3, 3)  
          
        // Print the stack 
        println(s1)  
          
        // Applying distinct() method   
        val result = s1.distinct 
          
        // Display output  
        print("Stack with distinct elements: " + result)  
           
    }  
}  

Output:

Stack(1, 3, 2, 1, 2, 1, 3, 2, 3, 3)
Stack with distinct elements: Stack(1, 3, 2)

Example #2:

// Scala program of distinct()  
// method  
  
// Import Stack  
import scala.collection.mutable._
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating stack 
        val s1 = Stack("g", "e", "e", "k", "s", "f", "o", "r", "g", "e", "e", "k", "s")  
          
        // Print the stack 
        println(s1)  
          
        // Applying distinct() method   
        val result = s1.distinct 
          
        // Display output  
        print("Stack with distinct elements: " + result)  
           
    }  
}  

Output:

Stack(g, e, e, k, s, f, o, r, g, e, e, k, s)
Stack with distinct elements: Stack(g, e, k, s, f, o, r)
