Scala Stack distinct() method with example

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

// 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

// 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)
