Scala Mutable Set Example:

import scala.collection.mutable.Set

object MutableSetExample extends App {
// Create a mutable set
val movies = Set("OG", "Salaar")

// Add elements
movies += "Rajasaab"
movies.add("Peddi")

// Remove elements
movies -= "OG"
movies.remove("Salaar")

// Print the set
println(movies)
}


Output:
Set(Rajasaab, Peddi)




Scala Immutable Set Example:

object ImmutableSetExample extends App {
// Create an immutable set
val movies = Set("OG", "Peddi")

// Adding an element returns a new set
val newMovies = movies + "Rajasaab"

// Removing an element returns a new set
val fewerMovies = newMovies - "Peddi"

// Original set remains unchanged
println("Original Set: " + movies)
println("After Adding: " + newMovies)
println("After Removing: " + fewerMovies)
}

Output:

Original Set: Set(OG, Peddi)
After Adding: Set(OG, Peddi, Rajasaab)
After Removing: Set(OG, Rajasaab)
