The map() method is utilized to build a new set by applying a function to all elements of this set.
Method Definition: def map[B](f: (A) => B): immutable.Set[B] Return Type: It returns a new set containing all the elements after applying the given function.
Example #1: Scala 
// Scala program of map() 
// method 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a set 
        val s1 = Set(5, 1, 3, 2, 4) 
        
        // Applying map method 
        val result = s1.map(x => x*x)
        
        // Display output
        println(result)
    } 
}
Output: 
Set(25, 1, 9, 16, 4)
Example #2: Scala 
// Scala program of map() 
// method

object GfG 
{ 

    // Main method 
    def main(args:Array[String])

        // Creating a set 
        val s1 = Set(5, 1, 3, 2, 4) 
        
        // Applying map method 
        val result = s1.map(x => x/2)
        
        // Display output
        println(result)
