Scala immutable TreeSet map() method

  • Last Updated : 19 Apr, 2020

In Scala immutable TreeSet class map() method is utilized to build a new TreeSet by applying a function to all elements of the given TreeSet.

Method Definition: def map[B](f: (A) => B): TreeSet[B]

Return Type: It returns a new TreeSet containing all the elements after applying the given function.

Example #1:




// Scala program of map() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val q1 = TreeSet(1, 2, 3, 4, 5)  
            
        // Print the TreeSet 
        println(q1
          
        // Applying map method  
        val result = q1.map(x => x*x)  
            
        // Displays output  
        print("TreeSet with squared elements: " + result) 
          
    
Output:
TreeSet(1, 2, 3, 4, 5)
TreeSet with squared elements: TreeSet(1, 4, 9, 16, 25)

Example #2:




// Scala program of map() 
// method 
  
// Import TreeSet
import scala.collection.immutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val q1 = TreeSet(1, 2, 3, 4, 5)  
            
        // Print the TreeSet 
        println(q1
          
        // Applying map method  
        val result = q1.map(x => x*x*x)  
            
        // Displays output  
        print("TreeSet with cubed elements: " + result) 
          
    
Output:
TreeSet(1, 2, 3, 4, 5)
TreeSet with cubed elements: TreeSet(1, 8, 27, 64, 125)
