In Scala mutable collections, map() method is utilized to build a new SortedSet by applying a function to all elements of this SortedSet.
Method Definition: def map[B](f: (A) => B): mutable.SortedSet[B]
Return Type: It returns a new SortedSet containing all the elements after applying the given function.
Example #1:
// Scala program of map() // method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 5 , 1 , 3 , 2 , 4 )
// Applying map method
val result = s 1 .map(x => x*x)
// Display output
println(result)
}
} |
Output:
TreeSet(1, 4, 9, 16, 25)
Example #2:
// Scala program of map() // method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 5 , 12 , 3 , 2 , 4 )
// Applying map method
val result = s 1 .map(x => x/ 2 )
// Display output
println(result)
}
} |
Output:
TreeSet(1, 2, 6)
