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:
import scala.collection.immutable. _
object GfG
{
def main(args : Array[String])
{
val q 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
println(q 1 )
val result = q 1 .map(x => x*x)
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:
import scala.collection.immutable. _
object GfG
{
def main(args : Array[String])
{
val q 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
println(q 1 )
val result = q 1 .map(x => x*x*x)
print( "TreeSet with cubed elements: " + result)
}
}

Output:
TreeSet(1, 2, 3, 4, 5)
TreeSet with cubed elements: TreeSet(1, 8, 27, 64, 125)
