The 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.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val q 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
// Print the TreeSet
println(q 1 )
// Applying map method
val result = q 1 .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.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val q 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
// Print the TreeSet
println(q 1 )
// Applying map method
val result = q 1 .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)
