Scala Mutable SortedMap dropRight() method with example
The dropRight() method is utilized to delete the last ‘n’ elements.
Method Definition: def dropRight(n: Int): SortedMap[A, B]
Return Type: It returns all the elements of the SortedMap except the last ‘n’ elements.
Example #1:
// Scala program of dropRight() // method import scala.collection.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedMap val m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 , "cs" - > 5 ) // Applying dropRight method val result = m 1 .dropRight( 1 ) // Displays output println(result) } } |
Output:
Map(cs -> 5, for -> 3)
Example #2:
// Scala program of dropRight() // method import scala.collection.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedMap val m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 ) // Applying dropRight method val result = m 1 .dropRight( 2 ) // Displays output println(result) } } |
Output:
Map()
So, here an empty SortedMap is returned as all the elements of the SortedMap are deleted.
