Last Updated :

The dropRight() method is utilized to delete the last ‘n’ elements.
Method Definition: def dropRight(n: Int): Map[A, B]
Return Type: It returns all the elements of the map except the last ‘n’ elements.
Example #1:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "cs" - > 5 )
val result = m 1 .dropRight( 1 )
println(result)
}
}
|
Output:
Map(geeks -> 5, for -> 3)
Example #2:
object GfG
{
def main(args : Array[String])
{
val m 1 = Map( "geeks" - > 5 , "for" - > 3 )
val result = m 1 .dropRight( 2 )
println(result)
}
}
|
So, here an empty map is returned as all the elements of the map are deleted.
