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:
// Scala program of dropRight() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a map
val m 1 = Map( "geeks" - > 5 , "for" - > 3 , "cs" - > 5 )
// Applying dropRight method
val result = m 1 .dropRight( 1 )
// Displays output
println(result)
}
} |
Output:
Map(geeks -> 5, for -> 3)
Example #2:
// Scala program of dropRight() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a map
val m 1 = Map( "geeks" - > 5 , "for" - > 3 )
// Applying dropRight method
val result = m 1 .dropRight( 2 )
// Displays output
println(result)
}
} |
Output:
Map()
So, here an empty map is returned as all the elements of the map are deleted.
