In Scala TreeSet class
, the dropRight() method is utilized to drop the last ‘n’ elements of the TreeSet.
Method Definition: def dropRight(n: Int): TreeSet[A]
Return Type: It returns a new TreeSet that consists of all the elements except the last ‘n’ elements.
Example #1:
// Scala program of dropRight() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 2 , 4 , 6 , 7 , 8 , 9 )
// Print the TreeSet
println(t 1 )
// Applying dropRight() method
val result = t 1 .dropRight( 2 )
// Displays output
println( "Queue after using dropRight(2) method: " + result)
}
} |
Output:
TreeSet(2, 4, 6, 7, 8, 9) Queue after using dropRight(2) method: TreeSet(2, 4, 6, 7)
Example #2:
// Scala program of dropRight() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 2 , 4 , 6 , 7 , 8 , 9 )
// Print the TreeSet
println(t 1 )
// Applying dropRight() method
val result = t 1 .dropRight( 4 )
// Displays output
println( "Queue after using dropRight(4) method: " + result)
}
} |
Output:
TreeSet(2, 4, 6, 7, 8, 9) Queue after using dropRight(4) method: TreeSet(2, 4)
