object GfG
{
def main(args : Array[String])
{

println(t 1 )
val result = t 1 .dropRight( 2 )
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:
import scala.collection.mutable. _
object GfG
{
def main(args : Array[String])
{
val t 1 = TreeSet( 2 , 4 , 6 , 7 , 8 , 9 )
println(t 1 )
val result = t 1 .dropRight( 4 )
println( "Queue after using dropRight(4) method: " + result)
}
}
