The dropRight() method is utilized to drop the last ‘n’ elements of the queue.
Method Definition: def dropRight(n: Int): Queue[A]
Return Type: It returns a new queue that consists of all the elements except the last ‘n’ elements.
Example #1:
// Scala program of dropRight() // method // Import Queue import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating queues
val q 1 = Queue( 1 , 2 , 3 , 4 , 5 )
// Print the queue
println(q 1 )
// Applying dropRight method
val result = q 1 .dropRight( 2 )
// Displays output
print( "Queue after dropRight(2) method: " + result)
}
} |
Output:
Queue(1, 2, 3, 4, 5) Queue after dropRight(2) method: Queue(1, 2, 3)
Example #2:
// Scala program of dropRight() // method // Import Queue import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating queues
val q 1 = Queue( 1 , 2 , 3 , 4 , 5 )
// Print the queue
println(q 1 )
// Applying dropRight method
val result = q 1 .dropRight( 3 )
// Displays output
print( "Queue after dropRight(3) method: " + result)
}
} |
Output:
Queue(1, 2, 3, 4, 5) Queue after dropRight(3) method: Queue(1, 2)
