Method Definition: def tail: Queue[A]
Return Type: It return a new queue that consists of all the elements except the first one.
Example #1:
// Scala program of tail() // 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 , 3 , 2 , 7 , 6 , 5 )
// Print the queue
println(q 1 )
// Applying tail method
val result = q 1 .tail
// Display output
print( "Tail of the queue: " + result)
}
} |
Output:
Queue(1, 3, 2, 7, 6, 5) Tail of the queue: Queue(3, 2, 7, 6, 5)
Example #2:
// Scala program of tail() // method // Import Queue import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating queues
val q 1 = Queue( 5 , 3 , 2 , 7 , 6 , 1 )
// Print the queue
println(q 1 )
// Applying tail method
val result = q 1 .tail
// Display output
print( "Tail of the queue: " + result)
}
} |
Output:
Queue(5, 3, 2, 7, 6, 1) Tail of the queue: Queue(3, 2, 7, 6, 1)
