The init() method is utilized to return a new queue that consists of all the elements except the last one.
Method Definition: def init: Queue[A]
Return Type: It returns a new queue that consists of all the elements except the last one.
Example #1:
// Scala program of init() // 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 init method
val result = q 1 .init
// Display output
print( "Elements of the queue except the last one: " + result)
}
} |
Output:
Queue(1, 3, 2, 7, 6, 5) Elements of the queue except the last one: Queue(1, 3, 2, 7, 6)
Example #2:
// Scala program of init() // 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 init method
val result = q 1 .init
// Display output
print( "Elements of the queue except the last one: " + result)
}
} |
Output:
Queue(5, 3, 2, 7, 6, 1) Elements of the queue except the last one: Queue(5, 3, 2, 7, 6)
