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