In Scala Stack class
, the take() method is utilized to return a stack consisting of the first ‘n’ elements of the stack.
Method Definition: def take(n: Int): Stack[A]
Return Type: It returns a stack consisting of the first ‘n’ elements of the stack.
Example #1:
// Scala program of take() // 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 , 2 , 3 , 4 )
// Print the stack
println(s 1 )
// Applying take method
val result = s 1 .take( 2 )
// Display output
print( "Stack containing first two elements: " + result)
}
} |
Output:
Stack(1, 2, 3, 4) Stack containing first two elements: Stack(1, 2)
Example #2:
// Scala program of take() // 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 , 2 , 3 , 4 )
// Print the stack
println(s 1 )
// Applying take method
val result = s 1 .take( 3 )
// Display output
print( "Stack containing first three elements: " + result)
}
} |
Output:
Stack(1, 2, 3, 4) Stack containing first three elements: Stack(1, 2, 3)
