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)
