Scala Stack drop() method with example
In Scala Stack class, the drop() method is utilized to drop the first ‘n’ elements from the top of the stack.
Method Definition: def drop(n: Int): Stack[A]
Return Type: It returns a new stack with all the elements except the first ‘n’ ones from the top of the given stack.
Example #1:
// Scala program of drop() // method // Import Stack import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating stack val s1 = Stack(6, 2, 3, 4, 5) // Print the stack println(s1) // Applying drop method val result = s1.drop(2) // Displays output print("Stack after drop(2) method: " + result) } } |
Output:
Stack(6, 2, 3, 4, 5) Stack after drop(2) method: Stack(3, 4, 5)
Example #2:
// Scala program of drop() // method // Import Stack import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating stack val s1 = Stack(6, 2, 3, 4, 5) // Print the stack println(s1) // Applying drop method val result = s1.drop(3) // Displays output print("Stack after drop(3) method: " + result) } } |
Output:
Stack(6, 2, 3, 4, 5) Stack after drop(3) method: Stack(4, 5)
