In Scala Stack class, the dropWhile() method is utilized to drop the longest prefix from the top which satisfies a given predicate in a stack.
Method Definition: def dropWhile(p: (A) => Boolean): Stack[A]
Return Type: It returns a new stack that consists of elements after dropping the longest prefix satisfying the given predicate.
Example #1:
// Scala program of dropWhile() // 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 dropWhile method val result = s1.dropWhile(x => {x % 2 == 0}) // Displays output print("Stack after using dropWhile() method: " + result) } } |

Output:
Stack(6, 2, 3, 4, 5) Stack after using dropWhile() method: Stack(3, 4, 5)
Example #2:
// Scala program of dropWhile() // method // Import Stack import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating stack val s1 = Stack(1, 7, 2, 3, 4, 5) // Print the stack println(s1) // Applying dropWhile method val result = s1.dropWhile(x => {x % 2 != 0}) // Displays output print("Stack after using dropWhile() method: " + result) } } |
