The drop() method belongs to the concrete value member of the class Abstract Iterator. It is defined in the classes Iterator and IterableOnceOps. It is utilized to move the iterator n places ahead and if n is greater than the iterator’s length, then it will throw an exception.
Method Definition : def drop(n: Int): Iterator[A]
Where, n is the number of elements to be dropped from the stated iterator.
Return Type : It returns all the elements of the stated iterator except the first n ones.
Example #1:
// Scala program of drop()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating an Iterator val iter = Iterator(4, 6, 10, 11, 13) // Applying drop method val x = iter.drop(4) // Applying next method val result = x.next() // Displays output println(result) }} |
13
Here, the first four elements are dropped and all the elements after that are returned.
Example #2:
// Scala program of drop()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating an Iterator val iter = Iterator(2, 3, 4) // Applying drop method val x = iter.drop(1) // Applying next method val result = x.next() // Displays output println(result) }} |
