Question 1

+4 marksOne correct option

Method Stream.iterate(e, f) returns an infinite sequential ordered Stream produced by iterative application of a function f to an initial element e, producing a Stream consisting of e, f(e), f(f(e)), etc. Based on the above information, consider the code given below, and answer the question that follows.

java

1import java.util.stream.*;
2public class Test {
3    public static void main(String[] args) {
4        Stream.iterate(8, n -> n-1)
5                .map(n -> n + 2)
6                .filter(n -> n % 3 == 0)
7                .limit(4)
8                .forEach((x) -> System.out.print(x + " "));
9  }
