IntStream

Lab Java Intermediate 20 points

Read n. Using IntStream.rangeClosed, print the sum of 1..n, the sum of squares of the odd numbers, and whether any number in range is divisible by 97 (anyMatch).

Input

Hints

IntStream.rangeClosed(1, n) produces 1..n.

asLongStream() avoids int overflow when summing.

Solution explanation

Primitive streams (IntStream, LongStream) avoid boxing and add sum, average, max.

import java.util.Scanner;
import java.util.stream.IntStream;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        System.out.println(IntStream.rangeClosed(1, n).asLongStream().sum());
        System.out.println(IntStream.rangeClosed(1, n).filter(x -> x % 2 == 1).asLongStream().map(x -> x * x).sum());
        System.out.println(IntStream.rangeClosed(1, n).anyMatch(x -> x % 97 == 0));
    }
}
