Oracle Exam 1Z0-809 Topic 19 Question 6 Discussion

Given:

public class Product {

int id; int price;

public Product (int id, int price) {

this.id = id;

this.price = price;

}

Public String toString () { return id + '':'' + price;)

}

and the code fragment:

List products = new ArrayList <> (Arrays.asList(new Product(1, 10),

new Product (2, 30),

new Product (3, 20));

Product p = products.stream().reduce(new Product (4, 0), (p1, p2) -> {

p1.price+=p2.price;

return new Product (p1.id, p1.price);});

products.add(p);

products.stream().parallel()

.reduce((p1, p2) - > p1.price > p2.price ? p1 : p2)

.ifPresent(System.out: :println);

What is the result?
