public Product (int id, int price) {
this.id = id;
this.price = price;
}
Public String toString () { return id + ":" + price;)
}
and the code fragment:
List<Product> 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?
