Assume customers.txt is accessible and contains multiple lines.

Which code fragment prints the contents of the customers.txt file?

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

new Product (2, 30),

new Product (2, 30));

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?

Given the content of the employee.txt file:

Every worker is a master.

Given that the employee.txt file is accessible and the file allemp.txt does NOT exist, and the code fragment:

What is the result?

What is true about the java.sql.Statement interface?

Given the code fragment:

Stream < List < String > > iStr= Stream.of (

Arrays.asList (“1”, “John”),

Arrays.asList (“2”, null)0;

Stream < < String > nInSt = iStr.flatMapToInt ((x) - > x.stream ());

nInSt.forEach (System.out :: print);

What is the result?

Given the code fragment:

List < Integer > codes = Arrays.asList (10, 20);

UnaryOperator < Double > uo = s - > s +10.0;

codes.replaceAll(uo);

codes.forEach(c - > System.out.println(c));

Given the code fragment:

ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 1, 0, 0, 0, ZoneID.of(“UTC-7”));

ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of(“UTC-5”));

long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1

System.out.println(“Travel time is” + hrs + “hours”);

What is the result?

Given the code fragment:

BiFunction < Integer, Double, Integer > val = (t1, t2) - > t1 + t2;//line n1

System.out.println(val.apply(10, 10.5));

What is the result?
