Given the code fragment:
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with the dbURL, userName, and passWord exists
The Employee table has a column ID of type integer and the SQL query matches one record.
What is the result?
Given:
public class Emp {
String fName;
String lName;
public Emp (String fn, String ln) {
fName = fn;
lName = ln;
}
public String getfName() { return fName; }
public String getlName() { return lName; }
}
and the code fragment:
List
new Emp (“John”, “Smith”),
new Emp (“Peter”, “Sam”),
new Emp (“Thomas”, “Wale”));
emp.stream()
//line n1
.collect(Collectors.toList());
Which code fragment, when inserted at line n1, sorts the employees list in descending order of fName and then ascending order of lName?
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
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?
Given the code fragment:
BiFunction
//line n2
System.out.println(val.apply(10, 10.5));
What is the result?
Given the code fragment:
ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 3, 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?

int с = a / b;
System.out.println (c);
}
}
