Given:

and the code fragment:

Which two code fragments, when inserted at line n1 independently, enable the code to print TruckCarBike?

• A..sorted ((v1, v2) -> v1.getVId() < v2.getVId())
• B..sorted (Comparable.comparing (Vehicle: :getVName)).reversed ()
• C..map (v -> v.getVid()).sorted ()
• D..sorted((v1, v2) -> Integer.compare(v1.getVId(), v2.getVid()))
• E..sorted(Comparator.comparing ((Vehicle v) -> v.getVId()))

Given:
class UserException extends Exception { }
class AgeOutOfLimitException extends UserException { }
and the code fragment:
class App {
public void doRegister(String name, int age)
throws UserException, AgeOutOfLimitException {
if (name.length () < 6) {
throw new UserException ();
} else if (age >= 60) {
throw new AgeOutOfLimitException ();
} else {
System.out.println("User is registered.");
}
}
public static void main(String[ ] args) throws UserException {
App t = new App ();
t.doRegister("Mathew", 60);
}
}
What is the result?

• A.A compilation error occurs in the main method.
• B.User is registered.
• C.A UserException is thrown.
• D.An AgeOutOfLimitException is thrown.

Given the code fragment:
9. Connection conn = DriveManager.getConnection(dbURL, userName, passWord);
10. String query = "SELECT id FROM Employee";
11. try (Statement stmt = conn.createStatement()) {
12. ResultSet rs = stmt.executeQuery(query);
13.stmt.executeQuery("SELECT id FROM Customer");
14. while (rs.next()) {
15. //process the results
16.System.out.println("Employee ID: "+ rs.getInt("id"));
17.}
18. } catch (Exception e) {
19. System.out.println ("Error");
20. }
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 and Customer tables are available and each table has id column with a few records and the SQL queries are valid.
What is the result of compiling and executing this code fragment?

• A.The program prints employee IDs.
• B.The program prints customer IDs.
• C.compilation fails on line 13.
• D.The program prints Error.

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?

• A.Travel time is 4 hours
• B.An exception is thrown at line n1.
• C.Travel time is 8 hours
• D.Travel time is 6 hours

Given the definition of the Emp class:
public class Emp
private String eName;
private Integer eAge;
Emp(String eN, Integer eA) {
this.eName = eN;
this.eAge = eA;
}
public Integer getEAge () {return eAge;}
public String getEName () {return eName;}
}
and code fragment:
List<Emp>li = Arrays.asList(new Emp("Sam", 20), New Emp("John", 60), New Emp("Jim", 51)); Predicate<Emp> agVal = s -> s.getEAge() <= 60;//line n1 li = li.stream().filter(agVal).collect(Collectors.toList()); Stream<String> names = li.stream()map.(Emp::getEName);//line n2 names.forEach(n -> System.out.print(n + " ")); What is the result?

• A.John Jim
• B.A compilation error occurs at line n1.
• C.A compilation error occurs at line n2.
• D.Sam John Jim
