Question 1

Given the code fragment:
Path p1 = Paths.get(“/Pics/MyPic.jpeg”);
System.out.println (p1.getNameCount() +
 “:” + p1.getName(1) +
 “:” + p1.getFileName());

Question 2

Given:
class FuelNotAvailException extends Exception { }
class Vehicle {
 void ride() throws FuelNotAvailException { //line n1
 System.out.println(“Happy Journey!”);
 }
}
class SolarVehicle extends Vehicle {
 public void ride () throws Exception { //line n2
 super ride ();
 }
}
and the code fragment:
public static void main (String[] args) throws FuelNotAvailException, Exception
 {
 Vehicle v = new SolarVehicle ();
 v.ride();
}
Which modification enables the code fragment to print Happy Journey!?

Options :
Answer: B
Question 3

Given the code fragment:
List<String> empDetails = Arrays.asList(“100, Robin, HR”,
 “200, Mary, AdminServices”,
 “101, Peter, HR”);
empDetails.stream()
 .filter(s-> s.contains(“1”))
 .sorted()
 .forEach(System.out::println); //line n1

Question 4

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.
