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

For which three objects must a vendor provide implementations in its JDBC driver? (Choose three.)

• A.Connection
• B.Time
• C.SQLException
• D.Statement
• E.DriverManager
• F.ResultSet
• G.Date

Given the code fragment:

What is the result?

• A.Java EEJava EESE
• B.The program prints either:Java EEJava SEorJava SEJava EE
• C.Java EEJava SE
• D.Java EESE

Given the code fragment:
public static void main (String[] args) throws IOException {
BufferedReader brCopy = null;
try (BufferedReader br = new BufferedReader (new FileReader("employee.txt"))) { // line n1 br.lines().forEach(c -> System.out.println(c)); brCopy = br;//line n2
}
brCopy.ready(); //line n3;
}
Assume that the ready method of the BufferedReader, when called on a closed BufferedReader, throws an exception, and employee.txt is accessible and contains valid text.
What is the result?

• A.A compilation error occurs at line n1.
• B.The code prints the content of the employee.txt file and throws an exception at line n3.
• C.A compilation error occurs at line n3.
• D.A compilation error occurs at line n2.

Given:
1. abstract class Shape {
2. Shape ( ) { System.out.println ("Shape"); }
3. protected void area ( ) { System.out.println ("Shape"); }
4. }
5.
6. class Square extends Shape {
7. int side;
8. Square int side {
9./* insert code here */
10. this.side = side;
11. }
12. public void area ( ) { System.out.println ("Square"); }
13. }
14. class Rectangle extends Square {
15. int len, br;
16. Rectangle (int x, int y) {
17. /* insert code here */
18. len = x, br = y;
19. }
20. void area ( ) { System.out.println ("Rectangle"); }
21. }
Which two modifications enable the code to compile? (Choose two.)

• A.At line 9, insert super ( );
• B.At line 20, use public void area ( ) {
• C.At line 17, insert super (); super.side = x;
• D.At line 1, remove abstract
• E.At line 17, insert super (x);
• F.At line 12, remove public
