#1. Given: AnInterface is an interface.
AnAdapter0 is a non-abstract, non-final class with a zero argument constructor.
An Adapterl is a non-abstract, non-final class without a zero argument constructor, but with a constructor that takes one int argument.
Which two construct an anonymous inner class? (Choose two.)

 9. return super.toString() + “3”; 
 10. } 
 11. } 
 12. public class Test { 
 13. public static void main (String[] args) { 
 14. System.out.printIn(new B()); 
 15. } 
 16. }

What is the result?

 9. return 2; 
 10. } 
 11. 
 12. public short getNumber() { 
 13. B b = new B(); 
 14. System.out.printIn(b.getNumber()); 
 15. } 
 16. }

What is the result?

#5. Given:

 1. public class Foo { 
 2. public static void main(String[] args) {

 10. y = x; 
 11. } 
 12. }

What is the result?

 2. private static int a: 
 3. 
 4. public static void main (String [] args) { 
 5. modify (a) : 
 6. System.out.printIn(a) { 
 7. } 
 8.

 6. return true: 
 7. } 
 8. 
 9. public static void method A (int i) { 
 10. Boolean b; 
 11. b = I < 10 | method b (4): 
 12. b = I < 10 || methodb(8): 
 13. } 
 14. 
 15. public static void main (String args []) { 
 16. method A (0); 
 17. System.out.printIn(i); 
 18. } 
 19. }

What is the result?

#8. Which two are equivalent? (Choose two.)

#9. Given:

 1. public class X { 
 2. public static void main (String [] args) { 
 3. byte b = 1277; 
 4. byte c = 126; 
 5. byte d = b + C; 
 6. } 
 7. }
