Which two statements are true? (Choose Two)

A. An anonymous inner class can be declared inside of a method
B. An anonymous inner class constructor can take arguments in some situation.
C. An anonymous inner class that is a direct subclass that is a direct subclass of Object can implement multiple interfaces.
D. Even if a class Super does not implement any interfaces, it is still possible to define an anonymous inner class that is an immediate subclass of Super that implements a single interface.
E. Event if a class Super does not implement any interfaces, it is still possible to define an anonymous inner class that is an immediate subclass of Super that implements multiple interfaces.

Exhibit:

1. class A {
2. public String toString ()  {
3. return “4”;
4. }
5. }
6. class B extends A {
7. 8.   public String toString ()   {
8. return super.toString()  + “3”;
9. }
10. }
11. public class Test {
12.   public static void main(String[]args)  {
13.      System.out.printIn(new B());
14.      }
15. }

What is the result?

A. Compilation succeeds and 4 is printed.
B. Compilation succeeds and 43 is printed.
C. An error on line 9 causes compilation to fail.
D. An error on line 14 causes compilation to fail.
