Accessing enclosing class' super class in inner

How do you access enclosing class' super class variables.
I know about <outer>.this.<variable>
Is there such a thing like <outer>.super.<variable>

Look at the code below -

class SuperA {String s1="SuperA";}
class SuperB {String s1="SuperB";}
class A extends SuperA {
String s1="A";
class B extends SuperB { // 1
String s1="B";
void m1() {
System.out.print(this.s1 + ","); // 2
System.out.print(super.s1 + ","); // 3
System.out.print(A.this.s1 + ","); // 4
System.out.print(A.super.s1); // 5
}
}
public static void main (String[] args) {
new A().new B().m1(); // 6
}}

What is the result of attempting to compile and run the program?

a. Prints: B,SuperB,B,SuperB
b. Prints: B,SuperB,A,SuperA
c. Compile-time error at 1.
d. Compile-time error at 2.
e. Compile-time error at 3.
f. Compile-time error at 4.
g. Compile-time error at 5.
h. Compile-time error at 6.
i. Run-time error
j. None of the above

Have you tried compiling and running the program? In Java you unequivocally should get the same result I do.

Yes, to answer such a question as Is there such a thing like <outer>.super.<variable>? you can compile the code to find out. (Took 30 seconds to do so ).

Getting someone to think and try something out is much more useful than just telling them the answer.
