Use of this and super in interfaces

[Deepak M]

class Test {
int i;
}
interface C {
Test t = new Test() {
int i = super.i;
};

}
The above code does not compile with JDK1.2.2. But it does with jikes.
Does it compile with jdk1.3 ?
Is there anything wrong with the code ?

Deepak,
You can use "super" only in a derived class. So if you say "class C extends Test" then you can use super.i in "C". For argument sake you CAN use super in any class since all are implicitely derived from Object but then you can only call methods of the Object class.

I AM using super in the derived class of Test.
Test t = new Test() {
int i = super.i;
};
Here, the anonymous class in the initilizer of the constant field 't' has Test as the super class.
Therefore, super is allowed here. Hence it DOES compile with jikes.
Refer JLS 9.3.1:
If the keyword this (�15.8.3) or the keyword super (15.11.2, 15.12) occurs in an initialization expression for a field of an interface, then unless the occurrence is within the body of an anonymous class (�15.9.5), a compile-time error occurs.

There is nothing wrong with the code, JDK 1.3 compiles it OK.
