private String s = s;//illegal forward reference error. What does it mean?



Well, it is an illegal forward reference because you are declaring a reference "s" and trying to initialize it to itself.


I am assuming that you wanted to initialize it to the "s" reference in the outer class? Which quite frankly may not be visible during this initialization.

Thanks for your reply.
Well, I read that "a method-local inner class can access private or any other members of its enclosing class." Based on this statement, I was trying to access a "private String s" variable of outer class. Is the above statement wrong?

Henry, look into this code now:

I can conclude that outer s is visible inside the method!

It is in the second example. But I was referring to your first example.
