Java invoker

In Java, is it possible to get the invoker of a class? I am trying to create two classes simultaneously but I want them to reference each other, preferably upon creation(constructors) if possible. I know I can sort of do it by returning the stack trace, but this doesn't exactly seem... proper. Any ideas /prog/?

Yeah. Keep talking about the other class out of the class itself. It sort of breaks that abstraction.

This is why a lot of people hate Java. Is Java your first language?
