I know that Java does not allow us to extend more than one class. I know that interfaces also exist and I don\'t want to use them this time. Is there some kind of trick or w

go for interfaces.No multiple inheritance in Java.

JAVA omits many rarely used, poorly understood, confusing features of C++ that in our experience bring more grief than benefit. This primarily consists of operator overloading (although it does have method overloading), multiple inheritance, and extensive automatic coercions _ Dr. James Gosling
