How you inherit the properties of two classes (not interfaces) in a child Java class. Where as those two parent classes are not related and not of any inheritance relationship between them.

4 Answers

My answer is, unlike other OO languages like C++ multiple inheritance is not possible in Java, and interfaces can be used to achieve this with specific implementation. The interviewer is not convinced with this.

The answer is composition inheritance. It's not as convenient as implementation inheritance (extends keyword) but creating an instance of the parent object and making the child manage/expose necessary members. Probably be a good idea to create an interface to keep things.

You would be using the Adapter Design Pattern.
