Question 5 (10 pts) In the UML class diagram below, class HouseBoat multiple-inherits from class Boat and class House since it shares the properties of a Boat as well as a House. a) You are required to implement the design in Java which does not support multiple-inheritance. Keeping reusability of classes Boat and House in mind, how would you redesign the hierarchy to implement it in Java? Show the UML diagram (no code is necessary). Boat and House are classes, do not make them interfaces in your re-design. b) In your re-design, is an instance of a HouseBoat substitutable for an instance of a Boat? (Yes/No) c) In your re-design, is an instance of a HouseBoat substitutable for an instance of a House? (Yes/No)
