Introduction to Obiect-oriented Analvsis and Desion

1. (10 points) True or False. Answer either True or False. (a) (1 point) A good object-oriented (OO) design must use inheritance, especially multiple inheritance. (b) (1 point) Test-driven Development (TDD) and Iterative and Incremental Development (IID) work for the OO paradigm too. (c) (1 point) An Iterator class must raise Stopiteration exception somewhere. (d) (1 point) In Python, Dictionary, List, Set, and String are Iterable classes which allow the following uniform for-loop usage for x in iterable object. (e) (1 point) Generator is iterator, while iterator is not generator. A file object is an iterator. (f) (1 point) In Python, attributes and properties are different things. We can make a property by decorating a class method using Oproperty. (g) (1 point) An object must be something physically tangible. It cannot be a concept. (h) (1 point) Polymorphism can also be achieved through duck typing. (i) (1 point) The Unified Modelling Language (UML) is a useful tool in OO analysis and design. In real software development, programmers mechanically translate UML diagrams to code. A team is not professional enough if they do not draw lots of pretty UML diagrams. (j) (1 point) The OO paradigm is superior to the non-OO paradigm in terms of code maintainability, regardless of the programmer's skills
