Question 3 Not Yet Answered Marked Out Of 7 00 Flag Question Marcia Is Responsible For Designing A System That She Knows 1 (95.05 KiB) Viewed 12 times

Question 3 Not yet answered Marked out of 7.00 Flag question Marcia is responsible for designing a system that she knows will be subject to frequent requests for additional functionality. The system she is developing will comprise objects of many varied types and the methods used are likely to be applicable across any number of these objects. Marcia is keen on software quality and reuse is a big consideration for her and the organisation she works for. With that in mind Marcia would like to ensure that the system is capable of facilitating extensions to behaviour without significant structural changes. Based on the above scenario, choose one or more of the following which is more appropriate for Marcia. a. Marcia should use the Visitor design pattern as this allows uncoupling of algorithms from the objects on which they operate. b. Marcia should make extensive use of inheritance and overloading. C. Marcia should use the Proxy design pattern as this allows for the substituting one object for another. d. Marcia should use the Prototype design pattern as this allows for copying objects in a way independent of classes and thus saving time. Maria should write the code so that all methods are in the same class so as to avoid having to modify many classes based on requests for new functionality.
