For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.
You are given the following class and the client class. Examine the code and provide the output of the client class. Explain the intention of the code and comment if the code output matches the intended use of the code. Explain any mismatch between intention and actual code output. Find the problem in this code and explain what you would do to solve the problem. The Person class is shown in the UML class diagram as follows. System.out.println("Name: System.out.println("Age: System.out.println("Weight: " + weight + " kg"); " + name);" + age + " years"); Person - name: String + setName(String newname): void+ getName( ): String+ writeOutput ( ): void+ equals (Person otherPerson): boolean /** This is the class that can be used for the client class */ public class Twin { private Person first, second; public Twin(Person firstPerson, Person secondPerson) {first = firstPerson; second = secondPerson; } public Person getFirst() { return first; } public…
Which statement of the following is the most appropriate? Group of answer choices When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the botttom of the implementation file for easy reference.

Suppose we have an program which is a Human Resources system used to hire and track new employees. One class in the program is the Employee class. Other classes include Payroll, Supplies, Vendors and Trainers. Consider just the Employee class itself. Which of the following data fields and methods would be appropriate to include in the Employee class and any classes extended from Employee? Hint: Think about object oriented design principles, and locating data fields and methods in classes to which they directly belong and associate to. O first name O hire date O Office Address O Company Lax ID O Supplier tax ID O Vendor Invoices O birth date O employe ID number
Consider an online holiday booking system. The users can register and log in to book a holiday package. Currently, the holiday packages offered to users include ski and cruise packages. Which of the following is the most appropriate for an object-oriented design? Select one: O a. The classes, Ski and Cruise, should be modelled in the aggregation association with the Package class. O b. The classes, Ski and Cruise, should be modelled as sub-types of the Package class. O c. The classes, Ski and Cruise, should be modelled as the interface classes to the Package class. O d. The classes, Ski and Cruise, should be modelled in the composition association with the Package class.
In UML class diagram given below, which attributes and behaviors of the Animal class would be inherited by the Dog class? Animal int # numberOfLegs: # numberOfTails: int # name: String + walk() + run() + eat() + playFetch() Dog A None of the attributes and behaviors are inherited B numberOfLegs, numberOfTails, walk(), run(), eat() (c) All attributes and behaviors of Animal are inherited playFetch()
If you are designing an application for a car dealership, you will create a Vehicle parent class and then extend the class into Car, Truck, SUV child classes. The Vehicle class will have the general attributes and behaviors. Then, you only need to code the specific differences in the child classes. Give us an example of objects that might have similar attributes and behaviors but enough differences to warrant an inheritance relationship. Then, explain the relationship and teach your classmates about inheritance.
Select the class relationship that best describes the following scenario: • Class A accepts an instance of Class B as a parameter in one of its methods. • Class A then uses one of the Class B's methods. Association (Reflexive) Association (Bidirectional) Association (Directed A to B) Association (Directed B to A) Composition (A as the whole and B as the part) Composition (B as the whole and A as the part) Aggregation (A as the whole and B as the part) Aggregation (B as the whole and A as the part) Inheritance None of the given
Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…
