Assume that a car must be owned by one owner and an owner can own many cars, but an owner might not own any cars. Also include subclasses for car like sports car, sedan, and minivan, with appropriate attributes.

- Question part 3: Draw a UML class diagram with all the classes and relationships. More info: In this last and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. (please see the photo if…Write a class Employee with attributes (employee_id, scale). The class contains member functions to input and show the attributes. Write a child class Manager that inherits Employee class. Child class has attributes of manager id and his depart. It also contains the member functions to input and show its attributesCreate 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…
- Create a UML Diagram based on the information below. Design a class hierarchy rooted in the class Employee that includes subclasses for HourlyEmployee and SalaryEmployee. The attributes shared in common by these classes include the name, and job title of the employee, plus the accessor and mutator methods needed by those attributes. The salaried employees need an attribute for weekly salary, and the corresponding methods for accessing and changing this variable. The hourly employees should have a pay rate and an hours worked variable. There should be an abstract method called calculateWeeklyPay(), defined abstractly in the superclass and implemented in the subclasses. The salaried worker's pay is just the weekly salary. Pay for an hourly employee is simply hours worked times pay rate. For reference following is the java code for some of the classes- //Employee// package employee; public abstract class Employee { private String name; private String jobTitle; public…For the order system with two classes Customer and Order: • Draw a UML class diagram that shows the relations between following classes in the order system. class attributes operations SendOrder(orderNumber =or50) reciveOrder(orderNumber) PayBill(amount) name Customer class Name (string) Id (string) Address (string) Date (date) Number (string) customer order Class Order Confirm Close generatePayment completePayment() Billld(string) Amount (double) Payment class Payment A Customer will send / recive an order and pay a bill to recive an order An Order will generate a payment for the order.
