- Programming to be used: Java Instructions: Develop a UML class diagram for the following situations. Your diagram should be able to specify correctly the following: Class Name, Attributes with their corresponding data type and visibility, Methods with their corresponding data type. Use the text editor or MS word to present your answers. Scenarios: 1. The university wants you to design an enrollment system. One of the classes to be considered is class STUDENT. A student during registration can have his ID number. Information about the student (eg. First name, middle name, middle initial, contact number, address, birthday) are asked and stored in the system. These information, however, can be edited. After the registration/admission, a student can enroll subjects, can add subjects and can drop subjects. 2. The same University asks you to design a Human Resource Information System. This is a system that records information and generates reports about the employees in the university. Each…3 (a) Use the class diagram to answer the below questions.

Nominate the classes that are connected with certain relationship c) According to Figure 1 is it possible for a given print to be entered for more than one competition? Explain your answer d) Interpret the association between Member and Cclub classes.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…

Add the cardinalities, the attributes, and the methods that you believe relevant in the classes. we are interested in the management of horse race events. A race could be local or international. It is held in a given location and organized by one or more organizers. An organizer could be of two types: event organizer or local organizer. For every race there will be exactly 3 trophies. Several horses participate in a given race. A horse has a type. It is trained by one and only one trainer. It is also ridden by one and only one racer. For every race, there will be a result assigned to every horse. A racer may have received several trophies. For every trophy received, the date of awarding is stored. Racers are organized into teams. A team may include several racers. One of these racers is appointed as leader. Every team of racers has a chief trainer. The chief trainer has the role of supervisor (i.e.…
- Task 4 Develop a class diagram for following description: Develop a class diagram for following description: The telephone agent uses an order registry and customer catalog to obtain access to an order & a customer respectively. The order registry uses an order number as a qualifier to select particular order instance. A customer catalog uses customer name and phone number as a qualifier to select particular customer. The attributes of an order are the order numbers and time when it is placed. The order consists of many items. An item has item_number, a quantity, unit price. It also has reference to catalog item which represents listing. When an order is cancelled or corrmitted, it cancels or commits each of its items first. When an order's total price method is invoked, the order calls the total price method of each of items and returns the sum.programming language : C++ subject : object oriented programming question: We know that an Organization consists of Managers and Employees.

- java Prompt Create a UML diagram modeling any classes and relationships that you want. The classes and relationships used should make sense for a program that is modeling your chosen classes. Your model must have at least four classes and one example of abstract inheritance (abstract classes or interfaces), but there is no maximum limit to your diagram's size or complexity. Provide enough members inside of each class that it is clear what a program that uses these classes might be trying to accomplish. Think about what kinds of objects you might want to model in your code. Are you modeling real objects, or abstract ideas? Is there a type of classification you can use that would make it easy to come up with derived classes? What types of variables and methods would your classes need to be functional or work together. Your classes don't all need to be linked by inheritance - maybe you can come up with multiple different object types that work together in a larger program? An easy way…Create a UML Class Model based on the requirements .
