- 3. Dependency Inversion Principle: high-level modules should not depend upon low level modules. Both should depend upon abstraction. The following code is an implementation of a login function for MySocialNetwork, but it violates the Dependency Inversion Principle. a. Explain why the code violates the Dependency Inversion Principle b. Rewrite the code to make it conform with the principle public class My HCMIU Email { public void loginWithStudentID(String username, String password) { */ } } public class MySocialNetwork { private My_HCMIU_Email loginService; public void SetLoginService (My_HCMIU_Email value) { loginService = value; } public bool login (String username, String password) { return loginService.loginWithStudentID(username, password); } }Define a class for the marks (student subject marks) that includes the following data members: A (OOP) B (Data Structures) C (Calculus II) The class also contains the following member functions: Insertion function – to get three values (courses). Sum - to sum up three values (courses). Ave – to give average of the three values (courses). Display function - to display sum and average. NOTE:subject: object oriented programming(oop) Deptt:CS/ITQuestion 2 (Student Inheritance Hierarchy) Draw a UML class diagram for an inheritance hierarchy for students at a university similar to the hierarchy shown in Fig. 11.2. Use Student as the base class of the hierarchy, then extend Student with classes UndergraduateStudent and GraduateStudent. Continue to extend the hierarchy as deeply (i.e., as many levels) as possible. For example, Freshman, Sophomore, Junior and Senior might extend UndergraduateStudent, and DoctoralStudent and MastersStudent might be derived classes of GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes.

In the process of recognition (or categorization), images are first transformed into a multidimensional fea- ture space and then, using machine-learning techniques, are categorized into a finite number of classes. Application areas of image recognition and categorization range from agriculture to homeland security, personalized marketing to environmental protection. Image recognition is an integral part of an artificial intelligence field called computer vision. to be done to reach human-level performance. Current approaches are capable of dealing with only a limited number of categories (100 or so categories) and are computationally expensive. Many machine-learning techniques (including ANN, SVM, and kNN) are used to develop computer systems for visual…
- Object Oriented Programing Consider the following details of all classes in diagram A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classes.3 (a) Use the class diagram to answer the below questions.
