Problem Statement:Your university wants you to create a management system that will store employee data in the following hierarchy. Create the necessary classes that represent the following diagram: The attributes for each of the classes are provided in the diagram for your reference.In addition to the Staff, Management, and the Teacher classes, you need to create the Education class which should be associated only with the Teacher and the Management.You have to create a menu based application to store and display the data.The input options shall be 1 for Teacher, 2 for Management, and 3 for Admin.For each of these options you display the type of data being provided as input and request the user to enter the relevant information. For qualification, you shall provide them with options from 1-4 and once all the data has been provided, you shall then display the given information in a formatted output.Once the data has been displayed, you should then print "Staff being deleted..." in the Staff class's destructor.Please refer to the input and output section for more details.Input format :The input consists of an integer choice, followed by data related to a specific employee type (Teacher, Management, or Admin) based on the given choice.For Teacher:choice = 1Employee code (string)Employee name (string)Educational qualification (integer): (1: - Undergraduate, 2 - Graduate, 3 - Masters Degree, 4 - PhD)Subject (string)For Management:choice = 2Employee code (string)Employee name (string)Educational qualification (integer): (1: - Undergraduate, 2 - Graduate, 3 - Masters Degree, 4 - PhD)Management Grade (float)For Admin:choice = 3Employee code (string)Employee name (string)Department (string)Output format :The output displays the user information based on the user input, along with the "Staff being deleted..." message from the destructor.A new line space is given after the last line of the output.Refer to the sample output for the formatting specifications.Code constraints :The educational qualification should only be within the given range of 1 to 4The choice will be an integer between 1 and 3 (inclusive).Employee code, employee name, subject, and department will be strings with a maximum length of 20 characters.Educational qualification will be an integer (1, 2, 3, or 4).Management Grade should be an integer.Sample test cases :Input 1 :1ABC3343HarryPotter2WizardryOutput 1 :TEACHER The given information:Employee code: ABC3343Employee name: HarryPotterEducational Qualification: GraduateSubject: WizardryStaff being deleted...Staff being deleted...Staff being deleted...Input 2 :2KLD34RonWeasley34Output 2 :MANAGEMENT The given information:Employee code: KLD34Employee name: RonWeasleyEducational Qualification: Masters DegreeManagement Grade: 4Staff being deleted...Staff being deleted...Staff being deleted...Input 3 :3CMS34343HermioneCompsciOutput 3 :ADMIN The given information:Employee code: CMS34343Employee name: HermioneDepartment: CompsciStaff being deleted...Staff being deleted...Staff being deleted...Input 4 :4Output 4 :Invalid choiceStaff being deleted...Staff being deleted...Staff being deleted...Input 5 :2KLD34RonWeasley6532Output 5 :MANAGEMENTInvalid Educational Qualification. Try one more time.Invalid Educational Qualification. Try one more time. The given information:Employee code: KLD34Employee name: RonWeasleyEducational Qualification: Masters DegreeManagement Grade: 2Staff being deleted...Staff being deleted...Staff being deleted...Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.

Develop a Student Record Management System in Java for a university. The system should enable administrators to effectively manage student records, including adding new students, updating student information, and viewing student details.Requirements:Student Class:Create a Student class with private instance variables for storing student information such as name, ID, age, and grade.Student Management Class:Create a StudentManagement class with private static variables to store a list of students and the total number of students.Administrator Interface:Display a menu with options to add a new student, update student information, and view student details.Prompt the administrator for necessary inputs and perform the requested operations using the StudentManagement class.Error Handling:Implement error handling to handle cases where the student ID is not found or invalid inputs are provided.Documentation:Provide comprehensive documentationInclude instructions for running the program and interacting with the administrator interface.Remember to use appropriate variable names and follow coding best practices.

21. Write a Java program that creates a class hierarchy for employees of a company. The base class should be Employee, with subclasses Manager, Developer, and Programmer. Each subclass should have properties such as name, address, salary, and job title. Implement methods for calculating bonuses, generating performance reports, and managing projects

Q1. Create an Employee class with the relevant attributes and methods in addition of thefollowing specifications:  It contains a default constructor. It contains a parameterized constructor. It contains a copy constructor.Note: Each student should have different their own version and it is better to have morethe attributes and methods.Q2. Incorporate static attributes and static methods in the Employee class where required.note for chatgpt/bard : computer languages used for code is c#

A student management system has to be developed for a University. The University demands the following conditions to be incorporated in the system to efficiently handle the student information, including student IDs, names, and marks of three different subjects. Develop the student management system to ensure flexibility and scalability for enrolling new students.The conditions are given as follows.Store the student IDs, name, and the marks of three different subjects for n students using dynamic memory allocation. Implement a user-defined function by passing the address to display the information of each student.

t a university, 3 courses are offered: "Programming", "Databases" and "Software Engineering".Each course is offered by a lecturer.Create for each course an instance of type COURSE (=class) using a constructor (parameters: name of the course and the lecturer).The lecturer is stored in a data member of type LECTURER (=class). The class LECTURER should have at least the data member academic_title.The courses have a maximum of 10 and a minimum of 3 course participants.The courses can be attended not only by our own students, but also by students from other universities.The class STUDENT should have at least the following data members: Matriculation numberUniversityStudents from their own university may take any course.Students from other universities may only take one course.The classes LECTURER and STUDENT should derive from the class PERSON.The class PERSON should have at least the following data members:SurnameFirst nameEmailTask: Create a program with a menu that covers the following situation:1. Registration for a course (including querying student data). Each student has a unique email, meaning there can't be two or more students with the same email in the same course.2. Output of one/all courses with data of the participants.    Please note that if there are fewer than 3 participants in a course, an additional message must be displayed - "Course will not take place".3. Output of all courses that are not fully booked yet. The output must include the number of free places, the name of the course and the academic name of the lecturer with its academic title.4. End of program: A message will be displayed stating which participants (=all data members of the class PERSON) have to be notified because your course is not taking place.If necessary (creation, search, and so on), corresponding messages are to be displayed.Permanent storage of the data is not required. The data must only be available at the runtime of the program.Use comments in the source code to document your program.
