Q) Write a Class Person that has data members of ID, name and address. The class contains member functions for input and display the data members. Create second Class student that inherits person class. It has additional data members of roll number and marks. It also has member functions for input and displays its data members. 1) Create an object to read and display all data of the classes. 2) Specify the type of inheritance. 3) Is it possible to convert the above program to another type of inheritance(explain with example)

In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
Q3: Class called ( myclass) and an objects of this class called (obj1) and (obj2). This class contains two data members of type integer (a and b) with private access, and three member functions with public access: constructor to give valne to variables, and default constructor and show0 to display variables. Write a program to set and display the objects fields.
Design and implement a Class time which has a constructor and destructor member fuction. Your class should use multiple constructor and destructor. a. Enlist data members and methods with access specifies b. At least one member fuction and data members should be constant.
Step 1. Start the programStep 2. Create a class student which contains primitive data members.Step 3: Define a constructor to initialize the data members.Step 4: Define the methods get and display to get and display the data members.Step 5: Create object for the class to access the member functions.Step 6: Display the resultStep 7: Stop the program.Calculate the grade book;
Problem Statement with Hints 1. Write classes to hold Account, SB - Account and Current - Account details. [Here implement the concept of inheritance.] The common properties of the account are Account number, name and amount. Specifics of SB account is 4% interest to be paid per month.  Implement the run - time polymorphism by creating base class variable and derived class object.  Ask the user for which type of accou nt to be created then create the corresponding account (Note: Use scanner class).  Implement function overriding by having deposit and withdraw functions and perform the required action accordingly. Ensure base class can’t be instantiated. (Note: Abstract k eyword can be used). 2. Define the minimum balance for the both the type of accounts. Use final keyword to create constants. Ensure sb account class and current account class will cannot be used as base classes (Note: You can use final classes).
Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.
Assume the following Classes exist: Class A, B, C, D and E. Assume Class D is the child of Class A (inheritance). Assume Class A has a variable x with an access modifier set to "protected*. Which of the five classes can access the variable x?
Define two classes A and B each having one String private data member. Write zero argument and parameterized constructors to initialize the data member and member functions to get, set and display the data member for these classes. In the demo class, write a concat() function which takes the 2 arguments as class A and class B objects and concatenates the data ac members of these two objects. Write main method that creates instances of the classes A and B, assigns values to each and concatenates the value of data member of these objects using the concat() function. Display the objects before and after concatenation.
Activity - Abstract Class An English teacher wants to find assessment mark of all the students in his course. Write a java program to find assessment mark of the students using following instructions. Save the project/file as StudentAbstract. A) Abstract Class name: Assessment Abstract Member Method: - to calculate and return total score totalScore() B) Class name: English extends Assessment Member variables: QuizMark, PracticeTest, ListeningMark Member Method : - Constructor to initialize member variables - to calculate and return total score totalScore QuizMark + PracticeTest*0.25 + %3D ListeningMark/2 C) Controlling class : StudentAbstract - To create an object of English class - To print totalScore of the English
People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…
Define a class called student that has thefollowing data members: - int student number- string student name- double student averageThe following member functions:- Constructor that initialize the datamembers with default values. - set and getfunctions for each data member- Print function to print the values of data members.
Inheritance and UML (Java) Design a class named Employee. The class keeps the following information in fields: - Employee Name - Employee Number in the format XXX-L, where each X is a digit within the range 0-9 and the L is a letter within the range A-M. - Hire Date - Shift (an integer) - Hourly pay rate (a double) Write one or more constructors and the appropriate accessor and mutator methods for the class. The workday is divided into two shifts: day and night. The shift field will be an integer value representing the shift that the employee works. The day shift is shift1 and the night shift is shift 2. a) Draw a UML diagram of the class. Be sure to include notation showing each field and method’s access specification and data type. Also include notation showing any method parameters and their data types. b) Write a program that demonstrates the class.
