- Laboratory Exercises – Java Lesson 5: Creating Classes and Objects 2. Write a program that displays the employees Ids together with their first and last names. Use two classes. The first class contains the employee data and separate methods to set and get the ID’s and names. The other class creates objects for the employees and uses the objects to call the methods. Create several employees and display their data 3. a. Create a class named Circle with fields named radius, area and diameter. Include methods names setRadius(), getRadius(), computeDiameter() which computes a circles’s diameter and computeArea which computes a circle’s area. The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius. b. Create a class named TestCircle whose main() declares three Circle objects. Using the setRadius() method, assign one circle a small radius value. Assign another circle a larger radius value and assign the third circle a radius of 1.

- Create a class car with make, model, year, OwnerName, RegisNo, Insurers as private fields. Create the following void methods getcarInfo, storeCarData and processcarInfo as public members of the class.• Start at the junction • Stop at AITCreate another derived class Commercial with car as it base class. The commercial class should have RegFees, Station,Route as it’s private member fields and CommeCar as it public method. At program execution stage the following methods are called in the main function getcarInfo, storeCarData of the base class and CommeCar.Using code snippets write a C++ program to solve the problem above. NB: All functions do not need function definitions but provide the function prototypesA library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…Create a class Car which contains members speed, noOfGear. The class has a method drive( ) which is responsible to provide starting speed and noOfGears to a Car. Implement display( ) method which will display all attributes of Car class.

- This way, any class that implements the Visible interface can define its own behavior for making an object visible or invisible based on its specific requirements.Create the Priority Java interface, which has the methods setPriority and getPriority. A method for determining numerical priority among a group of objects should be defined by the interface. Create and implement a class named Task that represents a task that implements the Priority interface, such as one that is on a to-do list. To test some Task objects, construct a driver class.The BankAccount class models an account of a customer.
