Class A is the parent class, while classes B and C are the subclasses of A. Both B and C contain several features and techniques that are equivalent to one another; nevertheless, the implementations of some of their methods are quite different between the two. Explain what kind of class A will be using logic, whether it be a concrete class, an abstract class, or an interface.
Design and implement Java program as follows:(1) There will be a Gift class with following attributes: id (combination of numbers and letters),size (values S, M, or L), and price(2) There will be two child classes FruitBasket and SweetsBasket with the following additionalattributes: FruitBasket: number of fruits, include citrus fruits indication (true or false) SweetsBasket: include nuts indication (true or false)(3) The Gift class hierarchy must provide the following Functionality: On creation, a gift instance must be given all attribute values except price which must becalculated and number of fruits which must be set by system All attribute values can be changed after creation except id and the values that arecalculated or set by the system Price is calculated as follows:o There is a flat fee of 19.99 for S gift, 29.99 for M gift, and 39.99 for L gift.o Fruit basket gift has additional fee of 5.99 when it has citrus fruits. Number of fruits in a basket is as follows: Small…
Computer Science Create an inheritance hierarchy of Rodent: Mouse, Gerbil, Hamster, etc. In the base class, provide methods that are common to all Rodents, and redefine these in the derived classes to perform different behaviors depending on the specific type of Rodent. Create an array of pointers to Rodent, fill it with different specific types of Rodents, and call your base-class methods to see what happens. Write a small program to show the difference between calling a virtual function inside a normal member function and calling a virtual function inside a constructor. The program should prove that the two calls produce different results.

Implement all these classes while illustrating the concept of aggregation and composition in terms of ownership and life-cycle. Consider six classes i.e. Person, Department, Laboratory, and University having following specifications. Class University has Two attributes of type string i.e. universityName and location· An attribute named dept of type Department Class Department has Two attributes i.e. deptID, deptName· A two-argument constructor to initialize data fields with user-defined values· A member function display() to show all attribute values Class Laboratory contains Two attributes i.e. labID and experimentNo· A two-argument constructor to initialize data member with user-defined values Class Person has Two attributes i.e. name and age· A parameterized constructor to initialize attributes with user-defined values· A member function display() to show its attribute values
We discussed in the class that during the design, you may need a class that serves as an interface for its derived classes, but you would not create any instance of that class. Such a class is called an abstract class. The UML class diagram shown below shows a class hierarchy starting from the Vehicle class which is an abstract class. Write a program to implement this class hierarchy such that the given code in the main function runs without error. Vehicle Bus Car Truck IntraCityBus InterCityBus int main() { Vehicle* V[] = { new Bus, new Car, new Truck, new IntraCityBus, new InterCityBus }; for (int i = 0; i < 5; i++) { cout<< V[i]->move() <<endl; } return 0; } Your program should produce an output as the following: Bus: Moves to carry a large number of people Car: Moves to carry a small number of people Truck: Moves to transport goods Intra-City Bus: Intra-City Bus: Moves to carry a large number of people between two areas of a city Inter-City Bus:…
