OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Consider an online holiday booking system. The users can register and log in to book a holiday package. Currently, the holiday packages offered to users include ski and cruise packages. Which of the following is the most appropriate for an object-oriented design? Select one: O a. The classes, Ski and Cruise, should be modelled in the aggregation association with the Package class. O b. The classes, Ski and Cruise, should be modelled as sub-types of the Package class. O c. The classes, Ski and Cruise, should be modelled as the interface classes to the Package class. O d. The classes, Ski and Cruise, should be modelled in the composition association with the Package class.
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.
It is necessary for a subclass of an abstract class to implement all of the abstract methods that are defined for the parent class. Is there a mistake or is it accurate?
Consider an online holiday booking system. The initial design model contains the classes, Booking, Individual_Booking and Group_Booking via inheritance.

Class Relationships Exercises 1. In Java, we use inheritance for "is-a" relationships. Containment, on the other hand, indicates that one object has another object. These are "has-a" relationships. For the following relationships, determine if they are a "is-a" or a "has-a" relationship: o bicycle - vehicle o car - engine o pizza - topping o food - pizza o dog - mammal 2. Share with someone else 3 other examples for each of the following relationships: o Inheritance ("is-a" relationship) o Containment ("has-a" relationship) 3. public class PersonInfo { protected String firstName; protected String birthdate; } public class ChildInfo extends PersonInfo { private String schoolName; } public class MotherInfo extends PersonInfo { private String spousename; private ChildInfo children1; private ChildInfo children2; private ChildInfo children3; ... } A.
