Assume different members and methods of a real world class is grouped or embedded into a single element. This is called in Object-Oriented Programming language Select one: a.Inheritance b.Polymorphism C.Encapsulation d.Abstraction
Map each of the keywords on the left to the statement that describes it the best. Inheritance Class Object Polymophism Instance variable [Choose ] ✓ It is any variable that does not represent a living being. It allows properties and functions to be passed to another object when an object is deleted. It represents a blue print of an object. It is like a global variable that can be accessed in all functions of a program. It is a category to organize variables and objects in groups. It is an instance of a class. It is a programming command with a special meaning. Classes can acquire properties and functions from other classes. It is a property inside that class that exists throughout the lifetime of an object. It is used to define the relationship between classes. It is a variable of a primitive type. It is a variable that can store values of multiple types. It allows a variable of a super class type to be assigned an instance of a subclass type. It is used to describe that a class…
Classes in the same inheritance hierarchy typically belong in the same package. Select one: True False
The module view of inheritance refers to: Dynamic binding Every operation applicable to the instances of a superclass is also applicable to the instances of its subclasses. A subclass describes an extension of the parent module O A subclass describes a subtype of the parent type Which statement about encapsulation is incorrect. Encapsulation provides a way to cope with change Encapsulation conceptualizes a problem at a higher level of abstraction Encapsulation facilitates software maintenance O Encapsulation conceptualizes a problem at a lower level with specific data structures O O
Inheritance is an OOP concept such that a class can be defined in different ways, such as either being typecasted to itself (as a subclass) or any of its superclasses. True False
How is sub-typing distinct from inheritance? Group of answer choices Sub-typing is a has-a relationship where inheritance is a is-a relationship. They are different names for the same concept. Object-oriented programming uses inheritance, where non-object oriented languages use sub-typing. Inheritance involves reuse of implementations, where sub-typing involves having a shared list of operations that the type can do.

Computer Science Object Oriented Analysis and Design. Look at the problem described below and describe how you would break it into objects, consider ways to use inheritance and composition. Describe for me how those objects make a system of objects that solves the problem. You may use UML or just write out a list of classes describing their properties and interface. You should also include a short description of how those objects work together. A local travel agent has built a business on using their knowledge of Europe to create custom trips for couples around Europe. For each client they create customized itineraries (a planned route or journey) and book all the travel and lodging accommodations for their high-end clients. For example they might build a custom vacation in Scotland where the client flies into St. Andrews and stays at a castle for 1 night then takes a bus to Pitlochry where they stay at a hotel for 3 nights then take a private plane to Braemar where they stay in a…
It is required to provide an explanation of the many different kinds of inheritance.
Overview The objective of this assignment is to demonstrate an ability to implement inheritance, composition, and overloaded operators in a program. This program leverages many of the concepts that you have learned in this class and combines them into a professional-style program. Instructions Classes are getting to be more realistic with each programming assignment. This assignment includes the valuable aspect of inheritance to facilitate reuse of code and operator overloading to allow the usage of familiar operators tailored specifically to the Person, Student, and Faculty classes. Composition is also demonstrated in the use of a Course class that contains objects of the Student and Faculty classes. You are working in the IT department for a university and have been tasked with developing an application that will manage the registration process, which involves the creation of a course, the enrollment of students in the course, and the assignment of faculty members to teach the…
Q# In the company example, a supervisor has a supervisee. This “has-a” relationship is called: Group of answer choices 1. parent 2. composition 3. extending 3. inheritance
language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…
