Which of the following is the feature of Object-Oriented Programming described the reusability of code? Encapsulation and abstraction are meant to hide/group data into one element. 4. Which feature of OOP indicates code reusability? A. The attributes specified in the class may have unique values for each object. Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. We can solve real-world problems if we are using object-oriented programming. Encapsulation keeps state private so that we can better enforce . Let's create a . The power of object-oriented systems lies in their promise of code reuse. Observer b. As hardware and software became increasingly complex, manageability often became a concern. With the help of inheritance, a superclass's . Method overriding is used in runtime polymorphism. Object-oriented programming (OOP) is the most prevalent programming paradigm. This means we can add new features to an existing class without having to modify it. Sanfoundry Global Education & Learning Series Object Oriented Programming (OOPs). Were expected to make two distinct sorts of polygons: a Rectangle and a Triangle. Removing access to parts of your code and making things private is exactly what Encapsulation is all about (often times, people refer to it Polymorphism and overloading: A. Hipparchus Hipparchus Between 162 and 127 BC, he was known to be a working astronomer. Object-oriented programming (OOP) is defined as a programming paradigm (and not a specific language) built on the concept of objects, i.e., a set of data contained in fields, and code, indicating procedures - instead of the usual logic-based system. Explanation: Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. OOP is a striking shift from LP. OOP promotes the reusability of code. a) Inheritance The idea of write once, run many, also known as code reusability, is an important characteristic to the programming paradigm known as Object-Oriented Programming (OOP). Object-oriented programming combines a group of variables (properties) and functions (methods) into a unit called an "object." Data hiding is a characteristic of object-oriented programming . OOps in java is to improve code readability and reusability by defining a Java program efficiently. 9) Which feature of OOPS described the reusability of code? Object-Oriented Programming (OOP) is a programming concept in which a programmer uses classes and objects to implement real-world things in software development, such as inheritance, hiding, and polymorphism. Take, for example, your mobile phone. Question 38 (2 points) Which Feature of OOP boost the code reusability? The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. Which concept allows you to reuse the written code? described here along with there mapped relevance with VHDL. Object oriented programming can be described as a programming model which is based upon the concept of objects. Because a polymorphic object can operate on a variety of values and types, it can also be used in a variety of programs, sometimes with little or no change by the programmer. Notify me of follow-up comments by email. Sort the Array in Ascending order (default). Which feature of oops is described as the reusability of code? Static and Dynamic polymorphism ( Runtime Polymorphism ) . (15 marks) B5 a) Describe TWO features of object oriented programming languages that promote code reuse. Constructors may be overloaded, which means that multiple argument lists can be used with the same name. The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. Inheritance is relevant due to the concept of Code Reusability. Code Reuse: Functions and Modules Reusing code is key to building a maintainable system. OOP is a striking shift from LP. This is what abstraction is. An object-oriented programming is a way programming which enables programmers to think like they are working with real-life entities(a thing with distinct and Inheritance is a fundamental feature of an Object-Oriented programming. One of the most important and essential features of object-oriented programming in C is data abstraction. Member variables or instance variables facilitate a class instance to maintain its position. As a result, he brings him to the range with his favorite rifle and teaches him how to aim and fire at targets. However, the advantages of object-oriented programming are many. a programming language model in which programs are organized around data, or objects, rather than functions and logic. Overview of OOP in Java. 3. The important features which are help to design the object-oriented programming and design is given below: Development over the designed programming paradigm. Modularity ensures re-usability and thrives to minimize the duplication. It doesnt support multiple inheritance. Encapsulation and abstraction are meant to hide/group data into one element. Simply classes consequently define the type of their instances. If you wish to learn the most in-demand Programming Languages to help you optimize your job opportunities check out the Programming courses from Intellipaat. (10 marks) b) Name THREE different types of polymorphism commonly available in object oriented programming languages, giving code examples to support your answer. In each application you create, you may employ a variety of objects of various sorts. Abstraction in header files: An another type of abstraction is header file. 9) Which feature of OOPS described the reusability of code? The purpose of encapsulation and abstraction is to hide/group data into a single unit. Chapter 4. 2. Object . Write unit tests for your classes AND make it easy to test classes:-, Remove logic or main code away from any framework code:-, Try to think more abstractly and use Interfaces and Abstract classes:-. The class that provides its attributes is known as the base class and the class that accepts those attributes is known as a derived class. Answer: (c). It is a user-defined data type that holds data members and member functions in a single unit. The ability to reuse existing objects is considered a major advantage of object technology. For example, MyCar and goldenRetriever are two particular instances of the abstract class. Code reuse may not be exactly what people think. Object-oriented programming necessitates planning and thinking about the programs structure before starting to code and examining how to decompose the requirements into basic, reusable classes that you may utilize to create object instances. When you inherit from an existing class, you can reuse methods and fields of the parent class. The following are the concepts in OOPs-Object; Class; Inheritance . Q) Which C++ oops feature is related to re-usability? This concept is often used to hide the internal state representation of an object from the outside. 10. in cpp, members of a class are ______ by default. These are the following OOPs features. Which among the following, for a pure OOP language, is true? However, an object cant be simply declared as same as primitive types. Click again to see term . Classes are organized into hierarchies, and inheritance enables one classs structure and functions to be transferred down the hierarchy. Objects are the basic run-time entities in an object-oriented system. Other objects dont have direct access to this state. 11. a) Abstraction b) Encapsulation c) Polymorphism d) Inheritance* 10) Which operator from the following can be used to illustrate the feature of polymorphism? This OOPS feature inherits the features of another class in the programs. Abstraction, encapsulation, inheritance, and polymorphism are four of the main principles of object-oriented programming. Explanation: Platform independence is not included in the OOPS concepts. Which feature of OOP indicates code reusability? Whereas LP has data structuresessentially variables that contain an arbitrary composition of native types such as float or integerOOP extends the data structure concept to describe a whole object. Encapsulation: This option is incorrect because encapsulation is a feature of binding code and data in a single unit. Methods and attributes only available from other methods in the same class make up the private/internal interface. Create two files for each class using the C/C++ convention: a header file for the classs code (. But that is not the topic of discussion. Reusability of the code can be achieved in CPP through inheritance. Answer: c. Explanation: For the feature given above, the OOP feature used is Polymorphism. Example of polymorphism in real life is a kid . 3. The Object oriented programming makes it easier to the programmers to design and organize software programs. Which among the following doesnt come under OOP concept? Question 4. There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . d) Functions Overloading To practice all areas of Object Oriented Programming (OOPs) using C++, here is complete set of 1000+ Multiple Choice Questions and Answers. Code duplication is avoided, and reusability is increased. THE MAPPING It is observed that VHDL also corresponds to some features of Object Oriented Designs and Object Oriented Programming Structure (OOPS) like abstraction, encapsulation, reusability, polymorphism, concurrency etc. Polymorphism is to indicate different tasks performed by a single entity. For example, if the file name is prime.py, the module name is prime. 1. It is the process of creating a new Class, called the Derived Class, from the existing class, called the Base Class. c) It depends on type of program Select one: True False What is the pattern used in Java I/O library Select one: a. The son, on the other hand, was astute and chose to flip his fathers hands, putting his dominant hand on the trigger rather than the fathers. View the full answer. b) 6 When a child class overrides a parent classs method, the child class might offer an alternative implementation. Generics in Ada and classes in object-oriented languages promote code reuse. The module name is generated out of the file name by removing the suffix ".py". It enables code reusability by allowing a new class. What are the basic principles of OOPs? inta public toata a) Error: same vanable name can be used twice b) Error Public must come first C) Error: data types are different for same variable d) It is correct 3. Object-Oriented Programming or OOPs is a programming paradigm that revolves around the concept of object, which contains properties and methods. It provides the ability to inherit attributes and behaviours from one class to another class. Because an object can only be associated with data in predefined classes or templates, the object can only "know" about the data it needs to know about. View Answer, 14. We also have no idea how a bike works on the inside. c) Abstraction. Characteristics of Object Oriented Languages. Which feature of OOP indicates code reusability? Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. Classes may inherit characteristics from other classes thanks to inheritance. Because of their differing orientations, the father was concerned that he may not be able to teach his son how to shoot. But we dont know internally what things are happening inside ATM machine when you insert an ATM card for performing any kind of operation. Consider the following scenario: you wish to store two numbers for one individual. In OOP, what is the concept of reusability? Classes are commonly used to indicate large groupings with similar characteristics. a) Polymorphism b). Create a function that will accept as arguments two integers and the name of the individual to some function void createContact that will be defined later (String name, int number1, int number2). In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software,: 7 following the reusability principles.. Code reuse may be achieved by different ways depending on a complexity of a programming language chosen and range from a lower-level approaches like code copy-pasting (e.g . Inheritance. That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity. This mechanism actually inherits the fields and methods of the superclass. Java OOP. In Java, there are many methods for creating objects, including the new keyword, the newInstance() method, the clone() method, the factory method, and deserialization. Say we have a program. This makes the code less redundant and more flexible to use in different classes. Which reusability-related C++ OOPS feature do you use? This OOPS feature inherits the features of another class in the programs. View Answer, 2. By doing this, we are reusing the fields and methods of the existing class. Abstraction is a concept of object-oriented programming that hides unnecessary information while only showing essential attributes. which feature of oops described the reusability of code? List types of behavior models. Polymorphism Abstraction Encapsulation Inheritance. Encapsulation Polymorphism Inheritance Abstraction Question 39 (3 points) Write the Java code to declare an Array called "studentScoresArray" that contain scores (100, 55, 77, 22, 44, 88). These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. java reusability. In laymans terms, the attributes that you inherit from your parents are a simple illustration of inheritance. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or super class or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class. a) Encapsulation. Answer. Object-Oriented Programming (OOP) is a programming concept in which a programmer uses classes and objects to implement real-world things in software development, such as inheritance, hiding, and polymorphism. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance.

Write the Java code to display the content of the. 2003-2023 Chegg Inc. All rights reserved. The ability to inherit the properties of one class to another, or inherit the properties from a base class to an inherited class is known as the concept of Inheritance. In Python, class form the basis of OOP. Inheritance feature is used for concept of code re-usability as in inheritance a class can inherit properties and functions of existing well written class. The concept of code reusability is based on inheritance, in which a class can inherit the properties and functions of an existing well-written class. It is also taught as a conventional method to write for the most part of a programmers school career. Today, we'll go through the fundamentals and features of OOPS so you can start using it in your projects. Select one: a.Inheritance .xption c.Encapsulation d.Abstraction. Which two features of oops are the same? Which feature in OOP is used to allocate additional function to a predefined operator in any language? These functions are specified inside the class and execute an action beneficial to that particular object type. These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. b) Function overriding Click card to see definition . a) Operator Overloading The following are some of the advantages of encapsulation: Abstraction refers to the users interaction with just a subset of an objects characteristics and operations. Use of the phrase "OO reuse" probably indicates navety. A. Decreases the testing time B. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance. With an object of a class, we can access the data members and member functions that can be accessed (as per the private, public, protected accessibility scope). Here is the real-life example of an object in OOPS is: Class: Human, Object: Man, Woman. Further, it alsoresolves drawbacks of Procedural programming i.e code complexity, unusable code. Which of the following best defines a class? This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on OOP Features. Polymorphism is a term used to describe how a single entity . Its utilized to break down a software program into reusable code blueprints (called classes) that you may use to build specific instances of things. Because Java has four OOPS concepts: inheritance, encapsulation, polymorphism, and abstraction. The above code represents, how a laptops attributes and its behavior are put together in a single place. How many basic features of OOP are required for a programming language to be purely OOP? Keep complicated information hidden from the user. 10. For example, consider an entity Laptop , what attributes, you can think of? Inheritance indicates code reusability, which is a feature of OOPS, whereas all other options do not represent OOPS features. Code reusability is one of the characteristics of object-oriented programming, which is done through the inheritance OOP concept.
