c) Inline function Reusability could be described as creating a new class by reusing the properties of the existing class. Inheritance is the feature of OOPs that describes the reusability of code. Data abstraction is one of the most essential and important feature of object oriented programming in C++. a) Encapsulation b) Inheritance c) Abstraction d) Polymorphism View Answer. Some of the most common OOP concepts in C# are encapsulation, inheritance, and polymorphism. Which operator from the following can be used to illustrate the feature of, 11)In which of the following can we implement polymorphism, 13)which of the following is not a type of Inheritance, 14)Which of the following has a syntax error. Answer: c. Explanation: For the feature given above, the OOP feature used is Polymorphism. Abstraction is selecting data from a larger pool to show only relevant details of the object to the user. Inheritance is relevant due to the concept of Code Reusability. a) Code reusability b) Modularity c) Duplicate/Redundant data d) Efficient Code Answer: c Clarification: Duplicate/Redundant data is dependent on programmer and hence cant be guaranteed by OOP. Home | About | Contact | Copyright | Report Content | Privacy | Cookie Policy | Terms & Conditions | Sitemap. I know that schools ask questions like this and expect you to say inheritance. In procedural programming, a program is divided into various procedures or functions which operate on data, the issue with this approach is, when the program grows larger, the code redundancy, maintainability, and complexity increases. Which language does not support all 4 types of inheritance? Today, we'll go through the fundamentals and features of OOPS so you can start using it in your projects. (a) Polymorphism (b) Abstraction (c) Encapsulation (d) Inheritance. Individual objects are created using class templates as a blueprint. So reusability is a must if you want an maintainable code. An object is referred to as a data field that has unique attributes and behavior. The fundamental purpose of OOP is to connect data and required functions so that no other section of the code may access them. It's a site that collects all the most frequently asked questions and answers, so you don't have to spend hours on searching anywhere else. Principles of Object Oriented Programming. 2. Polymorphism is a term used in software development to describe a variety of techniques employed by programmers to create flexible and reusable software components. It provides the ability to inherit attributes and behaviours from one class to another class. Code reusability 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 OO reuse is much the same as non-OO reuse. The main idea behind Object Oriented Programming is simplicity, code reusability, extendibility, and security. View Answer. 15)ArrayList is a part of which of the following sub packages? Answer (1 of 2): Probably the person asking this question wants to hear that it is a class inheritance or some other specific feature of object-oriented language the produces reused code. The general reason why Java is considered to be more secure than, say C, is because it handles memory management for you. 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. Reduces the compilation time C. Lowers the maintenance cost D. Both A and C. View Answer (c) Reusability is the main feature It helps in reducing the complexity of writing very large codes as it provides the code reuse feature. 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. Question 38: Answer:Inheritance Explanation: The reusability of code is possible using inheritance. LIVE Course for free. Object-Oriented Programming (OOP) was coined by Alan Kay circa 1966 or 1967 while he was at grad school. Importance on data rather than algorithms. To provide the feature of data hiding that is good for security concerns. Overview of OOP in Java. Question 38 (2 points) Which Feature of OOP boost the code reusability? Grasping OOP concepts is key to understanding how Java works. Object-Oriented programming focuses on binding attributes and behavior of a real-world entity represented using an object and supports features like abstraction, encapsulation, inheritance, and polymorphism. Because Java compiles as bytecode which then runs inside a Virtual machine, it cannot access the computer it runs on like a natively compiled program can. Encapsulation can manage accessibility and hide the attributes and behaviour of an object. Sort the Array in Ascending order (default). Polymorphism refers to the ability of a programming language to provide the same interface for a variety of underlying data types. Reusability: Inheritance supports the concept of reusability, i.e. This is the definition of abstraction. Explanation: Java does not support all four types of inheritance. Encapsulation is one of the fundamentals of OOP (object-oriented programming). Inheritance if the feature of OOP that indicates the reusability of a code, the features which are encapsulation and abstraction serves the purpose of hiding or grouping data in a single element. Which of the statements are true about OOP Paradigm? 16. Kindly, choose the right option for every question to check your final preparation. View Answer, 2. Question 2. Classes are organized into hierarchies, and inheritance enables one classs structure and functions to be transferred down the hierarchy. It simplifies the process of seeing things in their entirety. c) It depends on type of program RiSE: a . For example, MyCar and goldenRetriever are two particular instances of the abstract class. A class is like a blueprint for creating objects. One of the most practical examples of encapsulation is a school bag. a) Instance of a class b) Instance of itself c) Child of a class d) Overview of a class 5. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. Java programming is an object-oriented language that can be used to design the objects and to reuse the codes as and when required. Consider the following scenario: you wish to store two numbers for the same individual in an object-oriented language such as Java. 11. a) Abstraction b) Encapsulation c) Polymorphism d) Inheritance* 10) Which operator from the following can be used to illustrate the feature of polymorphism? 3. Modularity is the process of decomposing a problem (program) into a set of modules so as to reduce the overall complexity of the problem. It combines a group of related attributes and behaviour within a single unit named class, that enhances program design structure and code readability. On the other hand, other kinds of members, especially methods, allow the behavior of class instances. An object can be defined as an instance of a class, and there can be multiple instances of a class in a program. Code Reuse: Functions and Modules Reusing code is key to building a maintainable system. Reusability in OOP is achieved by using C++ features that allow you to extend or reuse parent, super class, or base class properties in a subclass, as well as adding additional features or data members to the subclass, child class, or derived class. See 10 tips on writing reusable code for some help. a) 7 Code reuse is the use of existing software to build new software. OOps in java is to improve code readability and reusability by defining a Java program efficiently. Objects have their own properties and behavior. Polymorphism is to indicate different tasks performed by a single entity. -only one allowed -maximum 10 -an optional, Explain how do behavior models differ from Scenario based models? b) Inheritance. Data hiding is a characteristic of object-oriented programming . If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? Object Oriented Programming (OOP) is based on the concept of objects rather than actions, and data rather than logic. Inheritance -. It has the capability of storing your Contacts. Exception Handling & Static Class Members, Assigning Object, Passing & Returning Object, Default Arguments, Upcasting & Downcasting, here is complete set of 1000+ Multiple Choice Questions and Answers, Prev - Object Oriented Programming using C++ Questions and Answers Objects, Next - Object Oriented Programming using C++ Questions and Answers Polymorphism, Certificate of Merit in Object Oriented Programming, Object Oriented Programming Certification Contest, Top Ranker in Object Oriented Programming, Object Oriented Programming using C++ Questions and Answers OOPs Basic Concepts, C++ Programming Questions and Answers OOPs Concept 1, Object Oriented System Design Questions and Answers Programming Principles, Object Oriented Programming using C++ Questions and Answers Encapsulation, Object Oriented Programming using C++ Questions and Answers Derived Class, Object Oriented Programming using C++ Questions and Answers Overriding Member Functions, Object Oriented Programming using C++ Questions and Answers Abstraction, Java Questions & Answers Concepts of OOPs, Object Oriented Programming using C++ Questions and Answers Multilevel Inheritance, Object Oriented System Design Questions and Answers Foundations of Object Model 1, Object Oriented Programming MCQ Questions, Object Oriented Programming Certification. Inheritance allows, code reusability and the polymorphism is, the occurrence of one function with different form. OOP is a striking shift from LP. Programmers can then establish procedural code that governs data accessibility and makes it easy to add new functionality as applications and software architectures evolve over time. You may do this by storing the second number under the same name as the first. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security. For a language to be classified as OOP, it must have these 4 OOP blocks. c) Abstraction. Q5. It is based on the concepts of objects and classes, which bundle together properties (data members) and behaviours (member methods). Which Feature of OOP illustrated the code reusability? In C++ program if we implement class with private and public members then it is an example of data abstraction. 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. The main principles of object-oriented programming are abstraction, encapsulation, inheritance, and polymorphism. b. Inheritance. Because Java has four OOPS concepts: inheritance, encapsulation, polymorphism, and abstraction. Java OOP. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function. It enables code reusability by allowing a new class. Q1: Which are the best features of OOPs, and why explain?Ans: Encapsulation, inheritance, and polymorphism are three fundamental elements of object-oriented programming that distinguish it from non-OOP languages. Which Feature of OOP illustrated the code reusability? "Start Class" is not type of class true or false? Which feature in OOP is used to allocate additional function to a predefined operator in any language? Exception handling is a feature of OOP. All Rights Reserved. The above code represents, how a laptops attributes and its behavior are put together in a single place. Inheritance indicates code reusability, which is a feature of OOPS, whereas all other options do not represent OOPS features. Inheritance is a feature by which a class acquires attributes of another class. Both procedural and object-oriented are imperative programming. Which Oops is accepted to reuse the code? What is the Samsung TV code for DISH Network remote. apart . Code Reusability : The existing code in object oriented programming can be reused by the feature referred to as inheritance. A child class can access and use methods and fields of the parent class which leads to code reusability. It is like a blueprint of an object. List of Java OOPs Concepts. Abstraction in header files: An another type of abstraction is header file. Hence, it can be used to bundle the functions and data but not for code reusability. Authors of new programs can use the code in a software library to perform these tasks, instead of re-inventing the wheel, by writing fully new code directly in a program to perform an operation. Q) Which C++ oops feature is related to re-usability? Here is the real-life example of an object in OOPS is: Class: Human, Object: Man, Woman. There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . Q) What C++ oops feature has something to do with reusability? The attributes specified in the class may have unique values for each object. Code for an extension. Which feature of oops is described as the reusability of code? 9) Which feature of OOPS described the reusability of code? Reusability of the code can be achieved in CPP through inheritance. Polymorphism: An important feature of object-oriented programming that allows programmers to write programs that are easier for other projects to create and reuse. Inheritance: Inheritance is an important pillar of OOP(Object-Oriented Programming). 1. A variable, function, or data structure may all be considered an object. 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). Explanation: OOP does not have platform independence. Which among the following, for a pure OOP language, is true? This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on OOP Features. Ivan Sutherlands seminal Sketchpad application was an early inspiration for OOP. When you inherit from an existing class, you can reuse methods and fields of the parent class. Inheritance. 4. a) The private members cant be accessed by public members of the class, b) The private members can be accessed by public members of the class*, c) The private members can be accessed only by the private members of the class, d) The private members cant be accessed by the protected members of the class. One of the advantages of using Object Oriented Programming is for code reuse, which can be achieved by two ways; either inheritance or composition. d) Inheritance is a feature of OOP that allows a class to inherit the properties and methods of another class. Which is not feature of OOP in general definitions? Only the methods that are elements of a similar class only can access private members. When it comes to solving the problem of code/data separation, the use of Object -Oriented Programming has played a big role in the rising of object reusability. EMMY NOMINATIONS 2022: Outstanding Limited Or Anthology Series, EMMY NOMINATIONS 2022: Outstanding Lead Actress In A Comedy Series, EMMY NOMINATIONS 2022: Outstanding Supporting Actor In A Comedy Series, EMMY NOMINATIONS 2022: Outstanding Lead Actress In A Limited Or Anthology Series Or Movie, EMMY NOMINATIONS 2022: Outstanding Lead Actor In A Limited Or Anthology Series Or Movie. A program written within the Object-Oriented Programming approach will have reusable blocks of codes termed classes. These functions are specified inside the class and execute an action beneficial to that particular object type. Object Oriented Programming Objective type Questions and Answers. 23) also identifies another mechanism in object-oriented programming called inheritance, which he says is used to design two or more entities that are different but share many common features. This preview shows page 2 - 5 out of 8 pages. 10. 16. Notify me of follow-up comments by email. Therefore, depending on the number of parameters entered, you may obtain different results. The father, on the other hand, is right-handed, while the kid is left-handed. A. Decreases the testing time B. Simple items are used to show complexity. Prototyping is another name for inheritance in JavaScript. The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. The important features which are help to design the object-oriented programming and design is given below: Development over the designed programming paradigm. Which of the following does not fall under the OOP concept? Conclusion. Which feature of OOP is indicated by the following code? For example, if the file name is prime.py, the module name is prime. 2003-2023 Chegg Inc. All rights reserved. APIs provide a mechanism to enable code reuse. Encapsulation is intrinsically linked to modularity. Using OOP, we can resemble our code in the real world. Parent classes, in other words, extend properties and behaviors to child classes. The object-oriented programming approach allows developers to bind and manipulate data using exclusive functions.These functions cover a range of operations, including code reuse and variable designation. The opposite concept of reusability . View Answer, 4. This promise is predicated on the assertion that if you build generic objects they can be used and reused. A Classname obj = new() Classname() B Classname obj = new Classname; Instance of a class. Characteristics of Object Oriented Languages. Using inheritance we can reuse the code already written and also can avoid creation of many new functions or variables, as that can be done one time and be reused . 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. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. View Answer, 5. It was designed to improve upon existing concepts in C. C# powers the Microsoft .NET framework alongside many web apps, games, desktop apps, and mobile apps. Simple classes are used to indicate complexity in abstraction. Systematically developing high-quality reusable software components and . First of all, OOP way of code reuse is not the myth at all; the problem is different. 12. Object-oriented programming (OOP) is the most prevalent programming paradigm. Which of the following is not a feature of pure OOP? OOP is supported by C, but it is not a platform-dependent language. This OOPS feature inherits the features of another class in the programs. In 3 simple steps you can find your personalised career roadmap in Software development for FREE, Difference Between Product and Service Based Company. For defining modules, Booch sets two goals. a) Encapsulation b) Inheritance c) Polymorphism d) Abstraction 6. Which is not feature of OOP in general definitions? Constructors in most object-oriented languages have the same name as the class and are public. which feature of oops described the reusability of code? Which is most appropriate comment on following class definition? OOP concepts (OOP) intend to improve code readability and reusability by defining how to structure a Java program efficiently. However, the advantages of object-oriented programming are many. The answer to what in OOP produces code reusability is information hiding. This mechanism actually inherits the fields and methods of the superclass. b) 6 View Answer, 14. Object-oriented programming (OOP) refers to a programming methodology based on objects, instead of just functions and procedures as in functional programming. The fundamental purpose of OOP is to connect data and required functions so that no other section of the code may access them. It offers features like abstraction, encapsulation, modularity, inheritance, and polymorphism.
