It combines a group of related attributes and behaviour within a single unit named class, that enhances program design structure and code readability. Use of the phrase "OO reuse" probably indicates navety. For example, code inside the class template defines attributes and behaviors. Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. Object-oriented programming combines a group of variables (properties) and functions (methods) into a unit called an "object." For example, if the file name is prime.py, the module name is prime. Further, object use is required, message passing is required, and finally dynamic binding is required. It provides the ability to inherit attributes and behaviours from one class to another class. The fundamental purpose of OOP is to connect data and required functions so that no other section of the code may access them. One of the most practical examples of encapsulation is a school bag. The power of object-oriented systems lies in their promise of code reuse. Objects in object-oriented programming are answers to the idea of inheritance, resulting in improved program dependability, simpler software maintenance, library administration, and task division in programmer teams. Object-oriented programming (OOP) is the most prevalent programming paradigm. Were expected to make two distinct sorts of polygons: a Rectangle and a Triangle. 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:-. protected (or class-protected) specifies enables the class itself and all classes under it (sub-classes) to access the member and public means that member can be accessed by its name using any code. These functions are specified inside the class and execute an action beneficial to that particular object type. This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods). 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. Does OOP provide better security than POP? Thus, you may use multiple prototype object templates to form a prototype chain. The object-oriented programming is basically a computer programming design philosophy or methodology that organizes/ models software design around data, or objects rather than functions and logic. Observer b. Inside a class, encapsulation conceals the underlying software code implementation and the internal data of the objects.

The data and methods are then enclosed in the object when it is created from the class. c) The language must follow only 3 features of OOP Consider the following scenario: you wish to store two numbers for the same individual in an object-oriented language such as Java. This concept is often used to hide the internal state representation of an object from the outside. Does OOP provide better security than POP. A very common example of code reuse is the technique of using a software library. d) Abstraction Inheritance is passed down from one generation to the next. Object can't be used with pointers because they belong to user defined class, and compiler can't decide the type of data may be used inside the class. Reusability: Object Oriented Programming - 584 Words | Studymode That does not imply that it is of poor quality. A child class can access and use methods and fields of the parent class which leads to code reusability. Encapsulation is the process of enclosing all critical information inside an object and only revealing a subset of it to the outside world. Specifically, the right hand. Many latest languages are using OOPS concept as it is highly secure. Which of the following is not a feature of pure OOP? View Answer, 11.
