Which Feature of OOP illustrated the code reusability? It describes the idea of wrapping data and the methods that work on data within one unit, e.g., a class in Java. 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. You can use it to reuse existing code, design clean APIs, and change the implementation of a class used in a composition without adapting any external clients. For example chair, bike, marker, pen, table, car, etc. The important features which are help to design the object-oriented programming and design is given below: Development over the designed programming paradigm. Code reuse is the practice of using existing code for a new function or software. An object is referred to as a data field that has unique attributes and behavior. For example, Sharon is a programmer who has developed an object for rendering . Sometimes we need to access some part at the runtime if we need then we can use this approach. An object is not considered a standalone program; instead it is the service being used in the programs. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. d) Encapsulation and Inheritance described here along with there mapped relevance with VHDL. -only one allowed -maximum 10 -an optional, Explain how do behavior models differ from Scenario based models? This preview shows page 2 - 5 out of 8 pages. For example, add(20,30) calls the two-parameter add() function, whereas add(10,20,30) calls the three-parameter add method. The term encapsulation (or OOP Encapsulation) is used in object-oriented computer programming languages to refer to the bundling of data and the methods that operate on it into a single unit. a) code reusability b) modularity c) duplicate/redundan Get the answers you need, now!
