c) Inline function Inheritance: This makes coding more flexible, which tends to lead to better code organization in smaller and simple units. Object-Oriented Security is the practice of using common object-oriented design patterns as a mechanism for access control. The answer to what in OOP produces code reusability is information hiding. 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. Which feature of OOP indicates code reusability? main concept behind inhertience are extensibility and code reuse (in this case you are extending the Employee class and using its code into sub class or derived class).

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. A sign of good code reuse is that one can add a new feature to the code and minimally change the existing code; perhaps in one place or not at all. b) Data Binding Further, it alsoresolves drawbacks of Procedural programming i.e code complexity, unusable code. It is an identifiable entity that can have some descriptive properties. It utilises class hierarchy, including superclasses and subclasses which allow for reusability and the extension of existing classes (Wu, 2010, p. 23). 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..

These functions are specified inside the class and execute an action beneficial to that particular object type. Other objects dont have direct access to this state. OOPs, or Object-oriented programming is an approach or a programming pattern where the programs are structured around objects rather than functions and logic. Classes are organized into hierarchies, and inheritance enables one classs structure and functions to be transferred down the hierarchy. This OOPS feature inherits the features of another class in the programs. But the multiple inheritance can be implemented using interfaces in Java. Its utilized to break down a software program into reusable code blueprints (called classes) that you may use to build specific instances of things. Tap card to see definition . With inheritance, an object can be extended and code from the parent object can be reused or overloaded in the child object. Good point, but I voted 4. Further, one is, object use is must, secondly, message passing and lastly, Dynamic binding. What are the limitations of object-oriented programming?
