A module in Python is nothing but a file containing Python definitions followed by methods & statements. Object-oriented programming (OOP) refers to a programming methodology based on objects, instead of just functions and procedures as in functional programming. This means we can add new features to an existing class without having to modify it. The purpose of encapsulation and abstraction is to hide/group data into a single unit. The main ideas behind Java's Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism. 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. View Answer.

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. private (or class-private) specifiers restrict the entrance to the class itself. As hardware and software became increasingly complex, manageability often became a concern. One of the most important and essential features of object-oriented programming in C is data abstraction. 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 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. But OOP has been very criticized for its reduced reusability. When you inherit from an existing class, you can reuse methods and fields of the parent class.

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. A program written within the Object-Oriented Programming approach will have reusable blocks of codes termed classes. For a language to be classified as OOP, it must have these 4 OOP blocks. The in-depthtopic of Polymorphism will be discussed in later articles. Polymorphism is a feature of OOP that serves the purpose of indicating different tasks that are carried out a one entity. .
