Basic concepts of object oriented programming

To read about Polmorphism in detail click the following link: Abstraction solves the problem at the design level. Encapsulation solves the problem in the implementation level. Abstraction hides unwanted data and provides relevant data.

Basic concepts of object oriented programming

The core of the pure object-oriented programming is to create an object, in code, that has certain properties and methods. For example a car is an object which has certain properties such as color, number of doors, and the like.

It also has certain methods such as accelerate, brake, and so on. That is both data and function that operate on data are bundled as a unit called as object. Class When you define a class, you define a blueprint for an object.

This doesn't actually define any data, but it does define what the class name means, that is, what an object of the class will consist of and what operations can be performed on such an object. Abstraction Data abstraction refers to, providing only essential information to the outside world and hiding their background details, i.

For example, a database system hides certain details of how data is stored and created and maintained. Encapsulation Encapsulation is placing the data and the functions that work on that data in the same place.

While working with procedural languages, it is not always clear which functions work on which variables but object-oriented programming provides you framework to place the data and the relevant functions together in the same object. Inheritance One of the most useful aspects of object-oriented programming is code reusability.

As the name suggests Inheritance is the process of forming a new class from an existing class that is from the existing class called as base class, new class is formed called as derived class.

This is a very important concept of object-oriented programming since this feature helps to reduce the code size. Polymorphism The ability to use an operator or function in different ways in other words giving different meaning or functions to the operators or functions is called polymorphism.

Poly refers to many. That is a single function or an operator functioning in many ways different upon the usage is called polymorphism. Overloading The concept of overloading is also a branch of polymorphism.

When the exiting operator or function is made to operate on new data type, it is said to be overloaded.Object Oriented Programming (OOP) is a programming model where programs are organized around objects and data rather than action and logic.

OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. Lesson: Object-Oriented Programming Concepts If you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code.

This lesson will introduce you to objects, classes, inheritance, interfaces, and packages. Visual Basic provides full support for object-oriented programming including encapsulation, inheritance, and polymorphism.

Encapsulation means that a group of related properties, methods, and other members are treated as a single unit or object.

Object Oriented Programming (OOP) is a programming paradigm that is based on the concept of objects. An object is a data structure that . Object Oriented Programming (OOP) is a programming model where programs are organized around objects and data rather than action and logic.

OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. Grasping them is key to understanding how Java works. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.

List of OOP Concepts in Java. There are four main OOP concepts in Java. These are: Abstraction.
