The basic Object-oriented programming concepts are: Inheritance. Inheritance can be defined as the process where one (parent/super) class acquires the properties (methods and fields) of another (child/sub). With the use of inheritance, the information is made manageable in a hierarchical order. Object-oriented programming has only come into fashion in the 1990's. This module is broken down into three sections. First, you will find a high-level overview that shows object-oriented programming to be a very natural concept since it mirrors how your hunter-gatherer mind views the outside world. Pure Object-Oriented Languages. Five rules Source: Alan Kay:.Everything in an object.A program is a set of objects telling each other what to do by sending messages.Each object has its own memory (made up by other objects).Every object has a type.All objects of a specific type can receive the same messages.

Visual Basic.Net 4 1.4. A Brief Look at Object-Oriented Programming (OOP) Since Visual Basic was first introduced in the early 1990’s, a major criticism from many programmers (especially those using C and C) was that it was not a true object-oriented language. And, with that limitation, many dismissed Visual Basic as a “toy” language. Object Oriented programming is a programming style that is associated with the concept of Class, Objects and various other concepts revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc. OOPS is abbreviated as Object Oriented Programming system in which programs are considered as a collection of objects. Each object is nothing but an instance of a class. 2) Write basic concepts of OOPS?
Inheritance
Inheritance can be defined as the process where one (parent/super) class acquires the properties (methods and fields) of another (child/sub). With the use of inheritance, the information is made manageable in a hierarchical order.
Polymorphism
Polymorphism is the ability of an object to perform different actions (or, exhibit different behaviors) based on the context.
Abstraction
Abstraction is a process of hiding the implementation details from the user, only the functionality will be provided to the user. In other words, the user will have the information on what the object does instead of how it does it.
In Java, abstraction is achieved using Abstract classes and interfaces.
Encapsulation
Encapsulation in Java is a mechanism for wrapping the data (variables) and code acting on the data (methods) together as a single unit. In encapsulation, the variables of a class will be hidden from other classes and can be accessed only through the methods of their current class. Therefore, it is also known as data hiding. To achieve encapsulation in Java −
- Declare the variables of a class as private.
- Provide public setter and getter methods to modify and view the variables values.
