OOPS concepts

Question

Dear Sir, I want know understand oops concepts please give me simple examples Abstraction,Encapsulation,Inheritance and polymorbism explain

Anuja Pawar · Answer

Encapsulation: When ever you demand for a task, and you don't know how that task will be done, but you get the result. That is Encapsulation. Encapsulation is nothing but showing only those things which are required by wrapping up complexities. Ex: You order for Orange juice, you don't know the process behind how the juice will be made, ingredients and all other. What you know is the final result. So in simple language hiding of information is Encapsulation. Abstraction: Abstraction is a way to remove the association of the behavior of an object with the actual details behind the scenes which implement that object's behavior. Ex: we invented many things but the actual reason behind them is not known, they are hiding and what we see is the actual thing. Polymorphism: A single function that has different character in different place. As poly means many. Read a very good example Say a door a door to a temple, a door to a house, a door to a kitty house, all are doors but all look different Inheritance: As the word suggest, inheriting from the existing class. We all are human, then human is the base class and we all have 2 hands, 2 legs the properties inheriting from the base class.

Boys use d word "FRIENDSHIP" 2 start LOVE Girls use same word to end LOVE.. "Same word but diferent behaviour" This is known as 'POLYMORPHISM' :-)

Hi For Abstraction and Inheritance refer below link:- http://www.c-sharpcorner.com/Forums/Thread/148684/abstract-class-and-inheritance.aspx For Encapsulation refer below link:- http://dotnetslackers.com/articles/csharp/PolymorphismEncapsulation.aspx Polymorphism:- Q. What is Polymorphism? Polymorphism means same operation may behave differently on different classes. Example of Compile Time Polymorphism: Method Overloading Example of Run Time Polymorphism: Method Overriding Example of Compile Time Polymorphism Method Overloading - Method with same name but with different arguments is called method overloading. - Method Overloading forms compile-time polymorphism. - Example of Method Overloading: class A1 { void hello() { Console.WriteLine("Hello"); } void hello(string s) { Console.WriteLine("Hello {0}",s); } } Example of Run Time Polymorphism Method Overriding - Method overriding occurs when child class declares a method that has the same type arguments as a method declared by one of its superclass. - Method overriding forms Run-time polymorphism. - Note: By default functions are not virtual in C# and so you need to write "virtual" explicitly. While by default in Java each function are virtual. - Example of Method Overriding: Class parent { virtual void hello() { Console.WriteLine("Hello from Parent"); } } Class child : parent { override void hello() { Console.WriteLine("Hello from Child"); } } static void main() { parent objParent = new child(); objParent.hello(); } //Output Hello from Child.

Yes Sam, even i took part in the discussion what is "s" in OOPs. And found t his as an endless discussion, as many will support 1. system 2. structure. 3. indicate a plural but yes i will go with "Object Oriented Programming System" As a system may be based on objects or procedures.

Sam Hobbs · Answer

I never have gotten an answer to the question why "OOP S " with the "s". I think you should look for articles about OOP but not OOPS.

The first two articles in our recommended articles section (see sidebar to right) are about as good as it gets for explaining these concepts. Unfortunately, the third article in the series doesn't appear to have materialized.
