OOPS concepts implementation

You can find many tutorials on internet to start with oops.

 

Object oriented programming (OOP) is a programming structure where programs are organized around objects as opposed to action and logic. This is essentially a design philosophy that uses a different set of programming languages such as C#. Understanding OOP concepts can help make decisions about how you should design an application and what language to use.

 

What is an Object?

Objects are instances of classes. In other words, an instance of a class is an object defined by that particular class. Creating a new instance, or an object, is called instantiation. This is how you define a class:

 

A light version of classes in C# is called structures. These are beneficial when you want to create a large array of objects but don’t want to overwhelm your available memory. A class is made up of three things:

 

A name

Operations

Attributes

 

In memory, you can create an object using the “new” keyword. In C#, value types refer to other data type variables while objects are reference types. Moreover, other value types are stored in the stack while objects are stored in the heap.

 

Keep in mind that everything in C# is a class. An object is a section of memory that has been configured according to the class blueprint. Every instance, or object, of a particular class has access to several methods and properties of that class.

 

Data Abstraction

This provides essential features without describing any background details. Abstraction is important because it can hide unnecessary details from reference objects to names. It is also necessary for the construction of programs. Instead of showing how an object is represented or how it works, it focuses on what an object does. Therefore, data abstraction is often used for managing large and complex programs.

 

Encapsulation

This binds the member function and data member into a single class. This also allows for abstraction. Within OOP, encapsulation can be achieved through creating classes. Those classes then display public methods and properties. The name encapsulation comes from the fact that this class encapsulates the set of methods, properties, and attributes of its functionalities to other classes.

 

Polymorphism

This is the ability of an object to perform in a wide variety of ways. There are two types:

1. Dynamic polymorphism (runtime time). You can obtain this type through executing function overriding.

2. Static polymorphism (compile time). You can achieve static polymorphism through function overloading and operator overloading.

 

Within OOP, polymorphism can be achieved using many techniques including:

Method overloading (defining several methods at the same time)

 

Method overriding (this allows a subclass to override a specific implementation of a method already issued by one of its super-classes)

 

Operator overloading (some or all of the operators are handled has polymorphic functions with different behaviors depending on the types of its arguments)

 

Inheritance

Through inheritance, a class can “inherit” the characteristics of another general class. To illustrate, dogs are believed to be the descendants of wolves. All dogs have four paws and can hunt their prey. This function can be coded into the Wolf class. All of its descendants can use it. Inheritance is also an is-kind-of relationship. For instance, a golden retriever is a kind of animal.
