Oops Concepts in C#

Hi,

 

one way to implement abstraction is Abstract Classes.

And dont get confuse in Inheritance and abstraction because:

 Reason being both use for different purpose in C#.

Abstraction is being used to show what actualy is being needed(not everthing) and Inheritance in use the what actually is there. 

Hi,

 

The best article on OOPs is here... this will clear your all doubts.

Hope this will also help you.

thanks 

Hi,

"Abstract" is an antonym of "concrete". With abstractions you represent notions and ideas, rather than the concrete way these ideas are implemented. This fits into your understanding of abstraction - you are hiding the details and you only show the interface.

Example:

abstract class CurryBase
{
public abstract void doCurryMasala();
}

public class FishCurry : CurryBase
{
public void doCurryMasala()
{
// Add Fish Curry specific contents also.
}
}

Are you sure,

Unlike an Interface it can contain concrete things and in this case it is even very hot.

 abstract class CurryBase { public void doCurryMasala(); public double Peper {get;set;} } public class FishCurry : CurryBase { public void doCurryMasala() { // Add Fish Curry specific contents also. } }

 Hope this will help you.

1. Abstract clsss is not equal to Abstraction of OOD principle

 

Abasction is about providing abstract view about class and not to provide detail abou it.

 

Example of is Car : in car you know how to  shift gear in car but you dont know what is going in detail how gear system works.

Same gose for car engine. in that you know about engine but you dont get details of how enging work in detail like how it works. same in class you have like this 

 

public class car 

{

  public bool shiftGear

  {

    //details of shifing gear

  } 

}

 

class using car class know method shiftGear but not aware about detail.

 

public class usecar

{

   public void usershiftgear

   { 

      car c = new car();

      c.shiftGear();

   }

}

 

 

2. Abstracion vs inheritance - I hope from above example you get what abastraction is.

 

So Abstraction is not similar to inheritance.

as inheritace deals with relationship between classes and abstraction deals with hiding detail, provide abstract view.

 

3. Inheritance - 

One can not use inheritance for just for reusability. But inheritance is used for showing relationship between objects also.

 

As OOD is about converting real time object in the programming object. Inheritace is used for showing that relationship between that object.

 

Example is person.

In real world as person can be teacher, a employee, a devloper , an manager.

 

 so in ood to show this relation we use inheritace to show this parent child relation like person is parent and than we have child of person employee, teacher, developer, manager.

 

and when you are inheriting person class, that also means we are going to reuse properties of it in the child , so there is no meaning of defining this property.

 

because of Inheritance  we have one more principle of OOD Polymorphism , which lead you to overloading and overriding - using same name for different purpose.
