OOPs is Object Oriented Programming.The great thing about OOPs is that is all about classes and objects which can easily correlated with real life scenarios.

Class is the general thing and object is the specilisation of general thing

For example if Human can be a class and linto ,raj etc are names of persons which can be considered as object.It supports concepts such as data abstation,inheritence ,polymorhpism etc.

Data Abstration is the  process of encapsulating data with in object so as to protect data and to avoid unwanted access(You know now the age of information explosion ,so giving proper data has greater significance)

So for our example every human has eye ,so eyecolor can be considered as the property of human being which can be encapsulted as a data in our class Human

class Human

{

private:

EyeColor IColor;

NAME personname;

};

Consider object of class of

Human myhuman;

we want set myhuman's name as "linto" and IColor as "black"

For that we want methods to do that task.

So need methods for class to do a particular task on the data

class Human

{

private:

EyeColor IColor;

NAME personname;

public:

void SetName(NAME anyName);

void SetIColor(EyeColor eyecolor);

};

So a class is a thing which has data members(normally properties of object) and methods to manipulate that data.But the thing to undersand is that class has propeties not any particular data.In other words the Human class no specific IColor.Only when one object of that class (myhuman) has name "linto" and IColor "black".

Next we can go through the concept of inheritence which has the same as the word meaning as u all aware.

           Human

             |

       ____|_____

       |              |

      /              /

   Men            Women

Here Human is general class and Man and Women are sub classes of general thing.That is Human  class contains all features general and Human and Women contains features specific to their own class.

Hey try to write class ...you will get the essence of OOPs.

Abstraction means giving usefull information , encapsulation means hiding unecessary information.

encapsulation

class person
{
private String name;
public void main()
{
System.out.println(""+name);

}
}

Answer Question  Select Best Answer

Abstraction is defined as hiding details from the end user who should be in no way concerned about the details of the internal mechanism on implementation...but then the same can be achieved in C also , i can use functions, and can comfortably be unaware of theinternal complications of the same, so can i say C also supports abstraction??
