Answer / mms zubeir

As I answered one of the questions here, the abstraction is
nothing but declaration of a concept in software terms
which does not exist in real-world.

For example, mango, drumstick, brinjal, potato are all
vegetables. But "Vegetable" is just a concept and it has no
real-world existance.

To represent these kind of concept in software terms, we
need abstration.

On the other hand, the mango, brinjal, ... are all have
concrete implementations since they have certain properties
and can do some operations on them in the real world.

I couldn't get the third question "abstraction for stack",
but I try to answer with what I understood.

Normally, stack's operations include push, pop, top, size,
empty e.t.c. If we define an interface with these, it ll be
an abstraction for stack. Let me know if it doesn't answer
your question.

Abstraction literally means hiding. Now in OOP the
intention is to hide the complexity. For this reason
generally the data in classes is protected. THis data is
accessible to the functions(some times called behaviour).
OK! now for a user creating an application, it is easier to
use functions using the objects of class rather than
manipulating the data itself. This is how abstraction
works. Abstraction is a conceptual theory or a way of doing
things, not a must.

Answer / rama

Abstraction refers to the act of representing essential features without including the background details or explanation. Classes use the concept of abstraction and are defined as a list of abstract attributes such as size,weight,and cost, and function to operate on these attributes.

of complex system. that is abstraction is a process to
break the complex system in to small manageble parts.

It is use full in coding.

Answer / ranjit

for the user simplicity .with knowing the internal
details we can use the pakages.in the oops interfaces are
created .with knowing the internal procedure we can use the
interface.
in the large projects in the organization .the team
lader gives the interfaces to the project members they can
impliment that interfaces packages .

ex:-all packages in windows like summation in word pad.

the machanism in stack is "first in last out".
the processes which comes first that will be exicuted last.

Answer / vara prasad

Abstraction is nothing but binding the code and data
together to protect the code and data from out side world.
