ABSTRUCTION:
Process of providing the neccesary properties & operations
of an object is called as abstuction
Example take car the car user only know things reqired.
he don't no the internal functionality of the car b'coz it
is not required for the user .
properties like car:colour,number,model etc.
operations like car:move front,backetc.
ENCAPSULATION:
Process of providing all the properties&operayion of entity
in one place is called as encapsulation.
In java operations are called as methods,properties are
called as variables.
The place where you were write the variables &properties is
called as class.

Answer / narender_niit
abstraction:
abstraction means providing the relevant information only
and hiding other information..
encapsulation:
encapsulation means capsuling of data in the class..in
encapsulation the data members are declared in a class.and
we u want to use that variables only the copy of the
variables goes there which we use in other public
classes.this generates the concept of information hiding.
encapsulation also provide scurity to the data variables

Answer / b.vara lakshmi
abstaction means hiding information details.it creates a
new data item with encapsulated objects.
encapusulation means it encapsulates both the code and data
and it manipulates the both and keeps safe from
interferences and misuse.

Answer / sdk
Encapsulation prevents the code and data of one class to be
accessed by code which is out side class
Abstraction refers to hiding of irrelevant data.

Answer / vikas
In C++ terms, abstraction is achieved by access modifiers:
private and protected. Encapsulation is achieved by classes

Answer / ganesh
ABSTRACTION
An abstract class is a parent class that allows inheritance
but can never be instantiated. Abstract classes contain one
or more abstract methods that do not have implementation.
Abstract classes allow specialization of inherited classes.
ENCAPSULATION:
Wrapping up of data into a single unit..

Can destructor be overloaded?
what is the abstract class,interface ,its difference with a programatic eg.? hi,recently i went for an interview they ask me what is abstract class ,interface and its difference I said abstract class contain abstact method ,abstract method is a method with no body.Abstract class cannot be instantiated.Abstract class is a base class it required derived class for the implementation of method. Interface is a syntactical contract that all derived class should follow it define properties ,method,events which are known as member of interface. Then They asked me what is the difference between them. I said abstract class interface 1.abstact class can implement method 1.interface cant 2.abstact class can contain constructor, 2.interface cant destructor 3.abstract class cannot support multiple 3.interface support inheritance etc Then they said some different answer I said dont no. Then they ask me when i should make abstract class for an project and when i should make interface. I said if suppose there is two class which must be having method with different logic then we sholud make abstract class. and if suppose we have two class having method .with different logic then we can make interface . Am i correct with my explaination.if not correct me .please provide me that when should we create abstract class and interface and what is difference .please help me
