What are the OOPS concepts?..

Answer / swetcha

1) Encapsulation: It is the mechanism that binds together
code and data in manipulates, and keeps both safe from
outside interference and misuse. In short it isolates a
particular code and data from all other codes and data. A
well-defined interface controls the access to that
particular code and data.
2) Inheritance: It is the process by which one object
acquires the properties of another object. This supports
the hierarchical classification. Without the use of
hierarchies, each object would need to define all its
characteristics explicitly. However, by use of inheritance,
an object need only define those qualities that make it
unique within its class. It can inherit its general
attributes from its parent. A new sub-class inherits all of
the attributes of all of its ancestors.
3) Polymorphism: It is a feature that allows one interface
to be used for general class of actions. The specific
action is determined by the exact nature of the situation.
In general polymorphism means "one interface, multiple
methods", This means that it is possible to design a
generic interface to a group of related activities. This
helps reduce complexity by allowing the same interface to
be used to specify a general class of action. It is the
compiler's job to select the specific action (that is,
method) as it applies to each situation

Answer / manila

BASIC CONCEPT OF OOPS:
1.OBJECTS:
An object is an abstraction of a real world entity. It may
represent a person,a placea number and icons or something
else that can be modelled.Any data in an object occupy some
space in memory and can communicate with eachother .
2.CLASSES:
A class is a collection of objects having common
features .It is a user defined datatypes which has data
members as well functions that manupulate these datas.
3.ABSTRACTION:
It can be definr\ed as the seperation of unnecessary
details or explation from system requirments so as to
reduce the complaxities of understanding requirments.
4.ENCAPTULATION:
It is a mechanism that puts the data and function together.
It is bthe result of hiding implimintation details of an
object from its user .The object hides its data to de
accessed by only those functions which are packed in the
class of that object.
5.INHERITANCE:
It is the relationship between two classes of object such
that one of the classes ,the child takes all the relevent
features of other class -the parent.
Inheritance bring about reusablity.
6.POLYMORPHISM:
polymorphism means having many forms that in a single
entity can takes more than one form.Polymorphism is
implemented through operator overloading and function
overloading.
7.DYNAMIC BINDING:
Dynamic binding is the proces of resolving the function to
be associated with yhe respective functions calls during
their runtime rather than compile time.
8.MESSAGE PASSING:
Every data in an objest in oops that is capable of
processing request known as message .All object can
communicate with each other by sending message to each other

Answer / janet

Object oriented programming organizes a program around it's
data i.e objects and a set of well defined interface to
that data. An Object-oriented program can be characterized
as data controlling access to code.
