Answer Posted / nagur dethri
in java there are four main concepts which are back_bone to
java,they are.
ABSTRACTION,
ENCAPSULATION,
INHERITANCE,
POLYMORPHISM.
ABSTRACTION:Simply,abstraction means showing
essentialthings and hiding non_essential or un_neccessary
things.
Eg:many people want to drive different types of cars with
variety styles.here,we are hiding the inner side design
(i.eengine battery,sound system wirings etc.,i.e
non_essential)but we are showing (sound system,remote
system to operate those systems).
ENCAPSULATION:combing of both data and methods.
eg:simply in java language,in an single class we are using
or combing both instance variables and methods.
POLYMORPHISM:it is an ability to take more than one form.
eg:STUDENT,a student is acting like a student in college
camplus,and also acting as an employee in part time job and
acting as an daughter/son in homes.
INHERITANCE:in java,deriving a new class from an old class
(i.e,already existing one) or simply new or derived or
super class acquiring the properties of old class or base
or sub class.
eg:as_usual,CHILD AND PARENT RELATIONSHIP i.e,jeans
(daughter or son getting the fetures of his/her parents).
THANK YOU.
