OBJECT ORIENTED PROGRAMMING SYSTEM
=================================================
OOPS:- Object Oriented Programming Language
---------------------------------------------------------------
It is very important concept in Java Language. OOPS have three parts based on their process.
a.OOD:-Object Oriented Designing
b.OOA:-Object Oriented Approach
c.OOP:-Object Oriented Programming
The combination of above three parts are called "OOPS".
Above all process is used to develop any application systematically by following set of predefined standards. All the standards comes under "Unified Modiling Language"(UML)
a.Object Oriented Designing(OOD):-
---------------------------------------------
It stands for object oriented design. It determines to develop the application by phasewise designing of each module and each module will be designed later by following set of methods, principles and applications.
b.Object Oriented Approach(OOA):-
----------------------------------------------
It follows the object oriented designing based on its (OOD) phase.
c.Object Oriented Programming(OOP):-
--------------------------------------------------
It determines the real implementation of program(coding) by following set of functions libraries,header files and other technical tools by performing a suitable syntaxes. Any real implementation of the program in OOP which follows a standard structure of program.
In Java we have a standard structure of program. If you write program we should clear about object.
* Standard Structure of Program in OOPS:-
class
Object
objective
1.Data Members
2.Member Functions
Class:-
In a Java program the "class" keyword denotes that the Java program follows this standard of class structure.
(or)
Class is nothing but collection of data and functions.
(or)
Collection of data members and member functions.
2.Objective:-
It is a invisible and it is the end result of an application which can be achieved using data members and member functions. Objective means end result of the programme.
3.Data Members:-
Data members are the elements which can be participated in a prog to achieve the objective of an application.
4.Member Function:-
It is a process of a technic in a program which can take a parameter and returns a value. Member function can be called methods in OOPS Programming.
5.Object:-
It is a instance of a class which can be gives the reference to its. The data member and the member functions which can be used outside of the class.
(or)
Object is nothing but instance of class.
Datatypes:-
Datatypes which are denotes what type of data that your processing to our program.
Variables:-
It is a location memory where we can store the values into the memory those values in the memory called "constants".
OOPS:- Object Oriented Programming System
--------------------------------------------------------------
1.Encapsulation
2.Data Abstraction
3.Polymorphism
4.Inheritance
1.Data Encapsulation:-
The union of data and functions into objects is known as Data Encapsulation.
(or)
Details of what a class contains need not be visible to other classes and objects that use it. Instead, only specific information can be made visible and the others can be hidden. This is achieved through encapsulation, also called data hiding. Both abstraction and encapsulation are complementary to each other.
Data Abstraction:-
-----------------------
We can give restricting the data, to set a number of functions.
(or)
It gives security.
(or)
Abstraction is the feature of extracting only the required information from objects. For example, consider a television as an object. It has a manual stating how to use the television. However, this manual does not show all the technical details of television, thus giving only an abstraction to the user.
Polymorphism:-
-------------------
It is ability to take more than one form.
(or)
Use of something for different purposes.
(or)
Polymorphism is the ability to behave differently in different situations. It is basically seen in programs where you have multiple method declared with the same name but with diferent parameters and different behavior.
Inheritance:-
----------------
Relation between two classes.
(or)
Object of one class can acquire the properties of another class.
(or)
Inheritance is the process of creating a new class based on the attributes and methods of an existing class. The existing class is called the base class whereas the new calss created is called the derived class. This is very important concept of objet-oriented programming as it helps to reuse the inherited attributes and methods.
Super Class:-
---------------
It is a old class or parent class
Sub Class:-
--------------------
It is a new class or child class which can acquire the properties from base class.
