Small concept about OOPs

Some small concept about OOPs:-In many books and website write about OOPs concepts as hundred percent object oriented, pure object oriented and partial object oriented language.

Hundred percent object oriented:-In the hundred percent object oriented movie hero is object, without object program is incomplete that means can not execute program without object. Without class and object programming or application development is not possible.

Example of hundred percent object oriented language is Smalltalk.

Pure object oriented:-In the object oriented cinema obviously object is the hero. In pure object oriented language object having same importance but in this having some relax that is without creating object we can successfully execute our application. So in the object oriented programming without class we cannot create or run our application, class is must.

Example of pure object oriented language is Java.

Partial object oriented:-In this type of language classes and objects both are not compulsory for creating and running of application. That means we can write a program without using class and we can write classes in our program.


Example of partial object oriented language is C++.


Properties of java
Why java is famous:-java language having some properties that‘s why java is famous.

·         Java is a platform independent:-this is one of the greatest features of java. Java is developed for this feature because before development of java, James gosling and team want to develop a platform independent language for communication of electronic devices that should be control remotely.
Here platform means hard ware and operating system (Software) where application run. Due to this feature java application run on any hardware configuration and any operating system.
Platform independent is also known as compile once and run where, it means if we compile our java source code (.java file) on windows (OS) machine then after compilation it produce byte code (.class file).this byte code can run on any other machine like Solaris (OS) or any other operating system.java is a platform independent due to only byte code, that means java byte code is platform independent.
Java uses both language translator compiler and interpreter, java compiler (javac.exe) is responsible for generating byte code and java interpreter (java.exe) is responsible to execute this byte code.

·         Java is secure:-if any language directly uses operating system libraries for execution then those languages having security issues, but java uses own libraries for execution known as java runtime environment (JRE).


·         Java is portable:-portability means shifting or distributing applications onto different machines it is not a major issue but on every machine application should be run and produce unique output so java is a portable language.

Introduction of Java

Java is a high level programming language which is used for creating various types of software's or applications. Types of java applications:- 1)     Stand alone application 2)     Desktop based application          3)     Web based application 4)     Enterprise application etc. Stand alone application:- Stand alone application run on single machine without user interface and every stand alone application having main method. Desktop based application:- Desktop based application also run on single machine with user interface and every Desktop based application having main method. Web based application:- Web based application run on web, web based application not required main method but for such types of application need server. Enterprise application:- Enterprise application is category of web application where doing some business o...

Abstraction,Encapsulation And Inheritance

Abstraction  is a one of the great feature of Oops,in this feature hide entire details of product, show only requirement specifications(what product will do). The main purpose behind abstraction is to increase productivity or use of product without knowledge of product implementation. in this case the person don't know how product  was implemented but know how product works or action of product. In java abstraction is achieved by abstract class and interface,here interface provide 100% abstraction and abstract class provide partial abstraction. For example: - ATM machine is example of abstraction.  every technical and non-technical person use facility of ATM without knowing the entire process. they know if they click on withdraw button then they can withdraw money from ATM machine but they don't know when they click on withdraw button the request is send to the server and after go into database and so on. Here ATM machine show only requirement specificat...
