The title of the post is intentionally non technical ........and it has some meaning....How?The reason is quite simple....as the name suggests .......you already know the stuff that will be presented in the current post.....only difference would be we will look this entire stuff from different view point.....This post exclusively deals with answer asked in the last part of the previous post.We will be thinking of one real world entity (object) & we will try to find out all the major pillars of OOPs in it..which will be a proof of concept for the discussion we had in earlier post.Ready? Get...Set...Go.....I am thinking of Personal Computer as real world entity.Now biggest question is how Abstraction, Encapsulation, Inheritance , Polymorphism and Modularity applies to this object?I am sure you must have considered other objects as well & must have done some research on this...right?Personal Computer (PC) as an object is a very good example to understand these major pillars.If i have t...

Object Model -Buzzwords & Reality
2007-02-03 09:10:00
Hello All,Meeting after very long time really.......Today we will spend sometime understanding buzzwords in Object Model or in general Object Oriented Programming Paradigm.We will talk about:AbstractionEncapsulationInheritance Polymorphism &ModularityThese terms are very frequently used by many people and really these are buzzwords in OOP. few people call these as Major Pillars in OOPs. obviously there are Minor Pillars as well(More on this later).We will define these terms one by one & individually we will understand how simple they are in reality. At the end for sure we will understand all the terms with a simple example. Rather we will consider one object and we will apply all these Buzzword s to that object.Let's go step by step1) AbstractionAbstraction refers to identifying key aspects (and obviously ignoring/ dropping the rest) of an object/entity for the specific application.e.g. If we consider Person as a object , then how you will represent Person ?You will write a class...

What is an Object
2007-01-06 06:39:00
In continuation with earlier discussion, Let's try to explore "What is an Object ?". I am sure you will correctly answer it as "It's an entity with State & Behavior". In earlier discussion we have explored what is a class & how to use that class in actual programming with simple (although bit non-realistic) example of Car & CarDemo classes. If you have understood the usage of a class, then you have unknowingly dealt with object as well, How? See, In CarDemo class when we said:Car carOne=new Car();Car carTwo=new Car();Don't worry too much how these Java classes are compiled & executedNote for C Programmers: For the time being assume 'new' similar to 'malloc(...) ' functioncarOne & carTwo objects of type Car.carOne has some state(values of data members) & carTwo has some other State although behavior(methods) is common as they are of type Car.Few important things to note from example are1) We are changing State of any object by "Invoking methods" & do not change data m...

What is a Class?
2006-12-30 07:21:00
In earlier post we have emphasized on "Need of an Object Oriented Programming". In this post & subsequently we will deal with very basic concepts of OOPs viz Class and Object.If you have understood earlier discussion of Need of OOPs , It won't be very difficult to understand what is a class. if we quickly summarize earlier discussion we said that "Every entity in real world is an object(having State & Behavior) & Software objects model / represent real world objects. "If you are with me, can we say by simple observation that In real world we often come across many objects of same kind. e.g. Thousands of Cars of same company, make, model right? Extend this for any other object you have thought of earlier & you will find plenty of such cases...am i right? do you agree?One more example could be many houses in certain project with same look, built etc..In case of a Car or House (or for any other object for that matter) they are built from certain blueprint. There would be a drawi...

Today we will make a entry into the world of Object Oriented Programming (We will call it as OOPs henceforth)Whenever people discuss anything seriously about Software & Software Development for that matter, somebody surely makes use of buzzwords like OOPs, Moularity, Reusability,Abstraction, Inheritance, Polymorphism & what not. Use of a buzzword is not a big deal however, Knowing the meaning of these Buzzwords is really going to make a difference. This is not only true for discussions but for successful Software Design & Development.Those who are intrested in making career in IT Industry should concentrate more on these concepts rather absorb these concepts. Thses concepts could be used for cracking Technical Interviews with any company in this world as well as they make sense when we are deeply involved in Software Development(initially) & Software Design (later on as a Software Architect/ Product Architect). Those who are alredy aware of these concepts could read this pos...

Java is an Object Oriented Prog ramming Language & it's very essential to learn Object Oriented Program ming Concepts before we jump into actual Java Programming. In my subsequent posts we will address different issues related to Object Oriented Programming aspects.We will have following Objectives when we start exploring world of Object oriented Programming1. Need of an Object Oriented Programming2. What is a Class?3. What is an Object?4. Object Model -Buzzwords & Reality5. Difference between Procedural Approach & Object Oriented Programming
