Introduction to Object Oriented Programming Concepts (OOP) and More

Introduction to Object Oriented Programming Concepts (OOP) and More
Recommended framework: Table of contents 1. Introduction I have noticed an increase in the number of articles published in the Architecture category in CodeProject during the last few months. One day I read an article that said that the richest two percent own half the world's wealth. Coming back to the initial point, I noticed that there is a knowledge gap, increasing every day, between architects who know how to architect a system properly and others who do not. 2. This article began after reading and hearing questions new developers have on the basics of software architecture. As I see it, newcomers will always struggle to understand the precise definition of a new concept, because it is always a new and hence unfamiliar idea. 3. This article is an effort to provide an accurate information pool for new developers on the basics of software architecture, focusing on Object Oriented Programming (OOP). 4. 4.1. 4.2. 4.3. OOP is a design philosophy. 1. Related:  Getting Started

The Downfall of Imperative Programming | FP Complete Imperative programming is in my bloodstream. I've been a C++ programmer for most of my life. I wrote a book about C++. I helped Andrei and Walter design an imperative language D. If I dabbled in functional programming, it was mostly to make my imperative programs better. Over the years I also developed a real passion for concurrent programming. There is no doubt in my mind, and most experts agree, that concurrency and parallelism are the future of programming. I have recently attended the Multicore DevCon in San Jose, which was part of a big DesignWest Expo. Remember the times when progress in software was driven by adding abstraction layers between programming languages and the details of processor architectures? I may surprise you that the state of the art in parallel programming is OpenMP and OpenCL. But maybe this is just a temporary state of affairs and there is ongoing work to ratchet the levels of abstraction back to where they'd been. Here's the key insight:

Object Oriented Programming Tutorial - Objects Objects are the central idea behind OOP. The idea is quite simple. An object is a bundle of variables and related methods. method is similar to a procedure; we'll come back to these later. The basic idea behind an object is that of simulation . methods associated with that object, in other words, functions that modify the objects attributes. A few examples should help explain this concept. Drink! Say we want to write a program about a pint of beer. TYPE BeerType = RECORD BeerName: STRING; VolumeInPints: REAL; Colour: ColourType; Proof: REAL; PintsNeededToGetYouDrunk: CARDINAL; ... Now lets say we want to initialise a pint of beer, and take a sip from it. VAR MyPint: BeerType; BEGIN ... (* Initialise (i.e. buy) a pint: *) MyPint.BeerName := "Harp"; MyPint.VolumeInPints := 1.00; ... ... (* Take a sip *) MyPint.VolumeInPints := MyPint.VolumeInPints - 0.1; ... We have constructed this entire model based entirely on data types A method is an operation which can modify an objects behaviour. .

Alice Programming Tutorial, by Richard G Baldwin Learn to Program using Alice Getting Started In this lesson, you will learn how to download, install, and test the Alice programming environment. You will also learn how to access the tutorials that are provided by the developers of Alice and how to run the example programs that are provided by those developers. Published: March 26, 2007Last updated: April 22, 2007By Richard G. Alice Programming Notes # 100 Preface First in a series This is the first lesson in a series of tutorial lessons designed to teach you how to program using the Alice programming environment under the assumption that you have no prior programming knowledge or experience. My objective in writing this series of lessons is to make it possible for people who have no previous programming experience to learn programming fundamentals using Alice. A lot of fun Because Alice is an interactive graphic 3D programming environment, it is not only useful for learning how to program, Alice makes learning to program fun. The bottom line

The Perils of JavaSchools by Joel Spolsky Thursday, December 29, 2005 Lazy kids. Whatever happened to hard work? A sure sign of my descent into senility is bitchin' and moanin' about "kids these days," and how they won't or can't do anything hard any more. “You were lucky. When I was a kid, I learned to program on punched cards. When I started interviewing programmers in 1991, I would generally let them use any language they wanted to solve the coding problems I gave them. 99% of the time, they chose C. Nowadays, they tend to choose Java. Now, don't get me wrong: there's nothing wrong with Java as an implementation language. Wait a minute, I want to modify that statement. Instead what I'd like to claim is that Java is not, generally, a hard enough programming language that it can be used to discriminate between great programmers and mediocre programmers. You used to start out in college with a course in data structures, with linked lists and hash tables and whatnot, with extensive use of pointers. Still. Feh. Next:

Indoor Autonomous Positioning SCP technology makes it possible to provide reliable, consistent, and accurate indoor positioning without the support of network infrastructure and services. By exploiting freely available signals including GPS, cellular, digital television, and wireless LAN (e.g. WiFi), SCP based Doppler Aided Inertial Navigation (DAIN) determines location through a sensor fusion approach. Combining inertial, magnetic, and gravity data with the SCP RF observables, DAIN provides continuous position, velocity, and direction information. A fundamental breakthrough in indoor positioning, SCP DAIN is ideal for emerging location enabled applications hosted on smart phone devices. DAIN is an ideal enabler for both consumer and commercial applications.

What Is an Interface? (The Java™ Tutorials > Learning the Java Language > Object-Oriented Programming Concepts) As you've already learned, objects define their interaction with the outside world through the methods that they expose. Methods form the object's interface with the outside world; the buttons on the front of your television set, for example, are the interface between you and the electrical wiring on the other side of its plastic casing. You press the "power" button to turn the television on and off. In its most common form, an interface is a group of related methods with empty bodies. interface Bicycle { // wheel revolutions per minute void changeCadence(int newValue); void changeGear(int newValue); void speedUp(int increment); void applyBrakes(int decrement); } To implement this interface, the name of your class would change (to a particular brand of bicycle, for example, such as ACMEBicycle), and you'd use the implements keyword in the class declaration: Implementing an interface allows a class to become more formal about the behavior it promises to provide.

Introduction to Java programming, Part 1: Java language basics Introduction to Java programming, Part 1 Object-oriented programming on the Java platform Find out what to expect from this tutorial and how to get the most out of it.

Revenge of the Nerds May 2002 In the software business there is an ongoing struggle between the pointy-headed academics, and another equally formidable force, the pointy-haired bosses. Everyone knows who the pointy-haired boss is, right? The pointy-haired boss miraculously combines two qualities that are common by themselves, but rarely seen together: (a) he knows nothing whatsoever about technology, and (b) he has very strong opinions about it. Suppose, for example, you need to write a piece of software. Why does he think this? Well, this doesn't sound that unreasonable. But all languages are not equivalent, and I think I can prove this to you without even getting into the differences between them. Presumably, if you create a new language, it's because you think it's better in some way than what people already had. So, who's right? Once you start considering this question, you have opened a real can of worms. The disadvantage of believing that all programming languages are equivalent is that it's not true.

How to build your own Linux distro Since Manchester University's Owen Le Blanc released MCC Interim Linux (generally agreed to have been the first Linux distribution), way back in 1992, there have been hundreds of ways to get the world's favourite free software operating system on to a computer. The diversity of alternatives reflects the diversity in the development community, with distros split along technical, functional, linguistic and even ideological lines. There have been large distros, tiny ones, bleeding edge and rock-solid stable distros. Easy for the newbie to install, or downright impenetrable to the uninitiated. Created exclusively with free software as a badge of pride, or so proprietary in attitude that not even the toolchain was fully GNU (hello Red Flag Server 4.1, built with the Intel compiler in 2004). So with all the variety that's already out there, why would anyone want to create their own distro? What this amounts to is that it doesn't take much to warrant a new distro. Which base? The simple choices
