OOP Core Concepts: Encapsulation
In our current society, we are more than used to live with technology gadgets, most of them not even in the minds of our ancestors. Things as common and “simple” as a remote for our TV, just to mention one, that avoid the need to stand up for interacting with…
Programming 101: Subroutines
At the beginning of our experience in cooking, we usually don’t start with difficult or too complex recipes, instead, we start with some very simple ones that help us to gather experience and knowledge in the art of cooking… Let’s suppose by just a moment that, due to our great…
OOP in Java: Objects and Classes
As mentioned in a previous post, object-oriented programming is a paradigm in which we model our problem’s actors (objects) using some structures called classes. A class defines the common structure of all objects (of the same type) will share. An object could be described as a sort of entity that…
Java: A First Sip!
For the past 25 years, Java, with more than 40 billions of Java Virtual Machines running around the world, has been the leading programming platform. Although, its beginnings are far from what we know right now for this programming language. Once upon a time in a not that far away…
Hello World Java
Tools we need JDK 8 (could be a newer version as well) The Java Development Kit is the development environment we use for writing applications using the Java Programming language An IDE (Integrated Development Environment), This tool help developers to go faster in the development of applications, even though is…
Programming 101: Loops
¿What happens when we are serving soda from a dispenser? Usually, we start our process by putting the glass below the dispenser and opening it in order to fill our cup, but it starts to fill out with foam, and we wait until it disappears and continues filling our cup…
Web Services: A glimpse
The universe of programming languages is vast and full of technologies, and it has always been very difficult to make products of different platforms communicate among them. In our current world, it has become imperative to make this communication more fluid, as we now are able to provide services across…
Object Oriented Programming: Classes and Objects
When writing a computer program, there are different approaches we can follow to solve a specific problem. Some people can focus on solving it by creating subprograms or functions to solve each small part of the problem (Structured programming paradigm). In an Object-Oriented Programming (OOP) style, on the other hand,…
Programming 101: Conditionals
We have defined programs like a list of instructions similar to cooking’s recipes, which indicate to computers what to do and how to do it in order to achieve some goal. Sometimes it is necessary to make decisions within programs and these decisions lead us to one path of instructions…
Programming 101: Variables and Operations
As mentioned in a previous post, programs are lists of instructions that indicate to devices how to process some input data to produce the desired output. To do so; programs must keep a registry of those input values, and of every other resulting data, this storage of information is made…
