Learning Java from scratch

Java is one of the most popular programming languages in the world, and good Java Programmers are one of the most sought after IT professionals today. This however does not mean that learning Java is a hard thing to accomplish, much the opposite, Java is an easy to learn programming language, with simple concepts and easy to understand syntax.

Keep also in mind that programming is so much more than just writing code in a particular syntax. Most of the time it is more of a way of approaching a problem, breaking it down into smaller pieces, and imagining structures and algorithms. It is therefore mostly an abstract and imagination exercise. This mental dexterity comes from experience, understanding what is going on, and doing the same thing over and over again. Yes, practice does make perfect!

To make this journey as exciting as possible we'll try to add a few interesting projects during the tutorials, but the examples in the first tutorials will be really really simple, but please don't despair! To run, we must first learn how to walk.
