Java Tutorial 1 : First Application

Java is a great language for doing certain things. It's the language I grew up on, and so I'm a little biased, but you could do a lot worse as it's pretty well known and easy to use for what it can do.

NOTE:
If you are getting this error:
"'javac' is not a recognized as an internal or external command, batch file or operable program."

It is because you do not have the JDK (Java Development Kit) installed. Because this tutorial is meant for all platforms (Mac, Windows, Linux, etc) I do not show how to download and install the JDK as it is different for each operating system. In order to fix this error, just look for a good tutorial on youtube by searching for "download and install jdk on windows" or "... on mac" or "on ubuntu" etc...
