Simplicity Java Crashcourse

These are the ones I tend to use the most, but there are MANY MORE and it just takes time to learn the ones that apply to you.

Sure thing, and thanks!Now just something that lets you log into your account, and send tweets in an input bar?Warning: This may be a series of tutorials, because I have to build you up to doing that.

I would appreciate some ideas as to what to teach you guys. I've installed disqus, so please leave a comment below!

I've decided against the Javadoc'ing process and will instead make Youtube videos. I will post the uploads as they come.

Think of Javadocs as fancy comments
