Watch the complete web series "Java & Web" on YouTube. It's complete, comprehensive and conceptual.

Many of these are in the top ten percent of Java video tutorials that can be found on YouTube, and very nearly all are in the top twenty percent. It is unfortunate for other people that they miss this channel. Even with not seeing new videos for a little while, there is a LOT to go thru here already, and again, almost all of it on very useful topics and presented very clearly. Even topics one knows it is great to watch these for review, because you go at a pace that one doesn't waste too much time watching even if there will only be one or two points that the viewer needed to be reminded on or refreshed on. Admittedly, when watching totally new material, some may need to go back and re-watch some parts, but YouTube makes that spectacularly easy to do. Very good content.

I also would name reference variables to Wrapper objects with a single initial Capital Letter, like I, B, C or L, but have stopped doing it because it causes instance method calls to appear as if they were instead static method calls on classes named I, B, C or L. Of course they aren't, but when I watch someone else do it (instead of myself) I realize it can make the code harder to read.
