I see references to Java 1.4, Java 1.5, Java 2, and goodness knows other things also.

What is the difference between Java and Java 2? Is Java 1.5 Java or Java 2?

Any clarity would be greatly appreciated.

Jim,
Welcome to JavaRanch!

About 10 years ago, Java started with Java 1.1. There were a lot of changes, so when Java 1.2 came out, Sun started marketing it under the Java 2 label. Java 1.3 and 1.4 were also marketed under the Java 2 label. For copywrite reasons, we seem to be stuck with that label forever.

Note that Java 1.5 is officially called Java 5.0.

Once you master that, move on to the relative versions numbers of the J2EE, JSP and servlets...

I hear you. Right now, being in day 3 of discovering Java, I am finding the breath and expanse of my ignorance truely appalling. Hmmm, not even sure I'm spelling anything right either. This beginning of my Java Journey has my head spinning a bit.

I'll be glad when the 2 Java books I've ordered are delivered and I can sit down and do some serious reading.

If you want to have a chuckle, take a look at the Java Technology Concept Map
I once printed out that pdf (I think it was 4 sheets of paper x 3 sheets)
and pinned it to my cubby wall. Hah! That sure cleared things up

Don't let the scope of it all daunt you. Noone is an expert in all areas.
Some areas are so complicated, like Swing, that I wonder if more that a
handful of people are masters of all aspects of even that one area!

The good news is that you're in the right place. I think this is probably the most helpful community of Java Nuts in the world. If someone here doesn't have an answer to your question then you probably didn't have a question about anything programming related. ha ha Seriously, study your books; don't worry too much about version numbers; and above all ask the questions. Like Jeff said, no one is an expert, we're all still learning. Enjoy!
