Hmm... Interesting question...

From the JDKTM 5.0 Documentation at http://java.sun.com/j2se/1.5.0/docs/index.html

This document covers the JavaTM 2 Platform Standard Edition 5.0 Development Kit (JDK 5.0).

You can draw your own conclusions as to where it Java 2 or not...

Hmmm....
So there is a developer and product version but both are for the java 2 platform, if I got it right.

Yup... the Java 2 Standard Edition JRE and SDK (JDK)...

where JRE = Java Runtime Environment
and SDK = Software Development Kit ( Java Development Kit )

You are probably not the only one to find all the numbers confusing. I, for one, wish that there was only a single version number for each release of Java.

This is one of my pet peeves with Java, but this is kinda how it got going.

First there was Java 1.0 and then 1.1.

When Java 1.2 came out Sun basically said this is such a big improvement over 1.1 we will call it Java2, but we'll leave the version number as 1.2 so we can confuse people.

Then Java2 1.3 and 1.4 came out and things were kinda quite on the numbering.

Then 1.5 came out and once again Sun said this is a big change so we need to change the version number. Let's be as confusing as possible so we will still call it Java2, but add a 5.0 version and we'll still keep the 1.5 version number around.

What should have happend was when Sun decided it wanted to call the 1.2 version Java2 it should have given it the version number 2.0 rather than 1.2. Then we could have had 2.1, 2.2, 2.3, ect.
Then when the new, now 5.0/1.5, version came out they could have called it Java3 and given it the version 3.0 and continued from there with 3.1, 3.2 ect.

On the '6.0' release they should finally drop the 1.6 and Java2 versioning and just call it Java 6.0

But that would just be too easy for those marketing types
