Well, hold your breath. According to Graham Hamilton's blog, Sun is
going to change the names of the platforms again: the Java marketing
team have decided to simplify the naming system by dropping the "2" from
the platform name and the ".0" from the release number.
J2SE -> Java SE
J2EE -> Java EE
J2ME -> Java ME
The next release after J2SE 5.0 (codename Tiger) will thus become "Java
SE 6" (Mustang).

Well that would be a reasonably sensible move but could lead to more
confusion, particularly for the enterprise edition. "J2EE" has become
synonymous with "enterprise Java" and is indispensible in the buzzword
bingo world of IT recruitment. HR departments will be especially
confused, particularly as "Java 2 Enterprise Edition" to "Java Enterprise
Edition" looks like a regression.

There are some significant syntax changes from 1.4.2 to 1.5.0 (also called
J2SE 5.0). If you are just programming for yourself then go for 1.5.0. If
you want to be able to write code that 1.4.2 can use then be careful. Some
1.5.0 code will not work on 1.4.2 but all 1.4.2 code will work on 1.5.0.

With Sun there is marketing and there is development. It seems the two
will always differ. Here is the basic run down:

Dev Marketing
--- ---------
1.0 Java 1.0
1.1 Java 1.1
1.2 Java 2 or J2SE
1.3 J2SE 1.3
1.4 J2SE 1.4
1.5 J2SE 5.0
1.6 Java SE 6

To be honest, I probably got something wrong. I always talk in terms of
what `java -version` or `java -fullversion` outputs. All this Java 2,
J2SE, Java SE stuff is really just marketing and branding. I let our
marketing people deal with what (tm) and (c) stuff goes in the
documentation and adverts.

I'd recommend 1.5.0_03-b07. The 1.6.0 is the next release so you want to
stick with something that has been out there in production environments.
That would be 1.5.0.

Hmmm, never thought about this. I was always thinking it didn't matter
what I use because everyone I work with knows what I'm talking about
regardless of what terminology I am using.

I could get screened out of an interview just because I used J2EE rather
than Java EE or Java Enterprise Edition. Something to remember next time
I'm updating my resume.

I just installed jdk1.5.0_04 on a Windows machine and compiled an
application. The 'minimize' button on the right top of the frame
looks crippled. Lightweight, so I suppose java put it there. When
full size, the button looks OK.

It's marketing, you can't have Java 1.5 when C# has 2.0, since 2.0 is
higher than 1.5, indicating C# has surpassed Java (it hasn't by the
way).

It's nothing compared to Solaris. SunOS 5.7 = Solaris 2.7 = Solaris 7.
