it's not long since the release of 1.5, but where's 5.0 from? Is it just the one in new version system mapping to the old 1.5?

I just feel a little bit curious, why did Sun do that? any ideas

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

Java 1.5 is not old. In fact, after reading your question, I see that it has been officially released. Until now, I was only aware of the beta. Java 1.5 is the same as J2SE 5.0.

one word: marketing.

We now have Java 2 SDK 5.0 version 1.5.0
We used to have Java 2 SDK 1.4.0
Originally it was simply JDK 1.1.0

Maybe in a few years someone will come up with a way to add even more numbers

it became java 2 when it was 1.2
so it becomes java 5 when its 1.5. But appearantly they are wimps and hedging. so its not quite Java 5...

no, it doesn't become Java 5.
It didn't become Java 3 or Java 4 either
