5.0 or 1.5.0?

Not only on the Sun website but also during installation of the new 5.0 JDK, the terms get mixed up so badly. The paths are "1.5.0" the javadoc API says "5.0", etc. Is there any info what's the final version number?

Java 2 SDK 5.0 contains JDK 1.5.0 and JRE 1.5.0

In fact, there's no more SDK, just JDK which indeed includes the JRE http://java.sun.com/j2se/1.5.0/docs/images/j2se5.gif(an option when you install).-Alexis
