Lokesh:

There's no difference, they both mean the same thing.

Use one as a pet name for the other.

[Pedantic mode]Actually neither is an official name. The official name is Java 5, which you will find as a download called jdk1.5.0[/pedantic mode]

I thought Java 5.0 was the official name, and the 0 got dropped for Java 6. See also http://en.wikipedia.org/wiki/Java_version_history

From Sun's JDK 5 documentation: Version 1.5.0 or 5.0?

Both version numbers "1.5.0" and "5.0" are used to identify this release of the Java 2 Platform Standard Edition. Version "5.0" is the product version, while "1.5.0" is the developer version. The number "5.0" is used to better reflect the level of maturity, stability, scalability and security of the J2SE.

The number "5.0" was arrived at by dropping the leading "1." from "1.5.0". Where you might have expected to see 1.5.0, it is now 5.0 (and where it was 1.5, it is now 5).

It's silly, but Sun insists on using two version numbers.

@Rob: Sun still maintains two version numbers with Java 6: JavaTM SE 6, Platform Name and Version Numbers

Yeah, the 1.x version will probably remain. The next version will be both Java 7 and Java 1.7.0.

On this Sun page they call it J2SE 5.0. The naming conventions seem to be different every time I look. I think I shall give up trying to remember what Java is called.

Up until Java 5, they called it "J2SE", and since Java 6 they dropped the "2" in the name and call it "Java SE" instead of "J2SE", "Java EE" instead of "J2EE" etc.
 
It is sorta covered in the JavaRanch Style Guide.
