Is "Java" and "Java 2" means the same thing?

Some books use "Java programming" and some use "Java 2 programming". Any differences between the two?
Thanks.

It means the same thing.

For some reason, when Java version 1.2 came out long ago, Sun decided to call it "Java 2" - "J2SE" (Java 2 Standard Edition), "J2EE" (Java 2 Enterprise Edition) etc.

Later, when Java 1.5 or 1.6 came out, they decided that the "2" didn't mean anything and dropped it from the official naming again, so now it's called "Java SE", "Java EE" etc.
