I'm not sure there is a difference between "Java" and "Core Java". Perhaps you're confusing the responsibilities of a system, ie, the core components and other components making use of the core. In most core system implementations you'll find the lowest level of implementation, ie, actual database read/writes, network-layer communication to various resources -- basically the realization of data into objects that make the higher tiers more palatable to a non-core developer. Perhaps on the bean/jsp tier, a developer can say, carInstance.go() and not have to worry that the core is communicating via RMI to a box in Germany that is controlling a new Volkswagen prototype (that's core java to me).
Hope this helps!

Are you referring to the series of books from Sun that all start with "Core Java" in their titles? That isn't referring to something specifically called "Core Java" it simply uses the term "Core" to mean "Essential".

My interpretation of his question is the
"Core" Java - what is in the JDK, and
extensions - packages with javax. For example,
Collections are core - Servlets are not.
First - we need a clarification on what the
question really is - Suresh - can you clarify?

Actually, in an interview, interviewer asked me about this. In some computer centres, they are offering courses like Java and Core java. I would like to know, whether there is any technical, conceptwise or any differences between these two.
That's it.
I agree. Here's the link:
