Question

Suppose somewhere I import javax.servlet.http.HttpServlet.

My questions:

1. Does this mean: I could find a folder structure like javax/servlet/http somewhere and inside that HttpServlet.class file would be present?

2. If not, where exactly this class file could be found?

3. Does this mean: These are just nested namespaces with no relevance to folder structures?

4. Package name in the above mentioned import would be javax.servlet or javax.servlet.http? Probably both are packages and first one is super package of the later one?

5. How is this class file actually included? I’ve read import is not like c/c++ include.

Thanks.
