How is import done in Java?

Question

For instance

import org.apache.nutch.plugin.Extension,

though used many times,

I\'ve no much idea what is done essentially.

Answer 1

Basically when you make a class you can declare it to be part of a package. I personally don't have much experience with doing packages. However, afaik, that basically means that you are importing the Extension class from the org.apache.nutch.plugin package.
