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

Buliding off of Thomas' answer, org.apache.nutch.plugin is a path to the class file(s) you want to import. I'm not sure about this particular package, but generally you'll have a .jar file that you add to your classpath, and your import statement points to the directory "./[classpath]/[jarfile]/org/apache/nutch/plugin"
