import HelloImport; Package required?

[news.verizon.net]

What grammer requires that an import must be for a package?
The following gets an error:

dir structure:
--------
src\
HelloImport.jav a
examples\
HelloWorld.java

src:
--------
12: package examples;
13: import HelloImport;
14: public class HelloWorld {
....

error:
--------
examples/HelloWorld.java [13:1] '.' expected
import HelloImport;
^
1 error
Errors compiling HelloWorld.java .

Given your directory structure, HelloImport.jav a is in the 'default'
package, which basically has no package. In that case, you don't need to
import it.

The cause of the error is a package name has more than one component to
it - 'HelloImport' is not a valid package name.
