Question about java

When using the import command, I've seen statements like the following:

import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;


If the * sign indicates to import everything below the import.javax.servlet.jsp classes, why do they have to also put another line below to import everything under the javax.servlet.jsp.tagext.* as well?

Shouldn't that be included in the first import, since the * sign was used to indicate everything under the jsp directory, including jsp.tagext.*? Do java programmers do this just for ilustration purposes so whoever looks at the code knows they are using something from the tagext directory? or is is really neccessary to include the second line?

I am confused....

First, I'm not 100% sure of my explanation, it's just what I think the reason is. I'm not a Java programmer.

If you only use
import javax.servlet.jsp.*;
then afterwards you want to use foobar which is in tagext, you'll need to use
tagext.foobar blahblah

But if you do:
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
You can simply use:
foobar blahblah

Get it?

Again, I'm not sure of this, maybe someone can confirm it?

edit: some -> someone (sometimes my head thinks one thing, and my fingers type another)

Thanks a lot !!!

I got it now
