import question

At the top of my java program is a series of import statements.

here they are:

import java.io.*
import java.util.*
import java.sql.*
import java.jdbc.*

I get an error that states that java.io doesn't exist. How does java know where to look for the stuff that it is importing? Is it in the classpath?

Ya, there's a tools.jar file that needs to be in your classpath. It should be in the j2sdk/lib directory.

If that's not in your classpath you should be getting errors on the other packages, too, though.
