Imports and the asterix.

[Markus]

I'm just reading up on using MySQL in Java, and, during said reading, I stumbled across something that didn't quite make sense.

Consider the following, taken from http://java.sun.com/developer/techni...ndex.html#test.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.*;
 
public class MySQLclient {
[...]
 

If you are going to include every possible library (.*), why would you give specific libraries first? Am I misunderstanding the import java.pkge.* pattern?

@Markus
You're right: if the entire package (not 'library') is imported it is no use to import single classes from that package as well. It doesn't harm but it looks silly ;-)

kind regards,

Okay, thanks.

So, java.sql.Connection is not a library, but a package?

When I say import every possible library, I mean import every possible library in the package.

@Markus
No that Connection thing is a class; the * import imports all the classes contained in a package. The Connection class is stored in the java.sql package.
