How to set a database name for fetching metadata?

Question

How can I tell an already-existing Connection what its database should be, in such a way that I can successfully get MetaData from the connection?
If I use the following code, everything works fine:
     Connection connection;
     DatabaseMetaData metadata;
     ResultSet rs;
     connection = DriverManager.getConnection("jdbc:mysql://Localhost/archival", mUser, mPassword); // replace this line
     metadata = connection.getMetaData();
     rs = metadata.getTables(null, null, "%", null);
But if I replace the fourth line above with these three lines:
     connection = DriverManager.getConnection("jdbc:mysql://Localhost/", mUser, mPassword);
     Statement stmt = connection.createStatement();
     stmt.execute("USE archival");
then I get a SQLException "Incorrect database name: ''". I would really prefer to factor my getConnection() code so that it doesn't have to know what the database-name is, but in order to do that I need to be able to set the database-name after the connection has been created, and still get MetaData on the connection.
TIA for any help!

Umm I probably totally don't understand the question, but you can change the name in the IDE,
and in code you can name it to whatever you want
Dim WhatEverNameIWantToGive as new button Dim secondbutton = WhatEverNameIWantToGive
or maybe you mean
public class mybutton
inherits button
'your custom code here
end class
