Driving me insane - Program not working as it should ><

[mainy]

Hello,

I have four classes. Select, Login, Connect. I will break the situation down as the total code of my project is about 3000 lines and I doubt you want to shift through all that :p

Basically, MainGui uses Connect for a database connection. I have something like this set up:

public class MainGui extends javax.swing.JFrame implements Printable {

public MainGui() {
initComponents();
}

public String url = new String();

Connect conDatabase = new Connect(url);

The problem is, when I make a new object of this class in the Select class like so:

private void jButton2MouseClicked(java.awt.event.MouseEvent evt) {
MainGui m = new MainGui();
m.url = "jdbc:mysql://91.266.176.244:3306/example_database"
m.setVisible(true);
}

It doesnt work, it cant connect to the database. The reason is, when I create a new Object of MainGui (MainGui m = new MainGui()) it loads the current configuration of MainGui before I can edit the url.

Is it possible to set the m.url = "addy" before initalising the object?

One way would be to make the constructor take the url so when you construct you know the url to set. HOWEVER, that is a smell. GUI code should have nothing to do with connecting to databases. And you certainly should not be connecting to the database on the EDT.
