I have problem with populating text fields upon selecting item in the combo box. I have 2 class, 1 to handle the GUI and the other, Controller to handle the database. Controller constructor takes the GUI as an input.
This is what I did in simplified version:
------------- GUI Class ------------
JComboBox combobox = new JComboBox();

public void comboboxListener(ActionListener al)
{
combobox.addActionListener(al);
}

-------------Controller---------------
Constructor:
GUI.comboboxListener(new combolistener());

class combolistener implements ActionListener{
public void actionPerformed(ActionEvent ae){
GUI.txt1.setText("");
GUI.txt2.setText("");
}
}
