comboboxs and buttons, please

[carlos123]

public class ButtonListener implements ActionListener
     {
           public void actionPerformed(ActionEvent event)
      {
            JComboBox yearcombo = (JComboBox)event.getSource();
          JComboBox gendercombo = (JComboBox)event.getSource();
           
           JComboBox statecombo = (JComboBox)event.getSource();

How do i give the combo box and j button's the action focus and make combo class fields and give the combo boxes the necessary scope

That's a lot of questions.
Open the API docs page for JComboBox and see the methods available to you.
Also read Sun's tutorial on the JComboBox section.
