I am new to Java and Swing if anyone could point me in a direction it'd be appreciated.

This is one class building my frame. I believe I have to use the ChangeListener you see added but have done nothing but copy a method from this site.
All I want to accomplish with my tabs is set them back to their default state if another tab is clicked.. simply meaning set the the text fields and list selection back to a state etc.

Will a method I need to make for this be in my classes for the panels or the frame? Will I need to change the scope of anything? I've been browsing for an answer but haven't found what I'm looking for.

public class GUIFrame extends JFrame implements ChangeListener {

JTabbedPane tabs;

public GUIFrame(String title) 
 JFrame frame = new JFrame(title);
 Container c = frame.getContentPane();
 pack();
 buildGUI(c);
 setFrameAttributes(frame);

private void buildGUI(Container c) 
 tabs = new JTabbedPane(JTabbedPane.TOP, JTabbedPane.WRAP_TAB_LAYOUT);
 MedicalSystemIO medLogs = new MedicalSystemIO();
 c.setLayout(new BorderLayout());
 c.add("Center", tabs);
 tabs.addTab("Specialty", new SpecialtyPanel(medLogs.getListOfSpecialties()));
 tabs.addTab("Doctor", new DoctorPanel(medLogs.getListOfDoctors()));
 tabs.addTab("Patient", new PatientPanel(medLogs.getListOfPatients()));
 tabs.addTab("Treatment", new TreatmentPanel(medLogs.getListOfTreatments(), medLogs.getListOfPatients()));
 tabs.addChangeListener(this);



@Override
public void stateChanged(ChangeEvent e) 
 // TODO Auto-generated method stub
 if(e.getSource() instanceof JTabbedPane)
 tabs = (JTabbedPane) e.getSource();
 System.out.println("Selected paneNo : " + tabs.getSelectedIndex());

This is a method from a class "public TreatmentPanel(...)". I did not include most of the methods but some that are used are ActionListener and ListSelectionListener.

 private void buildPanel(ArrayList<Treatment> treatments, ArrayList<Patient> patients) 

 setLayout(new BorderLayout());

 model = new DefaultListModel<Treatment>();
 list = new JList<Treatment>(model);
 list.setModel(model);
 list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
 list.setSize(20,80);
 list.setFixedCellWidth(150);
 scroll = new JScrollPane(list, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
 JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

 this.patients = new ArrayList<Patient>(patients);
 this.treatments = new ArrayList<Treatment>();

 JPanel jpaInput = createInputPanel();
 JPanel jpaProcess = createProcessPanel();
 JPanel jpaOutput = createOutputPanel();

 add("North", jpaInput);
 add("South", jpaProcess);
 add("Center", jpaOutput);
