How to add selected check boxs to arraylist

Hey, I'm pretty new/bad at Java and completely new to GUI.
How do I add selected checkboxs to an arraylist? I've tried looking around but can't really find anything that helps.
Any help would be appreicated!





public class testProcedures extends JPanel
{
private static JLabel procedureLabel;
private static JButton orderButton, resetButton, quitButton;
private static JTextArea orderDetails;
private static JCheckBox[] procedure;
private static int NUM_PROCEDURES= 5;
static JTextField patientIDField;


public testProcedures()
{
super();
patientIDField = new JTextField("Enter Patient ID Number", 25);
add(patientIDField);

setPreferredSize(new Dimension(350,300));
setLayout(new GridLayout(1,1));
add(pane, new Dimension(1,1));
setVisible(true);

JFrame frame = new JFrame("Procedures");
frame.setContentPane(split);
frame.pack();
frame.setVisible(true);*/
}

public void selectProcedures()
{
procedureLabel = new JLabel("Select Procedures");
procedure= new JCheckBox[NUM_PROCEDURES];
procedure[0] = new JCheckBox("Extraction",false);
procedure[1] = new JCheckBox("Filling",false);
procedure[2] = new JCheckBox("Cleaning",false);
procedure[3] = new JCheckBox("Crown",false);
procedure[4] = new JCheckBox("X-Ray",false);


orderButton = new JButton("Set Procedures");
orderButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent event){



processOrder();
}
});

resetButton = new JButton("Reset Patient Procedures Form");
resetButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent event){
resetForm();
} });

quitButton = new JButton("Quit Program");
quitButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent event){

System.exit(0);
} });

orderDetails = new JTextArea("Awaiting Procedures....",5,40);
add(procedureLabel);
for (int index=0; index < NUM_PROCEDURES;++index)
add(procedure[index]);
add(orderButton);
add(resetButton);
add(quitButton);
add(orderDetails);
}

static void processOrder()
{
String order = "Procedures Selected:";
boolean proceduresSelected= false;

String patientID = patientIDField.getText();
int patientNumb = Integer.parseInt(patientID);
ArrayList<Patient> PatientList = DentistTabbed.getPatientList();
ArrayList <Procedure> procList = new ArrayList<Procedure>();
for (int index=0; index < NUM_PROCEDURES;++index)
if (procedure[index].isSelected())
{
//here
for(Patient pat: PatientList)
{
if(pat.getPatientNumber()==patientNumb)
{

//pat.addProcedure(procedure);
//procList.add(procedure);

}
}
//here
proceduresSelected = true;
order += "\n"+ procedure[index].getLabel();
}
if (!proceduresSelected)
order += "No procedure Selected.";
order += ".";
orderDetails.setText(order);
}
