Action sur checkbox

Bonjour,



je créer deux checkbox et je créer deux panel

mon objectif est je veux quand je coche la case par exemple

le deuxième panel sera rempli par :par exemple un bouton et un textfield

je créer une action sur jCheckBoxSendMail .

et je suppose que la création de panel2 avec ces composants sera fait par un test si je coche ce CheckBoxSendMail


je fait ce code :

public class Test extends javax.swing.JFrame {
 
   
    public Test() {
        initComponents();
    }
 
   
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {
 
        jPanel1 = new javax.swing.JPanel();
        jCheckBoxemail = new javax.swing.JCheckBox();
        jCheckBoxSms = new javax.swing.JCheckBox();
        jPanel2 = new javax.swing.JPanel();
 
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
 
        jPanel1.setBackground(new java.awt.Color(255, 255, 255));
 
        jCheckBoxemail.setText("envoi email");
        jCheckBoxemail.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jCheckBoxemailActionPerformed(evt);
            }
        });
 
        jCheckBoxSms.setText("envoi sms");
 
        javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
        jPanel1.setLayout(jPanel1Layout);
        jPanel1Layout.setHorizontalGroup(
            jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

                    .addComponent(jCheckBoxSms))

        );

    // Variables declaration - do not modify
