How do I keep file menu open after CheckBox has been selected?

Question

The following represents a written code for a menu with checkboxes. I would like the menu to stay open after a check box has been selected. Does anyone have a suggested modification for this to occur?
Thanks,
JR
public class NewJFrame extends javax.swing.JFrame {
/** Creates new form NewJFrame */
public NewJFrame() {
initComponents();
/** This method is called from within the constructor to
* initialize the form.

Sorry Jack.
Here is the code so that it appears more readable whenever it gets moved.
public class NewJFrame extends javax.swing.JFrame {
    /** Creates new form NewJFrame */
    public NewJFrame() {
        initComponents();
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.

        jCheckBoxMenuItem3 = new javax.swing.JCheckBoxMenuItem();
        jMenu2 = new javax.swing.JMenu();
        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
        jMenu1.setText("File");
