Java Checkbox Save

i Need some help with saving checkboxes, im new in this and hope i'll get some help.

What i want to do: I want to save the Settings:

if(e.getSource() == einstellung){


        JFrame meinJFrame = new JFrame();
        meinJFrame.setTitle("JRadioButton Beispiel");
        meinJFrame.setSize(400,300);
        JPanel panel = new JPanel();
        panel.setBackground(Color.BLACK);
 //Checkbox 1

        JCheckBox check = new JCheckBox("Activate Wall at the score of 500k.", false);

        panel.add(check);

      //Checkbox 2
        JCheckBox check1 = new JCheckBox ("Activate Trump Tower at the score of 1 million.", false);

        panel.add(check1);           

        meinJFrame.add(panel);
        meinJFrame.setVisible(true);

It's for a little game i am creating and i just want to save the checkboxes, so they are checked (or not) when i start the Programm again.

The full code (please do not use it for private things like using it for your own game or sth like that):

private JButton schliessen;
private JButton einstellung;
private JButton info;
private JButton ende;
private JTextField Textbox;

JCheckBox redCB, blueCB, greenCB, yellowCB;


public static void main(String[] args) throws Exception {






    frame frame = new frame("Jump Trump Menu");
    frame.setResizable(false);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400,460);
    frame.getContentPane().setBackground(Color.BLACK);  


    frame.setLayout(null);
    frame.setVisible(true);














}








public frame(String title) {

    super(title);

    schliessen = new JButton("Play");
    schliessen.setBounds(120,40,160,40);
    schliessen.addActionListener(this);
    add(schliessen);
    schliessen.setBorderPainted(false);
    schliessen.setFocusPainted(false);
    schliessen.setContentAreaFilled(true);
    schliessen.setHorizontalAlignment(JButton.CENTER);

    einstellung = new JButton("Settings");
    einstellung.setBounds(120,120,160,40);
    einstellung.addActionListener(this);
    add(einstellung);
    einstellung.setBorderPainted(false);
    einstellung.setFocusPainted(false);
    einstellung.setContentAreaFilled(true);
    einstellung.setHorizontalAlignment(JButton.CENTER);

    info = new JButton("Special Contract");
    info.setBounds(120,200,160,40);

    add(info);
    info.setBorderPainted(false);
    info.setFocusPainted(false);
    info.setContentAreaFilled(true);
    info.setHorizontalAlignment(JButton.CENTER);

    ende = new JButton("Exit");
    ende.setBounds(120,280,160,40);
    ende.addActionListener(this);
    add(ende);
    ende.setBorderPainted(false);
    ende.setFocusPainted(false);
    ende.setContentAreaFilled(true);
    ende.setHorizontalAlignment(JButton.CENTER); 

    Textbox = new JTextField("Pre Alpha 0.0.5");
    Textbox.setHorizontalAlignment(JTextField.CENTER);
