Hiding JFrame when button is clicked without stopping program

I have a jframe as part of a program where the user will populate an arraylist by pressing the add buttons. When they are finished populating the arraylist I want them to click the done button to hide the jframe while the program continues to run.

Is there a way to do this. Initially I was using System.exit(0) but this seems to terminate the program. 

public class Street extends JFrame {
    private static final Random randomNumbers = new Random();
    private ArrayList<Vehicle> vehicles = new ArrayList<Vehicle>();

    private JLabel messageJLabel; // displays vehicle that was added
    private JButton addBicycleJButton;
    private JButton addCarJButton;
    private JButton doneJButton;
    private Color background; // background color of application

public Street() {

    super("Street Simulation");

    background = Color.LIGHT_GRAY;

    messageJLabel = new JLabel("No vehicles added.");

    addBicycleJButton = new JButton("Add Bicycle");
    addBicycleJButton.addActionListener(

    new ActionListener() // anonymous inner class
            {
                public void actionPerformed(ActionEvent e) {
                    background = Color.LIGHT_GRAY;
                    Bicycle b = new Bicycle(2, 0);
                    vehicles.add(b);
                    messageJLabel.setText(b.toString()
                            + " added to vehicles");
                    repaint();

                } // end method actionPerformed
            } // end anonymous inner class
            ); // end call to addActionListener
    addCarJButton = new JButton("Add Car");
    addCarJButton.addActionListener(

    new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            background = Color.LIGHT_GRAY;
            Car c = new Car(4, 0);
            vehicles.add(c);
            messageJLabel.setText(c.toString() + " added to vehicles");
            repaint();

        } // end method actionPerformed
    } // end anonymous inner class
            );// end call to addActionListener

    doneJButton = new JButton("Done");
    doneJButton.addActionListener(

    new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            // code to exit goes here
            background = Color.LIGHT_GRAY;

            //I would like to have the jframe running in the background after this button is pushed.

            // System.exit(0);
            repaint();

        } // end method actionPerformed
    } // end anonymous inner class
            );// end call to addActionListener

    setLayout(new FlowLayout());
    add(addBicycleJButton);
    add(addCarJButton);
    add(doneJButton);

    add(messageJLabel);

} // end street constructor

See The Use of Multiple JFrames, Good/Bad Practice? for reasons why you shouldn't avoid you current design/thinking.

A better design would be to use CardLayout, see How to Use CardLayout for more details

The JFrame class has the method setVisible(boolean) which can be used for changing the visibility of a JFrame. For example, this.setVisible(false); to hide it.
