How to close a JFrame window when user clicks on a JButton?

Question

My program is about a supermarket. I have created a JButton called b1 in the delivery() method. I want the JFrame window to close when the user presses the button b1. But unfortunately i do not know how to do that. Please help. Below is the delivery() method of my program:

public static void delivery()
{
    JFrame f = new JFrame("Name");
    f.setVisible(true);
    f.setSize(600,200);
    f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    f.setLocation(700,450);

    JPanel p = new JPanel();

    final JLabel l = new JLabel("Enter your name: ");

    final JTextField jt = new JTextField(20);

    JButton b1 = new JButton("Ok");
    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {
            input = jt.getText();
        }
    });

    p.add(b1);
    p.add(l);
    p.add(jt);
    f.add(p);

    String b = JOptionPane.showInputDialog(null, "Please enter your address in one single line:");
    JOptionPane.showMessageDialog(null, "The ordered stuff will be delivered to " +input+ " who lives in: " +b , "Delivery" , JOptionPane.PLAIN_MESSAGE);
    JOptionPane.showMessageDialog(null, "Thank you for shopping at Paradise 24/7. Hope to see you again." , "Shopping Done!" , JOptionPane.PLAIN_MESSAGE);
}

use JDialog instead of JFrame for popup window
with setModal, ModalityTypes to prevent Mouse and Keyboard events outside JDialog if is required
create only one istance of JDialog as local variable, setDefaultCloseOperations(HIDE_ON_CLOSE), then you'll use setVisible(true/false) for whole apllication life cycle

setVisible() should do the trick for ya

    public static void delivery()
{
    JFrame f = new JFrame("Name");
    f.setVisible(true);
    f.setSize(600,200);
    f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    f.setLocation(700,450);
    JPanel p = new JPanel();
    final JLabel l = new JLabel("Enter your name: ");
    final JTextField jt = new JTextField(20);
    JButton b1 = new JButton("Ok");
    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {
            input = jt.getText();
            f.setVisible(false);
        }
    });
    p.add(b1);
    p.add(l);
    p.add(jt);
    f.add(p);
    String b = JOptionPane.showInputDialog(null, "Please enter your address in one single line:");
    JOptionPane.showMessageDialog(null, "The ordered stuff will be delivered to " +input+ " who lives in: " +b , "Delivery" , JOptionPane.PLAIN_MESSAGE);
    JOptionPane.showMessageDialog(null, "Thank you for shopping at Paradise 24/7. Hope to see you again." , "Shopping Done!" , JOptionPane.PLAIN_MESSAGE);

simply call f.dispose() so you can close the JFrame
