    Default Super Bowl Tickets

    So, I am in a Java Programming Intro class, and for whatever reason I am just stuck on our final project. Basically I need this to work. It looks exactly as it should so far. We are supposed to use the actionPerformed method to make it work, and make the results show up on a new window, and it's supposed to look like this;

    Event: Super Bowl 2011
    Issued to: <Name>
    Quantity: <NumberOfTickets>
    Section: <Whicheveronetheychose>
    Ticket Charge: $<Calculated Value>
    Delivery Charge: $<10 or zero>
    Total Charged: $<Calculated Value>

    Here is what I have so far;

    public class TicketApp extends JApplet
    {
        private int x;
     
        JLabel sbtLabel;
        JLabel name;
        JLabel tickets;
        JLabel section;
     
        JTextField nametext;
        JTextField tickettext;
        JComboBox sectionbox;
        JCheckBox express;
        JButton submit;
     
        public void init()
        {
            setLayout( new FlowLayout(FlowLayout.LEFT));
            sbtLabel = new JLabel("<HTML><FONT SIZE=+1>Super Bowl Tickets 2011</FONT>");
            name = new JLabel("<HTML>Enter Name");
            nametext = new JTextField(12);
            tickets = new JLabel("<HTML>Number of Tickets");
            tickettext = new JTextField(4);
            section = new JLabel("<HTML>Choose a Section");
            sectionbox = new JComboBox();
            sectionbox.addItem ("Club Box ($400)");
            sectionbox.addItem ("Lower Deck ($200)");
            sectionbox.addItem ("Upper Deck ($150)");
            express = new JCheckBox("Express Delivery? (add $10)");
            submit = new JButton("Submit Order");
     
            add (sbtLabel);
            add (name);
            add (nametext);
            add (tickets);
            add (tickettext);
            add (section);
            add (sectionbox);
            add (express);
            add (submit);
     
     
        }
    So yeah, any help is greatly appreciated.

    Thanks,
    Jonathan Oty

    the way i would do it is put a series of if statements in the actionperformed method:

    public void actionPerformed(ActionEvent e)
    {
    String mystr = new String("");
     
    if(e.getsource==nametext)
    {
    mystr = nametext.getText();
    // then have another class called to open a frame with a windowListener to close it when the x is clicked
    }
     
    // do with the other textboxes via 'else if'
    }

    i hope you get the jist of what im getting at

    What exactly is the question? Just mentioning you are stuck does not give us much information to point you in the right direction. See the following tutorial for how to use ActionListeners: How to Write an Action Listener

    Well thanks both of you for the help, I didn't really have any specific questions I was just lost, but I worked through most of it. The program isn't very pretty, but I'm ok with it, now my last question is how to properly format the message windows with each piece of info on a separate line. If i could figure that out I would be greatly appreciative.

    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;

    public class TicketApp extends JApplet
    implements ActionListener
    {
    JLabel sbtLabel, name, tickets, section;
    JTextField nametext;
    JTextField tickettext;
    JComboBox sectionbox;
    JCheckBox express;
    JButton submit;
    int a;

    public void init()
    {
    setLayout( new FlowLayout(FlowLayout.LEFT));
    sbtLabel = new JLabel("<HTML><FONT SIZE=+1>Super Bowl Tickets 2011</FONT>");
    name = new JLabel("<HTML>Enter Name");
    nametext = new JTextField(12);
    tickets = new JLabel("<HTML>Number of Tickets");
    tickettext = new JTextField(4);
    section = new JLabel("<HTML>Choose a Section");
    sectionbox = new JComboBox();
    sectionbox.addItem ("Club Box ($400)");
    sectionbox.addItem ("Lower Deck ($200)");
    sectionbox.addItem ("Upper Deck ($150)");
    express = new JCheckBox("Express Delivery? (add $10)");
    submit = new JButton("Submit Order");
    submit.addActionListener( this );

    add (sbtLabel);
    add (name);
    add (nametext);
    add (tickets);
    add (tickettext);
    add (section);
    add (sectionbox);
    add (express);
    add (submit);



    }
    public void actionPerformed( ActionEvent ae )
    {
    Object obj = ae.getSource( );
    String name = nametext.getText();
    String ticket = tickettext.getText();
    int n = Integer.parseInt(ticket);
    int selectedOutput = sectionbox.getSelectedIndex();
    boolean checked = express.isSelected();
    int a, b, c, d, e, f;

    a = 400 * n;
    b = 400 * n + 10;
    c = 200 * n;
    d = 200 * n + 10;
    e = 150 * n;
    f = 150 * n + 10;

    String message;
    if ( selectedOutput == 0)
    if ( checked == false )
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Club Box ($400)" + "Ticket Charge: $" + a +
    "Delivery Charge: $0" + "Total Charged: $" + a);
    else
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Club Box ($400)" + "Ticket Charge: $" + a +
    "Delivery Charge: $10" + "Total Charged: $" + b);
    else if ( selectedOutput == 1)
    if ( checked == false )
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Lower Deck ($200)" + "Ticket Charge: $" + c +
    "Delivery Charge: $0" + "Total Charged: $" + c);
    else
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Lower Deck ($200)" + "Ticket Charge: $" + c +
    "Delivery Charge: $10" + "Total Charged: $" + d);
    else
    if ( checked == false )
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Upper Deck ($150)" + "Ticket Charge: $" + e +
    "Delivery Charge: $0" + "Total Charged: $" + e);
    else
    message = ("Event: Super Bowl 2011" + "Issued to: " + name +
    "Quantity: " + ticket + "Section: Upper Deck ($150)" + "Ticket Charge: $" + e +
    "Delivery Charge: $10" + "Total Charged: $" + f);

    JOptionPane.showMessageDialog( null, message, "Message Window",
    JOptionPane.PLAIN_MESSAGE);



    }
    }
