How to use arrayList to store info from a JFrame and display it in a JOptionPane?

Question

My assignment requires me to use an arrayList to take the user selections of each order and display them in an Order Summary JOptionPane. Do I have to create a new class for the arrayList. We learned them without using GUIs so I am unsure on how to get it to display in the order summary for each order. For instance, if someone picked a sub type how would I get the type and price, store it in the arrayList, and display it in the order summary. If I was explained how to do one then I could figure out the rest.

EDITED

I tried to get the "toppings" the same way as the other options but it wouldn't work. How do you get this to work with a JCheckBox. Also, how do I do it for numbers to get the price? You can see in my code that I am trying a way with a case/switch. What am I doing wrong?

Thanks

`ArrayList ` is just a container (like ordinary array). For example, you can create a class `Order` and store objects of this class in your Arraylist. Then when required you will transfer string representations of your objects to JOptionPane. — PM 77-1, Aug 05 '13 at 00:17

You post a lot of codes, so, instead, I create a demo for you:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.List;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

/**
 *
 * @author Azad
 */
public class ShowListDemo extends JFrame implements ActionListener{
    private java.util.List<String> list;

    public ShowListDemo(){
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel p = new JPanel();
        JButton show = new JButton("Show List Content");
        show.addActionListener(this);
        p.add(show);

        list = new ArrayList<>();
        list.add("infromation one");
        list.add("information two");
        list.add("information three");

        add(p);
        setLocationRelativeTo(null);
        pack();
    }

    public static void main(String...args){
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
              new ShowListDemo().setVisible(true);
            }
        });
    }

    @Override
    public void actionPerformed(ActionEvent e) {
       String  s = "" ;
        for(String a : list)
            s += a +"\n";
        JOptionPane.showMessageDialog(this, s);//@Mad programmer's recommended, I can't refuse :)
    }
}

Also create a button for adding elements to the list, however, I prefer JList instead option pane, it's more comfortable.

I hope that means you're suggesting that the user should use a `JList` on the `JOptionPane`, cause that would be one of my suggestions ;) – MadProgrammer Aug 05 '13 at 00:27
@MadProgrammer: Actually I didn't mean that, but sounds good idea. – Azad Aug 05 '13 at 00:32
It's a nit-pick, but I would highly recommend that you pass `this` as the first parameter to `JOptionPane` as I can't abide dialogs that popup in relation to the component they were instantiated from - especially in a multi-screen environment :P – MadProgrammer Aug 05 '13 at 00:33

I think the use of a `JList` or `JTable` over the use of `JOptionPane` is also a good idea, but may be beyond the scope of what the OP is looking for – MadProgrammer Aug 05 '13 at 00:34
@MadProgrammer: I remmember I used this way in one of my assignments, till know I don't know why I get `0.8` on `3` :D – Azad Aug 05 '13 at 00:36
@MadProgrammer I'm supposed to use JOptionPane for the assignment but I don't think it is a requirement. – Kyle Aug 05 '13 at 01:25
@Kyle That's what I figured ;) – MadProgrammer Aug 05 '13 at 01:26

You could format the List of Strings as HTML and allow the HTML support in Swing to render it, something like Display array in JOptionPane, JOptionPane Multidimensional Array output and JOptionPane displaying HTML problems in Java for example

Something that many people forget, the second parameter to a JOptionPane is a Object, the JOptionPane allows you to pass a Component which it will use as it's primary display. This means you could display a JTable or JList for example.

Check out JOptionPane displaying HTML problems in Java for an example
