Question

I need some help with a project that i have been set. I am creating a small addressbook program in java. I have got the user interface sorted and i am now working on adding information into a JTable from an inputDialog.

Here is my addressbook user Interface.

    import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JMenuBar;
import javax.swing.JMenu;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
import javax.swing.JPanel;

public class AddressBookGUI {

    private static final int FRAME_WIDTH = 400;
    private static final int FRAME_HEIGHT = 100;
    private static JTable table;

    public static void main(String[] args) {

        JFrame frame = new JFrame();
        final JFrame addPersonFrame = new JFrame();
        frame.setSize(768, 300);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //
        JButton addButton = new JButton("Add");
        addButton.setBounds(10, 228, 89, 23);
        addButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {

                JOptionPane.showInputDialog("First Name: ");
                JOptionPane.showInputDialog("Last Name: ");
                JOptionPane.showInputDialog("Address: ");
                JOptionPane.showInputDialog("Town: ");
                JOptionPane.showInputDialog("County: ");
                JOptionPane.showInputDialog("Post Code: ");
                JOptionPane.showInputDialog("Phone Number: ");

            }
        });
        frame.getContentPane().setLayout(null);
        frame.getContentPane().add(addButton);

        JButton editButton = new JButton("Edit");
        editButton.setBounds(109, 228, 89, 23);
        frame.getContentPane().add(editButton);

        JButton delButton = new JButton("Delete");
        delButton.setBounds(208, 228, 89, 23);
        frame.getContentPane().add(delButton);
        // Declare new menuBar and menuItems
        JMenuBar mainMenuBar = new JMenuBar();
        JMenu fileMenuBar = new javax.swing.JMenu();
        JMenuItem newFileMenuBar = new JMenuItem();
        JMenuItem openFileMenuBar = new JMenuItem();
        JMenuItem saveFileMenuBar = new JMenuItem();
        JMenuItem printFileMenuBar = new JMenuItem();
        JMenuItem quitFileMenuBar = new JMenuItem();
        JMenuItem editMenuBar = new JMenu();
        JMenuItem editPersonsEditMenuBar = new JMenuItem();
        JMenuItem sortNameEditMenuBar = new JMenuItem();
        JMenuItem sortPostcodeEditMenuBar = new JMenuItem();
        JMenuItem helpMenuBar = new JMenu();
        JMenuItem aboutHelpMenuBar = new JMenuItem();

        JMenuBar menuBar = new JMenuBar();
        menuBar.setBounds(0, 0, 742, 21);
        frame.getContentPane().add(menuBar);

        JMenu mnFile = new JMenu("File");
        menuBar.add(mnFile);
        // Declares and adds items to the menu
        JMenuItem menuItemNew = new JMenuItem("New");
        mnFile.add(menuItemNew);

        JMenuItem menuItemOpen = new JMenuItem("Open");
        mnFile.add(menuItemOpen);

        JMenuItem menuItemSave = new JMenuItem("Save");
        mnFile.add(menuItemSave);

        JMenuItem menuItemSaveAs = new JMenuItem("Save As..");
        mnFile.add(menuItemSaveAs);

        JMenuItem menuItemPrint = new JMenuItem("Print");
        mnFile.add(menuItemPrint);

        JMenuItem menuItemQuit = new JMenuItem("Quit");
        menuItemQuit.addActionListener(new exitApp());
        mnFile.add(menuItemQuit);

        JMenu menuEdit = new JMenu("Edit");
        menuBar.add(menuEdit);

        JMenuItem menuItemEditSelectedPerson = new JMenuItem(
                "Edit Selected Person");
        menuEdit.add(menuItemEditSelectedPerson);

        JMenuItem menuItemSortByName = new JMenuItem("Sort By Name");
        menuEdit.add(menuItemSortByName);

        JMenuItem menuItemSortPostCode = new JMenuItem("Sort By Post Code");
        menuEdit.add(menuItemSortPostCode);

        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setBounds(10, 32, 732, 151);
        frame.getContentPane().add(scrollPane);

        table = new JTable();
        table.setModel(new DefaultTableModel(new Object[][] {
                { "", null, "", "", "", null, null },
                { null, null, null, null, null, null, null },
                { null, null, null, null, null, null, null },
                { null, null, null, null, null, null, null },
                { null, null, null, null, null, null, null },
                { null, null, null, null, null, null, null }, }, new String[] {
                "First Name", "Last Name", "Addesss", "Town", "County",
                "Post Code", "Phone Number" }));
        scrollPane.setViewportView(table);

        frame.setVisible(true);

    }

    static class exitApp implements ActionListener {

        @Override
        public void actionPerformed(ActionEvent event) {
            // closes the application
            System.exit(0);

        }

    }

}

If some one could help me that would be great.

Thanks

If you need to pass the entered data from the JOptionPane to the JTable then first get the data and the UI and add it to the JTable.

If you are storing each row as an Object then use the method,

model.addRow(..);

If you are storing each value individually then use the method,

// value here is your input.
setValueAt(value, rowIndex, columnIndex);
