URGENT - How to change data in a table

Question

I have created the basic table to display some data. But how do I change some of the data in the table. I generate the data within my program and then need to display the new table data in the same original table.

Answer 1

So far I am just testing with the example codes from the sun website. How would I change the name Mary to say Kate? Do I have to implement an abstract table model? Can I just change the value in the array or something?
Thanks in advance
// create the table
               Object[][] tableData =
            {"Mary", "Campione",
             "Snowboarding", new Integer(5), new Boolean(false)},
            {"Alison", "Huml",
             "Rowing", new Integer(3), new Boolean(true)},
            {"Kathy", "Walrath",
             "Chasing toddlers", new Integer(2), new Boolean(false)},
            {"Mark", "Andrews",
             "Speed reading", new Integer(20), new Boolean(true)},
            {"Angela", "Lih",
             "Teaching high school", new Integer(4), new Boolean(false)}
          String[] columnNames = {"First Name",
                                "Last Name",
                                "Sport",
                                "# of Years",
                                "Vegetarian"};
          final JTable table = new JTable(tableData, columnNames);
        table.setPreferredScrollableViewportSize(new Dimension(500, 100));
          //Create the scroll pane and add the table to it.
        JScrollPane scrollPane = new JScrollPane(table);
          //Add the scroll pane to this window.
        //getContentPane().add(scrollPane, BorderLayout.CENTER);
          displayPanel.add(scrollPane);
