How can I refresh a data in JTable

[Dexter]

I found a bit of code that solved my initial problem that was to
display two dimensional array data in a JTable. How can I change this
code if I want to display new data in a JTable which is showing the
data initially assigned to it.

Say the table was showing

Field 1 Field 2
USA D.C
UK London

And now that the program is running I want new data to be showing from
a 2 dimensional array

Field 1 Field 2
Aus Canberra
Ireland Dublin

This is the code snippet that helped me create the initial JTable

Thanks

Container contentPane = frame.getContentPane();
String headers[] = {"Leader", "Country"};
String data[][] = {
{"Tony Blair", "England"},
{"Thabo Mbeki", "South Africa"},
{"Megawati Soekarnoputri", "Indonesia"},
{"Hosni Mubarak", "Egypt"},
{"Vladimir Putin", "Russia"},
{"Vicente Fox", "Mexico"},
{"Ariel Sharon", "Israel"}
};
TableModel model =
new DefaultTableModel(data, headers) {
// Make read-only
public boolean isCellEditable(int x, int y) {
return false;
}
};
JTable table = new JTable(model);
// Set selection to first row
ListSelectionModel selectionModel =
table.getSelectionModel();
selectionModel.setSelectionInterval(0, 0);
selectionModel.setSelectionMode(
ListSelectionModel.SINGLE_SELECTION);
// Add to screen so scrollable
JScrollPane scrollPane = new JScrollPane (table);
contentPane.add(scrollPane, BorderLayout.CENTER);

Implement a class implementing
http://java.sun.com/javase/6/docs/api/index.html?javax/swing/table/AbstractTableModel.html
instead of using an array.


If you use an array, java builds an internal table model. If you
change the array then the model doesn't change. That's why you need a
own class implementing a table model.

have a look at the code for Vercheck.

or http://mindprod.com/products1.html#VERCHECK to download it.

Basically, you lock the row, update your data in the ordinary way,
then trigger an event to let the GUI know what has changed.

Thanks very much for your hints.
I finally got the code working with help from sources both you
mentioned.

I needed the code to work with a mortgage calculator that refreshed
the amortization schedule for new calculations. Its working now. No I
am not going to post the link as in past I been referred to by many
funny titles when doing so.

Thanks once again.
