Updating database after cell selection (JTable)

Question

I want to update the value of the cell I've selected in JTable , which should reflect the database ( HSQL ) as button's listener is called upon.

JButton button = new JButton("VIEW AND EDIT");
button.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        int row = table.getSelectedRow();
        int column = table.getSelectedColumn();
        //(**********************)
        System.out.println(row + " : " + column);
        table.requestFocus();
    }
});

What piece of code should I replace with the * s?

PLEASE provide me with, either a sample code, or process to do the same.

My table has 4 columns with one PK .

If you want to update the table so it matches the current state of your DB, you should

• retrieve the current state from your DB on a worker thread
• create a new TableModel on the worker thread, and set it on the existing table on the Event Dispatch Thread OR
• update the existing table model on the Event Dispatch Thread

If you want to edit the values in the table, and push that state to your DB

• write/use a table editor
• when your TableModel receives the update (in the setValueAt method), push that state to the database on a worker thread
