New value can be get from the DefaultCellEditor.

    button.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {

            if (table.getCellEditor() != null) {
                DefaultCellEditor cellEditor = (DefaultCellEditor) table.getCellEditor();
                String value = ((JTextField) cellEditor.getComponent()).getText();
            }

        }
    });

Action listener of your button. – rdonuk Apr 05 '16 at 14:47
I'm sorry, but I haven't create a Action listener and I don't understand how to do that.I'm very new to this – Nimesha Weerasinghe Apr 05 '16 at 14:52
My sample adding an action listener. Please try it. – rdonuk Apr 05 '16 at 14:55
Is it still returns the old value? – rdonuk Apr 05 '16 at 15:44

Maybe this solution will be sufficient for you:

table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);

It saves all table data not only when "save" button is clicked, but also in other cases of focus change.
