JTable > how to display the database to automatically based on time

Dear All,

I have made a program to display data from a database using netbeans. In the netbeans I created a JFrame Form. Here's a snippet of code that I created:

===============

Java Code:

public class Back extends javax.swing.JFrame {

    public Back() {
        initComponents();
        
        loadDataPrefix();
       
    }

....................

    public void loadDataPrefix(){
        DefaultTableModel dtmPrefix = new DefaultTableModel();
        dtmPrefix.addColumn("Id");
        dtmPrefix.addColumn("Operator");
        dtmPrefix.addColumn("Prefix");
        try {
            String queryPrefix = "SELECT * FROM prefix ORDER BY prefix_name";
            statementPrefix = connection.createStatement();
            resultSetPrefix = statementPrefix.executeQuery(queryPrefix);
            int size = 0;
            while(resultSetPrefix.next()){
                size++;
                dtmPrefix.addRow(new Object[]{
                    size,
                    resultSetPrefix.getString(3),
                    resultSetPrefix.getString(2)
                });
                jTable4.setModel(dtmPrefix);
            }
        } catch (SQLException preEr) {
            JOptionPane.showMessageDialog(null, preEr,"Peringatan !",JOptionPane.WARNING_MESSAGE);
        }
    }
......................
}

===============

I created a button to update the database in JTable display as follows:







===============

Java Code:

private void jButton8ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        // TODO add your handling code here:
        loadDataPrefix();
}

===============







Everything went as desired.

What I need is to make a checkbox, which when select the checkbox in JTable will display data based on the data that is in my mySQL database automatically.

For example, when I enter data or edit data to MySQL (via DOS or phpmyadmin or other applications) then changes to a JTable data is displayed automatically.

And when chexkBox not select it to display the database changes have to click a button.

Kindly enlighten and sample code completion. Thank you ....
