How can I create a data log, see every addition I made to my stock table, am using netbeans and xampp, and have 1 table. Which is stock

This is just part of the code as am new here and don't know exactly what to do. Just need to add data logs to my panel in netbeans so I can see all new updates I made going to product table that have column "stock". Will need to include data if possible time toenter image description here. Need help.

Am a novice as well. private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// SAVE PRODUCT

    String name = p_name.getText();
   
    String qty = p_qty.getText();
   
    
    
    try {
        
        Statement s = db.mycon().createStatement();
        //`pid`, `Product_Name`, `Bar_code`, `Price`, `Qty`, `Sid`
        s.executeUpdate("INSERT INTO product (Product_Name,Qty) VALUES('"+name+"','"+qty+"')");
        JOptionPane.showMessageDialog(null, "Data Saved");
        
    } catch (SQLException e) {
        System.out.println(e);
    }
