    Default no account in my database[java interface login]

    Good evening, folks,
    I'm a beginner in java and I'm creating an interface
    connection with the netbeans ide software.
    I would also like to link it with a local database with wampserver
    The problem is that when I write the code, everything is nicquel but
    When I create the account, I get the message register successfully
    but in the database nothing appears, please, I have the impression
    for screwing up somewhere. my code:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
            try{
                String query= "INSERT INTO `user`(`name`, `surname`, `email`, `plan`, `password`, `phone`) VALUES (?, ?, ?, ?, ?, ?)";
                con = DriverManager.getConnection("jdbc:mysql://localhost/userregistration", "root", "");
                pst = con.prepareStatement(query);
                pst.setString(1, txtName.getText());
                pst.setString(2, txtSurname.getText());
                pst.setString(3, txtEmail.getText());
                pst.setString(4, cmbPlan.getSelectedItem().toString());
                pst.setString(5, txtPass.getText());
                pst.setString(6, txtPhone.getText());
                pst.executeUpdate();
                JOptionPane.showMessageDialog(null, "REGISTER SUCCESSFULLY");
     
            }catch (Exception ex) {
                JOptionPane.showMessageDialog(null, "REGISTER SUCCESSFULLY");
            }
        }

    And also without having put the information in the fields
    when I click on "register" I also get the message "register sucessfully"
    Thank you for helping me
    I have attached the images to my post and the code is highlighted in yellow.

    The two messages appear to have the same text.
    Also add a call to printStackTrace to the catch block to get the full text of any error message.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    Thank you
    I don't understand well when you ask me to use the printStack trace?

    printStackTrace is a method in the Throwable class (parent of Exception) that will print out the contents of the error message and the call stack for where the execution flow was.
    It should always be called in a catch block to show what and where about the exception.
           }catch (Exception ex) {
                ex.printStackTrace();
                JOptionPane.showMessageDialog(null, "REGISTER NOT SUCCESSFUL");
            }

    I just added, but the problem hasn't changed. Now I have the message
    "register not successfully". It's like my code is running in a loop.

    Can you copy the full text of the error message and paste it here? It will have info about the problem.
