Answer 1

You can do something likewise,

String sql = "UPDATE LOGIN SET USERNAME = ?, PASSWORD = ?, NAME = ? WHERE USERNAME = ?" 

PreparedStatement preparedStatement = dbConnection.prepareStatement(sql);
preparedStatement .setString(1, UsernameText4.getText());
preparedStatement .setString(2, PasswordText4.getText());
preparedStatement .setString(3, NameText4.getText());
preparedStatement .setString(4, jLabel16.getText());

preparedStatement .executeUpdate();
....
dbConnection.commit();
