Result Set error while working with jdbc, What does this error mean?

Question

Java

I receive an error message.
java.sql.SQLException: Before start of result set sql exception!
The cause of the error is not clear, can anyone explain?

String queryDataBase = "SELECT nickname,password,email FROM users  WHERE nickname = ? AND password = ? AND email = ?";


            PreparedStatement preparedStatement = connection.prepareStatement(queryDataBase);
            preparedStatement.setString(1, name);
            preparedStatement.setString(2, password);
            preparedStatement.setString(3, email);
            ResultSet resultSetQuery = preparedStatement.executeQuery();

            if (resultSetQuery != null){

                    if (resultSetQuery.getString("nickname").equals(name)) {
                        System.out.println(resultSetQuery.getString("nickname"));
                        if (resultSetQuery.getString("password").equals(password)) {
                            System.out.println(resultSetQuery.getString("password"));
                            if (resultSetQuery.getString("email").equals(email)) {
                                System.out.println(resultSetQuery.getString("email"));

Answer 1

Before fetching the data, try to call resultSetQuery.next(), the problem is that the cursor is before the first line, by calling this method you will move it to the first line.
