Я продолжаю получать эту ошибку, кто-нибудь может сказать мне, почему эта ошибка возникает или как я могу ее исправить, она почти уверена, что это ошибка соединения с базой данных, после того как я выполнил некоторый поиск, я обнаружил, что они изменили mysqlимя класса соединителя: com.mysql.jdbc.Driver в com.mysql.cj.jdbc.Driver, но я все еще использую старый соединитель, так почему я продолжаю получать эту ошибку.

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Я попытался изменить URL базы данных с convertToNull на CONVERT_TO_NULL, но возникает та же ошибка.Вот мой код подключения, и я просто отображаю содержимое базы данных в моей форме с помощью jTable в Netbeans 

public class MysqlConnection {
    public Connection con;
    /*public ResultSet rs;
    public Statement st;
    public PreparedStatement ps;
    public DataSource ds=null;*/
    public String User;
    public String Uid;
    public String Pwd;

    public String StrUrl="jdbc:mysql://localhost:50781/jayshreesteels?zeroDateTimeBehavior=CONVERT_TO_NULL";
    public String StrUid="root";
    public String StrPwd= "root";
    public static String StrUser;

    public static void main(String[] args) throws ClassNotFoundException, SQLException{
        String Url="jdbc:mysql://localhost:50781/jayshreesteels?zeroDateTimeBehavior=CONVERT_TO_NULL";
        Class.forName("com.mysql.cj.jdbc.Driver");
    }

    public MysqlConnection() throws SQLException {
        this.con = DriverManager.getConnection(StrUrl, "root", "root");
    }
}
