java netbeans新的驱动程序类是`com.mysql.cj.jdbc.Driver'。

Question

I keep on getting this error, can anybody tell me why this error occurs or how can i resolve it, its pretty much sure that its the database connection error, after i did some search, i Found the that they changed the mysql-connector class name: com.mysql.jdbc.Driver to com.mysql.cj.jdbc.Driver, but Im still using the old connector so why do i keep getting this error.

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.

I tried changing my url of database from convertToNull to CONVERT_TO_NULL but the same error occurs. Here is my connection code & im just displaying the contents of database in my form with the help of jTable in 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");
    }
}
