java.sql.SQLException: null, message from server: "Host 'xxx' is not allowed to connect to this MySQL server"

I am currently trying to access mySQL-database through a Java Application. In order to do so, I downloaded the "mysql-connector-java-5.1.42-bin.jar" file and imported it to Eclipse Neon.3. My MySQL Server is up and running as following screenshot Shows:

I have tried it with following code:

final private String user = "root";
final private String passwd = "root";

public void connectToDB() throws Exception {
  try {
    // This will load the MySQL driver, each DB has its own driver
    Class.forName("com.mysql.jdbc.Driver");
    String url= "jdbc:mysql://xxx:3306/pilotproject";                

    // Setup the connection with the DB
    connect = DriverManager.getConnection(url, user, passwd);
    System.out.println("Database connection established"); 
  {
{

but I am getting following error:
