这是我的代码

String url = "jdbc:mysql://sql210.lockernerd.co.uk:3306/";
String dbName = "lnw_18975270_test";
String driver = "com.mysql.jdbc.Driver";
String userName = "username";
String password = "pass"; 

        username = txtUsername.getText().toString();
        password1 = txtPassword.getText().toString();

        try {

            Class.forName(driver).newInstance();
            connection = DriverManager.getConnection(url + dbName, userName, password);
            String sql = "insert into test_table(id,name)values('" + username + "','" + password1 + "')";

            statement = connection.createStatement();
            statement.executeUpdate(sql);

当我运行我的项目时,我收到以下错误:
