Hi Dhiraj,
String connectionURL = "jdbc:mysql://localhost:3306/learn?user=root;password=";
Connection connection = DriverManager.getConnection(connectionURL, "root", "");
It seems to be your trying to pass twice of your properties details. One from through URL and another from by pasing the parameters on getConnection() method. Better to avoid to use two place in same application. and one more thing I want to confirm r u using "stable" Driver or "alpha" Driver.
