The DriverManager class acts as an interface between user and drivers. It keeps track of the drivers that are available and handles establishing a connection between a database and the appropriate driver. The DriverManager class maintains a list of Driver classes that have registered themselves by calling the method DriverManager.registerDriver().
|1) public static void registerDriver(Driver driver):|| is used to register the given driver with DriverManager.|
|2) public static void deregisterDriver(Driver driver):|| is used to deregister the given driver (drop the driver from the list) with DriverManager.|
|3) public static Connection getConnection(String url):|| is used to establish the connection with the specified url.|
|4) public static Connection getConnection(String url,String userName,String password):|| is used to establish the connection with the specified url, username and password.|
