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().

Commonly used methods of DriverManager class:

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.
