creates an instance of this class and registers the DriverManager class when the instance is loaded. In this way, the user will not directly call DriverManager. registerDriver, but will be automatically called by the driver when loading the driver. There are two ways to load the Driver class and then automatically register in DriverManager:Call Class. forName. This will explicitly load the driver class.
