Hi,

Its because of each DB is vendor specific.So the class that provides you a connection object implements the Connection interface(Polymorphism).

Connection con=DriverManager.getConnection(<params>);

DriverManager.getConnection(<params>); return the object of a class(the name of a class does not matter) that implements the Connection interface

Hope this helps
Thanks


The important thing is not to stop questioning.Curiosity has its own reason for existing.
