Hi Friends,
I have a small query worth mentioning in this forumn.

We all know Connection (java.sql) is an interface. Then how can we call a method like close() on an interface reference. I mean where are these methods being referred from..Any1 knowing the reason for the same kindly help me...


Thanks & Regards,
Nischal

We can do this because we are actually calling a method against the interface implementation not the interface direct. The implementation of the Connection interface is part of the JDBC driver you are using.
