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.
 
It is sorta covered in the JavaRanch Style Guide.
