I have a small doubt regarding interfaces in sql package.
consider ResultSet interface or connection interface or any interface in java.sql
the methods in ResultSet are implemented and they are returning some values.
but generally methods in an interface are not having any definitions(must be abstract)
I want to know where and how these methods r given implementation
ResultSet is haaving a method next() which is pointing to the first record in the begining.
So some logic is given for that method next()
I want to know how and where this method next() is given implementation
plzz any body helpppppp?
THANKS IN ADVANCE
