In jdbc api, most of the things defined are interfaces and not classes. Why most of them are interfaces?

Varma,
Welcome to JavaRanch!
JDBC uses interfaces because it only provides a contract for the classes. The actually implementation is provided by the JDBC driver. For example, if you use Oracle, you have a driver in the classes12.zip file. This file contains all of Oracle's custom classes that implement the JDBC interfaces.
