Closing Database Connections in Java

Question

I am getting a little confused, I was reading the below from http://en.wikipedia.org/wiki/Java_Database_Connectivity

Connection conn = DriverManager.getConn         


        

Answer 1

It is enough to close just Statement and Connection. There is no need to explicitly close the ResultSet object.

Java documentation says about java.sql.ResultSet:

A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.

Thanks BalusC for comments: "I wouldn't rely on that. Some JDBC drivers fail on that."
