This week's book giveaway is in the OCAJP forum. We're giving away four copies of Programmer's Guide to Java SE 8 Oracle Certified Associate (OCA) and have Khalid A Mughal & Rolf W Rasmussen on-line! See this thread for details.
Looking at their respective javadoc pages, it doesn't seem like they do anything similar ("The interface that every driver class must implement." vs. "The basic service for managing a set of JDBC drivers."). Can you elaborate why you think they do?
