This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
As a reference the javadocs are very useful. If you're looking for examples and introductions, check out The Java Almanac for JDK 1.4, and "Java in a Nutshell", "Java Examples in a Nutshell" and "Java Enterprise in a Nutshell" from O'Reilly. [ May 11, 2006: Message edited by: Ulf Dittmer ]
