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.
Java Practice Questions: Oracle Certified Associate, Java SE 7 Programmer This is a book with 120 practice questions (15 questions for each objective of the exam) with detailed explanations for the Oracle Certified Associate Java SE 7 Programmer (IZ0-803) certification.
I wrote it for the Amazon Kindle plataform because of the low costs of publishing and to make it available to a greater number of people.
It normally costs $5.99 USD, but for Jan 22 12:00 PST to Jan 26 11:59 PST it will be free, so if you are thinking about getting certified as an OCAJ, this is a good chance to practice and test your knowledge.
If you download it, please give me some feedback, I am writing questions for the other Java certification exams also.
