This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
This forum, which doesn't require you to log in, is for discussing JavaRanch itself -- for example, "Help, I forgot my password and can't log in!" Technical questions belong in the other forums, which do require you to register, using a valid display name with a first name and a last name separated by a space.
