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.
I've coded in Java for a few semesters now, but not in any of my classes has a hash table or hash set/maps come up. I see people using them in their source code they post on this forum, but i'm not really sure what they do that's better than ways i code. So i was wondering if someone could fill me in on their uses and functionality.
