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 just read the book's description on Amazon. It mentions that you used a Web crawler as an example. Is a Web crawler the kind of thing that Google uses to index pages? What does the Web crawler example in the book do?
