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.
You would usually close files immediately after reading or writing, but I see that log files would stay open until the JVM exits.
Can you list all open files?
What about a shutdown hook which starts a new thread to close all those files?
