It’s always important to keep your software updated with the latest patches. This is especially true with Java because so many hackers target even the smallest weaknesses. According to a recent ComputerWorld article, Java 7 has reached the end of its public life for updates. You need to upgrade to Java 8 in order to continue receiving free updates from Oracle. The rapid pace of updates that vendors rely on now is made necessary by hackers who apparently create malware updates even faster. Even at the fast release pace that Oracle is using, the malware just keeps rolling out. In other words, as a developer you need to exercise proactive coding to keep security risks at bay, in addition to relying on Oracle and other vendors for help.
A number of people have asked me about updates to Java eLearning Kit for Dummies. As far as I know, the publisher currently doesn’t have plans for an update. Of course, that could change at some point. Until the next update, however, the examples I’ve tested with Java 8 work fine on a Windows system. I’ll be performing additional testing on both OS X and Linux. However, I don’t have quite the number of people testing the book code as I had when I wrote it. If anyone does encounter a problem with the code, I’d greatly appreciate hearing about it at John@JohnMuellerBooks.com. I can’t guarantee that I’ll be able to fix absolutely every issue, but I’ll try to find workarounds and publish them on the blog for you.
As always, please don’t send me your personal code—I only work with book-specific code. Using the downloadable source is always the best way to get the most you can from a book. I’ve also created the Using My Coding Books Effectively post to help you get the most from my books. It’s important to me that you get the most you can from my books.
