Brian Goetz recently provided new details on the status of JSR 335 in his OpenJDK document "State of the Lambda: Libraries Edition." Project Lambda is a fundamentally important enhancement to Java 8. And, based on the response of developers in our recent poll...
Recently, I've been investigating the methods Java provides for developing desktop applications that efficiently utilize multicore processors. Java 7's Fork/Join Framework is the current focus of my investigation. But, Brian Goetz has just provided an update on the "State of the Lambda: Libraries Edition," which tells us lots about the current status of what's coming up in Java 8...
A few nights ago, I was browsing the chapters about concurrent programming in Herbert Schildt's excellent "Java: The Complete Reference, 8th Edition," and I was struck by the evolution of concurrency in Java over the years, from threads, through the richness of Java 5's Concurrency Utilities, and on to Java 7's Fork/Join Framework...
With the advent of multicore processors on everything from desktop computers to tablets, pads, and even mobile phones, parallel processing is gaining increasing attention. This is at least in part what's behind the release of the Fork/Join Framework in Java 7, and the inclusion of Lambda Expressions...
Note to the Java 8 development team (and the JCP): the latest completed Java.net poll indicates that Java developers overwhelmingly advocate the inclusion of JSR 310 in Java 8. Not only did the poll draw a large volume of voting, but the votes were unusually strongly skewed...
In my previous blog post, I did some experimentation with simultaneous execution of multiple threads. Since the threads were all doing relatively large chunks of work, the overhead from thread creation and management was almost irrelevant. In this post, I take a look at the overhead that launching a series of threads...
Our lead Java Today story is "JAX-RS with Jersey: An Introduction," by Dustin Marx. I found this intersting, because a few weeks ago I spent some time studing Jersey, as I thought about resurrecting an old project of mine...

"The multicore challenge" is the challenge to developers of software products to write code that effectively utilizes modern multi-core / multi-processor computers. Two years ago, I wondered if the multicore challenge was still relevant. In part, I was thinking about how applications were moving from the desktop into the cloud. So, if the apps people are running are running in a browser, does it matter if their desktop system (or pad or phone) is multicore?...

This is the first edition of a new column I'll be writing each weekend titled "Java.net: the Week in Review." In the column, I'll present all of the previous week's Java Today news items, a selection of java.net blog posts, polls, and spotlights...
