Java 6 comes with SwingWorker as an integral part of the JRE (yes, you no more need to download it). And THAT version of SwingWorker can send progress status while the background work still is in progress. Using this new feature, it is possible to do a lengthy background operation that reports its status from time to time. For example: While loading thousands of rows from the server (which might...

Attaching a GUI to a domain model object (a.k.a. "Entity") is a boring job. You need to write lots of synchronization code or models to change the UI when the entity changes and vice versa. Now that has an end. Here is the ultimate, automatic glue generator: The Java Beans Binding API. It allows you to glue together two Java Beans (i. e. POJOs, and has nothing to do with Swing or EJB)....

Do you know EnumSet? No? Then you should take the time to look at this sample code. EnumSet allows writing of really eloquent Java source code. Run the following code and watch its result printed on the screen. Then check the below source code to find out how it works. The source code particulary makes use of (at least) the following features introduced in Java 5: enum keyword The enum keyword...

The next edition of my CS1/Java book is going to print soon. At the last minute, we decided to put the real estate of the inside covers to good use and include a “cheat sheet” with the most important Java control structures and libraries. Since it would be particularly embarrassing to have a typo here, I am hoping to enlist the aid of the community. PDFs for the inside covers are...

Programming

Several APIs demand that the user is implementing the .hashCode() method. The reason is that these APIs are using hash based containers (like HashMap) to have a fast means of managing lots of objects (always comparing objects using .equals() would need endless time). There are lots of standard implementations on the web, so the question is, what performance impact the implemenation of .hashCode...

Testing

As the year draws to a close, I wanted to give everyone a heads-up about some of the Wakaleo training sessions already lined up for 2010. The next big training dates are in Europe - in collaboration with Skills Matter, I will be running the Java Power Tools Bootcamp in London (February 15-19) and Paris (February 22-27), and then in Wellington in March (March 22-26). I'm also lining up sessions...

Databases

The W3C Social Web Incubator Group is organizing a free Bar Camp in the Santa Clara Sun Campus on November 2nd to foster a wide ranging discussion on the issues required to build the global Social Web. Imagine a world where everybody could participate easily in a distributed yet secure Social Web. In such a world every one will be able to control their own information, and every business would...
