- JSR 310: A New Java Date/Time API by Jesse Farnham - [Clicks: 4]
Java SE's Date and Calendar classes leave much to be desired. Will the third time be the charm? JSR 310, tracking for inclusion in Java SE 7, once again tries to offer a comprehensive date and time API, borrowing much of its design from the popular Joda Time API. In this article, Jesse Farnham takes a look at JSR 310's concepts and how they may yet bring sense to dates and times in Java.

Newer JVM-compatible languages like Scala, Groovy, and JRuby are better suited to creating internal DSLs than the Java language itself. Find out why in this final article in Venkat Subramaniam's introduction to creating DSLs in Java.

Annotations were introduced in Java 5, and now that the community has had time to try them out and get used to them, Java 7 is preparing to adopt them aggressively. In this installment of The Open Road, Elliotte Rusty Harold looks at the annotations proposed by JSR 305 and how they'll make your code more amenable to static analysis, compiler checks, and other tools to improve safety and robustness.

Start with a Java applet and build a server-based proxy system that uses your browser to access an arbitrary Web service. You'll use JavaScript code to access applet-based information and call a servlet, which retrieves the remote information. Thus, you bypass the same-server restrictions on what an applet can and cannot do.

This article explains how you can improve the performance of I/O-intensive Java applications running on Linux and UNIX platforms through a technique called zero copy. Zero copy lets you avoid redundant data copies between intermediate buffers and reduces the number of context switches between user space and kernel space.

Overloaded method names must differ by parameter count and type and not return type, right? Wrong! The VM knows the return type of all methods and with a little bytecode engineering, you can have methods that differ only by return type. Vinit Joglekar shows you how it's done.

With the recent reports of Java's imminent demise, you're probably wondering if it's time to leave the platform behind for greener pastures. Before you make a decision, step back and examine the Java ecosystem, along with that of its competitors, to see if the rumors have any substance. It's time, in other words, to have a State of the Java Union address, holding neither pride nor prejudice in the evaluation of the platform.

Wonder what the relationship between com.example.package and com.example.package.test is? There isn't one! This lack of an orderly package-visibility relationship has made life difficult for a number of programmers trying to balance organizational needs against practical concerns. In this entry of "The Open Road," Elliotte Rusty Harold takes a look at how JSR 294 ("superpackages"), intended to be part of Java SE 7, proposes to fix this problem.

One of the additions to the java.util.concurrent packages coming in Java 7 is a library for fork-join-style parallel decomposition. In part one of this series, author Brian Goetz showed how fork-join provides a natural mechanism for decomposing many algorithms to effectively exploit hardware parallelism. In this article, he'll cover the ParallelArray classes, which simplify parallel sorting and searching operations on in-memory data structures.
