The whole part of the Big Red ish regular launch plan instead of major infrequent updates

Shindig … The Oracle Code One conference began today

Code One Oracle announced on Monday the launch of Java SE 13 (JDK 13), saying it shows the continuing commitment of the technology titan to make innovation faster by sticking to a predictable launch cycle of six months.

There was no evidence provided to demonstrate that business innovation is actually accelerating as a result of the biannual reviews of the platform. Oracle at least deserves credit for its commitment to consistency.

The news of JDK 13 came on Monday when Oracle's OpenWorld and Code One code share conferences began in San Francisco. The keynote of Code One, preceded as in previous years with a disclaimer that investors should not rely on anything said at the fair, opened with an overview of quantum computing by Jessica Pointing, a PhD student in quantum computing at Stanford University.

What does quantum computing have to do with Java? Well, Pointing said developers can write code for Strange Quantum Computer Simulator in Java.

The challenge for quantum computing at this time, he explained, is to demonstrate that a quantum computer can outperform a classical computer to solve specific types of problems. Surprisingly, despite some investment, that has not yet happened. It could happen in the coming months. Or it may take a few years. Or decades.

Looking back a few years before 2017, Georges Saab, software development expert for the Java platform, recalled the decision to change the Java launch cadence, noting that large releases every few years showed disadvantages as The world embraced more rapid change.

The Oracle Java team changed to a six-month release rate two years ago because the wait for three or four years between major releases is no longer done, for the most part. C ++ still adheres to a three-year update cycle, but that seems icy compared to ECMAScript annual improvements, Node.js revisions twice a year and Chrome browser versions that appear every six weeks.

"Three of these releases have since been delivered and the fourth is imminent "Saab said. "We are proud to announce Java 13 with general availability starting tomorrow."

Binaries for JDK 13 are expected to be available for download on Tuesday, September 17.

Saab proceeded to interview several developers who use Java in several companies to reveal that they are happy with the fastest launch cycle. As expected, no detractors appeared.

Java, insists Oracle, is the most popular programming language in the world; IT consultant RedMonk ranks Java in number two, behind JavaScript. But such measurements say more about statistical methodology and data sources than verifiable popularity. Suffice it to say that Java is widely used among large and small companies, and remains an employable competition.

Notable preview features at launch include change expressions (JEP 354), which extends the change statement so that it can be used as a statement or as an expression, and blocks of text, which provide a concise form of represent multi-line text strings without escape characters (JEP 355).

"It's not a particularly sophisticated feature but it makes a big difference," said Brian Goetz, Java launch architect.

Preview features can be changed or deleted, and are provided to request comments from the community.

JDK 13 includes several other JEPs (Java improvement proposals). JEP 350 extends the sharing of application class data to improve startup and memory footprint. JEP 351 modifies Z Garbage Collection (ZGC) so that it returns the memory of the unused heap to the operating system. And JEP 353 replaces the old API Socket and ServerSocket with a more modern code that is easier to maintain. Also lay the foundation for user mode threads, known as fibers.

Goetz acknowledged that there are not many important features because they are now being divided into smaller ones to accommodate more frequent updates. "There is so much innovation, maybe more, but it will be divided into a series of smaller releases," he said. ®
