By Paul Krill Java Development Kit (JDK) 23, the next planned version of standard Java, is off and running, with five features now scheduled for the release. The latest addition is making the generational mode of the Z Garbage Collector the default mode. Due September 17, JDK 23 also will include a vector API, which will be incubated for the eighth time, a second preview of stream gatherers, a second preview of a class-file API, and a preview of primitive types in patterns, instanceof, and switch. Early access builds for JDK 23 can be accessed from jdk.java.net. Added this week is a plan to sw...

By Paul Krill The readability, maintainability, and usability of switch statements and expressions in Java would be improved by a proposal to allow exceptions to be handled in the switch block. The current OpenJDK proposal, “Exception handling in switch (Preview),” would be part of the Standard Edition of Java, although no specific version Java SE has been designated yet as the recipient. Specifically, the proposal calls for enhancing switch so that exceptions thrown by the selector (the e in switch (e) …) can be handled in the switch block. Goals of the plan, which was created January 12 and ...

By Paul Krill Java would be enhanced with the ability to succinctly import all packages exported by a module, under a proposal floating in the Java community. The plan would simplify the use of modular libraries in Java. The preview language feature for Java SE (Standard Edition), called Module Import Declarations, has been filed as a JDK Enhancement Proposal (JEP) in the OpenJDK community. Goals of the plan include simplifying the reuse of modular libraries by allowing entire modules to be imported at once, avoiding the noise of multiple type-import-on-demand declarations when using diverse p...

By Paul Krill ECMAScript 2024, a planned update to ECMA’s standard for JavaScript, is set to include seven new features ranging from array grouping to Unicode strings. The 2024 specification, from ECMA’s Technical Committee 39, is expected to be approved in June. Among the list of finished features cited for publication this year is a proposal for array grouping. Motivating this proposal is the notion that array grouping is a common operation best exemplified by SQL’s GROUP BY clause and mapreduce programming. The ability to combine like data into groups lets developers compute higher order da...

By Paul Krill Parasoft has launched a tool to enhance safety testing for C and C++ applications. The tool comes at a time when the two venerable programming languages have come under fire over safety concerns. Announced April 8, the C/C++test CT (Continous Testing) tool is intended to empower large developer teams to build reliable and dependable embedded systems. It provides a comprehensive solution for large teams engaged in the development of safety-critical and security-critical C and C++ products, Parasoft said. C/C++test CT integrates with developers’ desktop environments such as Visual ...

By Paul Krill PHP, long a popular server-side scripting language for web development, has dropped to its lowest position ever in the monthly Tiobe index of programming language popularity, ranking 17th in the April 2024 edition of the index. When the Tiobe index started in 2001, PHP was about to become the standard language for building websites, said Paul Jansen, CEO of software quality services vendor Tiobe. PHP even reached the top 3 spot in the index, ranking third several times between 2006 and 2010. But as competing web development frameworks such as Ruby on Rails, Django, and React arri...

By Chathura Ekanayake Many business processes involve communicating with external parties such as suppliers, logistics providers, insurance providers, and government institutions. Unlike internal communications, these inter-organizational communications usually have to follow various regulations and standards, and could introduce delays if one party doesn’t comply. Therefore, effective business-to-business (B2B) integrations are a key part of most digital transformation projects. Let’s take the fictional example of an electronic equipment manufacturer named Smartware. Smartware supplies equipm...

By Serdar Yegulalp Over the past decade, Rust has emerged as a language of choice for people who want to write fast, machine-native software that also has strong guarantees for memory safety. Other languages, like C, may run fast and close to the metal, but they lack the language features to ensure program memory is allocated and disposed of properly. As noted recently by the White House Office of the National Cyber Director, these shortcomings enable software insecurities and exploits with costly real-world consequences. Languages like Rust, which put memory safety first, are getting more att...

By Simon Ritter With atomic clock-like regularity, the latest version of Java, JDK 22, was released last week. Although this is not a long-term support (LTS) release, there is nothing to stop you from using it in production, and it contains some interesting new features. Let’s dive in and see what this brings us. New features for the Java platform are defined through JDK Enhancement Proposals (JEPs), and JDK 22 contains 12 of these. Coincidentally, over the last 13 Java releases, since the switch to a six-month cadence, the average number of JEPs (to the nearest integer) is also 12. You could,...

By Paul Krill To reduce application execution time, Java’s segmented code cache would be extended with an optional “hot” code heap to compactly accommodate a part of non-profiled methods, under a draft JDK enhancement proposal now floating in the OpenJDK community. Another success metric of the plan is reducing the fragmentation of highly-optimized code in the code cache. By extending Java’s compiler control mechanism to mark certain methods as hot so they could compile into the hot code heap, the proposal would separate code that is known to be hot, decrease fragmentation of selected code, an...
