Java 19 released with language improvements and library enhancements

The latest version of Java has been released by Oracle. Java 19 includes a number of updates related to performance, stability, and security. 

The most significant improvements to the language itself are the ability to nest record patterns and pattern matching for switch expressions, both of which are currently in preview. The record patterns update extends pattern matching and allows for more composable data queries. Pattern matching for switch expressions allows an expression to be tested against multiple patterns.

New library tool updates include an API for invoking foreign functions and safely accessing foreign memory, which enables Java programs to call native libraries and process native data using a Java development model. A new Vector API allows Java programs to express vector computations that compile at runtime to vector instructions. 

Project Loom, which is an attempt to provide a lightweight concurrency model for Java, has also resulted in a few new features. Virtual threads significantly reduce the effort of writing, maintaining, and observing high-throughput concurrent applications. Structured concurrency will simplify multithreaded programming by treating multiple tasks running in different threads as a single unit. 

And finally, the Linux/RISC-V Port has been integrated into the JDK mainline repository, which will make Linux/RISC-V implementations easier in the future.

“Our ongoing collaboration with the developer community is the lifeblood of Java. As the steward of Java, Oracle is steadfastly committed to providing developers and enterprises with the latest tools to help them create innovative apps and services,” said Georges Saab, senior vice president of development for the Java Platform and chair of the OpenJDK Governing Board at Oracle. “The powerful new enhancements in Java 19 are a testament to the monumental work across the global Java community.”

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
