JEP 436 : Virtual Threads (Second Preview): Significantly streamline the process of writing, maintaining, and observing high-throughput, concurrent applications by introducing lightweight virtual threads to the Java Platform. This increases ease-of-use, comprehensibility, robustness, and performance. JEP 429 : Scoped Values (Incubator): Enables the sharing of immutable data within and across threads, which are preferred to thread-local variables – especially when using large numbers of virtual threads. Expanding the expressiveness and applicability of switch expressions and statements helps increase developer productivity. JEP 433 : Pattern Matching for Switch (Fourth Preview): By extending pattern matching to switch, an expression can be tested against a number of patterns – each with a specific action – so that complex data-oriented queries can be expressed concisely and safely. This helps increase developer productivity by enabling them to extend pattern matching to allow for more sophisticated and composable data queries. JEP 432 : Record Patterns (Second Preview): Enhances the Java language by allowing users to nest record patterns and type patterns to create a powerful, declarative, and composable form of data navigation and processing. The most significant updates delivered in Java 20 are: This cadence provides a steady stream of innovations, while delivering continuous improvements to the platform's performance, stability, and security that help increase Java's pervasiveness across organizations and industries of all sizes. Oracle delivers new Java feature releases every six months via a predictable release schedule. "Digital transformation leaders say they're more focused on improving time to market and the agility that can be gained with better tools that can accelerate their organization's application development initiatives." "Organizations today face increasing pressure to use their resources as wisely and efficiently as possible, which requires developers to seek tools that streamline application development while helping ensure their organizations achieve their IT security and compliance goals," said Jay Lyman, senior research analyst, S&P Global Market Intelligence.
