> > Preview Ground:The latest version of J**A is J**A 19. Here is a big vernacular explanation of some of the main features of J**A 19:
Virtual Threads (Preview).: This is a big innovation in J**a. Traditional threads are threads that map directly to the operating system and consume more resources, while virtual threads are lightweight and can be created in large quantities without consuming too many resources. This is a huge benefit for writing high-concurrency applications, greatly simplifying** and improving performance.
Structured Concurrency (Preview).This is a new programming model that makes it easier and safer to handle parallel tasks. With structured concurrency, programmers can more easily manage and control the execution of concurrent tasks, reducing errors and complexity.
Pattern matching for switch (Phase 2).: This feature allows you to be in:switchPattern matching is used in statements to make them more concise and easy to read. You can do it directly in:switchchecks the type of the variable and automatically converts the type without the need for additional type checking and forced type conversion.
Record patterns (preview).: This is a feature combined with pattern matching, which allows for the deconstruction of record classes directly in pattern matching. This makes it much easier to work with complex data structures.
Foreign Function & Memory API (Phase 3).: This API makes it easier and more secure for J**A to interact with non-J**A**. This is an important improvement for high-performance applications that require the use of local libraries, such as the C library.
Other minor improvementsIn addition to the above few major features, J**a 19 also includes some performance improvements and minor API tweaks.
Please note that since j**a is evolving very quickly, there may be a new version released after my last knowledge update. It is advisable to consult the latest official documentation for details of the latest version.
