Even threads are now virtual:past, present, future of concurrency in Java.
summary
Java now prototypes Project Loom virtual threads — cheap, user‑space threads that let applications create millions of virtual threads and treat blocking as inexpensive; default scheduler uses carrier threads equal to CPU cores and virtual threads mount on carriers. Examples show startVirtualThread / Thread.builder, a virtual-thread-per-task executor, ExecutorService now AutoCloseable for structured concurrency with try‑with‑resources, support and caveats for thread‑locals (can be disabled) and low‑level continuations for pause/resume.
