![]() Consider the following example: try (var executor = Executors. ![]() These threads offer compatibility with existing Java code and a seamless migration path to benefit from enhanced performance and resource utilization. Virtual threads offer a more efficient alternative to platform threads, allowing developers to handle a large number of tasks with significantly lower overhead. It's thus named because it contains more tools than the standalone JRE, as well as the other components needed for developing Java applications. It contains a complete Java Runtime Environment, a so-called private runtime. Platform threads are a one-to-one wrapper over operating system threads, while virtual threads are lightweight implementations provided by the JDK that can run many virtual threads on the same OS thread. JDK (Java Development Kit) is a software development environment used in Java platform programming. ![]() With this JEP, Java now has two types of threads: traditional threads, also called platform threads, and virtual threads. This JEP intends to finalize this feature based on feedback from the previous two rounds of preview: JEP 436, Virtual Threads (Second Preview), delivered in JDK 20 and JEP 425, Virtual Threads (Preview), delivered in JDK 19. This feature provides virtual threads, lightweight threads that dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications on the Java platform. ![]() JEP 444, Virtual Threads, was promoted from Proposed to Target to Targeted status for JDK 21. ![]()
