Had I not provided these explicit names in the example (which the original example in the Java Tutorials did not do), they would have been referenced by the more generic names “Thread-0” and ...

The main thread is a good example of a non-daemon thread. Code in main() will be always be executed until the end, unless a System.exit() forces the program to complete.

Virtual threads, revealed in Java's Project Loom and generally available with the Java 21 LTS, promise unparalleled scalability, simplified asynchronous coding and more efficient resource utilization.

Java virtual threads are much lighter and more efficient than traditional operating system threads, and excel at handling blocking operations. Unfortunately, despite their advantages, virtual threads ...

JDK 21's virtual threads are a major leap forward for Java's concurrency model. Previously, Java relied on OS threads, which were resource-heavy, limiting how many threads could run concurrently.
