How does Java makes use of multiple cores? (4 answers)

Closed 8 years ago.

When I use several threads in my Java application, dies the VM automatically run these threads on different cores?

Answer 1

The JVM isn't involved in that decision (any more, it was way back in Java 1.2). It's down to the OS now. So if you're using multiple threads, the OS can put them on different cores depending on its scheduling algorithms. (See also this question and its answers.)
