multithreading - Get a list of all threads currently running in Java

Question

Is there any way I can get a list of all running threads in the current JVM (including the threads not started by my class)?

Is it also possible to get the Thread and Class objects of all threads in the list?

I want to be able to do this through code.

Answer 1

To get an iterable set:

Set<Thread> threadSet = Thread.getAllStackTraces().keySet();

Performance: 0 ms for 12 threads (Azul JVM 16.0.1, Windows 10, Ryzen 5600X).
