Is it possible to interrupt a thread in the Thread List?

Question

Java

I have a Thread List. Each thread executes Runnable. Is it possible during the execution of the first thread to interrupt the execution of, say, the third? If yes, how should it look like?

Answer 1

A thread must manage its own lifecycle on its own. The other thread can only send signals to it, changing the shared state. Use a volatile variable or one of the synchronization primitives.
