What is the correct way to run an asynchronous method inside a service?

Question

Java

There is a service like this:

@Service
public class SomeService {
     ...
     private void asyncMethod() {
           while(true) {
               ....
               queue.poll();
              ....
          }
     }
     ....
}

how to properly run asyncMethod in a separate thread after service initialization?
Is there an option other than new Thread(this::asyncMethod).start() ?
