First off, I'm in no way sure how this should be done, but I think I have a suggestion for how you could make it work. In a project I'm working on at the moment I use ExecutorService to handle my thread pool. I have to mention here, that I started working with threads in Java a little over a week ago myself, so I apologize if what I'm suggestion is too basic or wrong.

My suggestion is, that you could create a static boolean variable that you could use for controlling your loop. Code could look something like this:

public static boolean isRunning;

public static void main(String[] args) {

    ExecutorService executerService = Executors.newCachedThreadPool();

    executerService.execute(new Runnable() {
        @Override
        public void run() {
            isRunning=true;
            while (isRunning){
                System.out.println("hello world"); //Your loop here
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    });

Whenever you set the isRunning boolean to false the loop will stop, and the Thread will finish after a little while.

As for observer-observable classes I don't know this and I'm not sure I understand your last question.
