Do I need to stop a Thread?

Question

I'm trying to implement a separate Thread in my project. Every hour a scheduler starts a thread to get files from a server and store them in my database.

My code works as it should. Since the scheduler starts a new Thread every hour, I don't know if I need to stop the Thread manually or not?

 try {
        Runnable task = new MyClass();
        Thread thread = new Thread(task);
        thread.start();

 } catch (Exception ex) {
        System.err.println("Exception-Thread: " + ex.getMessage());
 }

My Class (runnable)

  public class MyClass implements Runnable {
        @Override
        public void run() {

            try {
                //Do stuff...
            } catch (Exception ex) {
                System.out.println(ex.getMessage());
            }
        }
    }

Answer 1

If you do not have a permanent loop or something similar inside the Runnable, then no you don't need to.

Answer 2

As long as the thread has not chance of doing infinite loop Such as using while loop. Thread will stop once all the tasks in Runnable are done.
