Restart JPanel every X seconds (using threads?)

I have a settings tab in my program. The data that you can install there is not only changed from this panel. So I want to reload this data every 5 seconds. I think this needs to be done with additional Thread, but my knowledge of Threads is minimal. For this purpose, I already have a way to reboot.

What should I use for this (and how ...)?

Use ScheduledExecutorService :

 private final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
 scheduler.scheduleAtFixedRate(yourRunnable, 5, 5, SECONDS);

Then reload JPanelin yourRunnable(just follow the JavaDocs example).
