I assume since this is with Handler and Runnable that this is in a separate thread? How to confirm?

final Handler handler = new Handler();
final int delay = 1000; // 1000 milliseconds == 1 second

handler.postDelayed(new Runnable() {
    public void run() {
        System.out.println("myHandler: here!"); // Do your work here
        handler.postDelayed(this, delay);
    }
}, delay);

Does this run in separate thread?

new Timer().scheduleAtFixedRate(new TimerTask() {
    @Override
    public void run() {
        //your method
    }
}, 0, 1000);//put here time 1000 milliseconds=1 second

Creating an anonymous class:

• Do you have to have an Interface to create the class because it seems to look like this:

InterfaceName instanceName InterfaceName() {
  // put your loved ones here;
}

An interface wouldn't take a parameter. If your class needs parameters you'd have a method with the same name as the interface that takes the parameters? I see how this works with classes but not sure with Interfaces
