Answer 1

Your "custom delay" classes must return the delay from the getDelay(TimeUnit timeUnit) method specified in the Delayed interface. E.g.

public class MyClass implements Delayed {
    public long getDelay(TimeUnit timeUnit) {
        long delay = calculateDelaySomehow();
        return delay;
    }
}

Note that you also need to provide an implementation for compareTo().
