Which method on Delayed interface tells how long until the delay expires?

  1. getDelay(TimeUnit unit)

  2. expire()

  3. remainingDelay()

  4. delay()

The correct answer is: getDelay(TimeUnit unit)

The getDelay(TimeUnit unit) method retrieves the delay time in the given time unit until the delay expires. Option B, expire(), does not exist in the Delayed interface. Option C, remainingDelay(), returns the remaining delay time in the given time unit, not the total delay time until expiration. Option D, delay(), is a constructor method and does not return the delay time.
