public String timeTick() - Cause clock to advance one minute. If alarm is on and alarm time is reached after advance, this method returns string representing the alarm sound (hint use getSound so that duration is taken into account). Otherwise, this method returns an empty string.

How would I create this public method in Java?

This is the code where public String timeTick() will go into. I know that there are a lot of bugs and that the class is not functioning, but here is the context.

/** * This is an alarm clock that can be set to a certain time and turned * on/off. When it is on, it will "sound" and alarm when the alarm * is reached.
