}
public static Event getLargestEvent(Event e1, Event e2) {

}
}
Explanation:
- Call isLargeEvent() method to check whether to set pricePerGuest as Lower or Higher.
- Calculate the price by multiplying the total guests with price per guest.
- Call gettotalGuests() method to check if the event is large or small.
