Devise another class, Billfold, which contains slots for two cards, card1 and card2, a method void addCard(Card) and a method String formatCards(). The addCard method checks whether card1 is null. If so, it sets card1 to the new card. If not, it checks card2. If both cards are set already, the method has no effect. Of course, formatCards invokes the format method on each non-null card and produces a string with the format [card1|card2] 5. Write a tester program that adds two objects of different subclasses of Card to a Billfold object. Test the results of the formatCards methods. 6. Explain why the output of your BillfoldTester program demonstrates polymorphism. 7. The Card superclass defines a method isExpired, which always returns false. This method is not appropriate for the driver license. Supply a method header and body for DriverLicense. isExpired() that checks whether the driver license is already expired (i. e., the expiration year is less than the current year). To work with dates, you can use the methods and constants supplied in abstract class Calendar which are inherited by the concrete class GregorianCalendar. You create a Calendar as follows: GregorianCalendar calendar
