A standard deck of playing cards consists of 52 cards. Each card has a rank (2, 3, ..., 9, 10, Jack Queen, King, or Ace) and a suit (spades?hearts . clubs or diamonds .). You will create a class called StandardCard that will simulate cards from a standard deck of cards. Your class will extend the Card class (provided). The ordering of the cards in a standard deck (as defined for this assignment) is first specified by the suit and then by rank if the suits are the same. The suits and ranks are ordered as follows: suits: The suits will be ordered diamonds ?
