card1 == card1:	true
card1 == card2:	true
card1 == card3:	false
card1 == card4:	false
card1.equals(card1):	true
card1.equals(card2):	true
card1.equals(card3):	true
card1.equals(card4):	false

Explaination:
- card1 is both == to itself (since it references the same object) as well as equals
- Since card1 and card2 refer to the same object, both cases are true
- card1 and card3 reference different objects, so == gives false.  They are equivalent objects by our definition, though, so equals returns true.
- card1 and card4 reference different objects that are also not equivalent, so both comparisons give false.
