Example on how to use the Card class

Card c = new Card (4,  '' spade'');  (suit should be lowercase)   Card d = new Card ( ``Jack'',  '' club'');  - for royalty

 

Suppose x and y are Card objects.  

1) Display the rank of x:

IO.println (x.rank ());

  This will give the integer representation of the rank.  

2) Do a better job of 1)

x.printRank ();

 

3) Display the suit of x

x.printSuit ();

 

4) Display both cards,  one per line

x.println ();   y.println ();

 

5) Display the word ``red'' if x is a red card

boolean xHeart = (x.suit ()) == Card.HEART);   boolean xDiamond = (x.suit () == Card.DIAMOND);     if (xHeart | | xDiamond)   {   IO.println ( ``red'');   }

 

At this point,  initial code for programming challenge 4,  part 1 is introduced.   It is reproduced here since it was given in class:

Problem:
Read several (at least one) non zero integers & display the largest of these (maximum).  

Example
in:10 7 95 4 66 0
out:95  

in:   - 10 - 7 - 95 - 4 - 66 0
out:   - 4  

Procedure - take 1 st item,  make it the top & compare to next #.   Keep whats largest and proceed until all numbers are compared and displayed.
