Question

Yes you have told me to use enums but my teacher JUST told me I'd fail if i did enums. she wnats me to do it in a 2d array

          //If they dont want to keep card 1..then redeal
          //So on and so forth

               card1=card6;

          System.out.println("1)"+card1);
          System.out.println("2)"+card2);
          System.out.println("3)"+card3);
          System.out.println("4)"+card4);
          System.out.println("5)"+card5);
          //Give user the new cards
          System.out.println("Here are your (new) 5 cards");
          System.out.println("1)"+card1);
          System.out.println("2)"+card2);
          System.out.println("3)"+card3);
          System.out.println("4)"+card4);
          System.out.println("5)"+card5);
          //Determine what kind of hand the user has.
          String hand=poker.determineHand(card1,card2,card3,card4,card5);
          System.out.println(hand);
          //Exit the program
          System.exit(0);
     public static String deal(int suit,int rank)
          String card="";
          //Making the deck out of the 2D array
          for(int i=0;i<suit;i++)
               for(int n=0;n<rank;n++)
          return card;
     public static String determineHand(String card1,String card2,String card3,String card4,String card5)
          //Some awesome crap here to determine what kind of hand the user has
          String hand="You have a ";
          //If it is a flush
          return hand;
}Inside those two for loops, what exactly should i do? I'm thinking have an array cards[][] and in each position like cards[0][0]//that is 2 of clubs
that sound right or something? Then impliment something to shuffle?

This is probably how you would've done it 10 years ago...
