Thread: Exercise 105 in Java textbook

I don't know what the objective is for this exercise. I think it over and over and I don't get it. I think it's because I'm tired, but it would be nice if I could have some help with my understanding. Here is the exercise:

By entering suitable code in place of the comment in the following main method, create a deck of cards:
 
 
    public static void main( String[] args )
    {
      Card[] deck = new Card[ 52 ];
      String[] suits = { "spades", "hearts", "diamonds", "clubs"  };
 
      int i;
 
for ( i = 0 ; i < suits.length ; i++ )
 
{
 
  for ( int k = 2 ; k <= 14 ; k++ ) 
 
  {
 
    // your code goes here
 
 
 
  }
 
}&#65279;
 
      for ( Card card : deck )
        System.out.println( card.name() );
    }

Once again, I don't know what the objective of the exercise is. I mean I know its about a deck of cards, but not what it is in terms of programming terms.

All help appreciated, ghostheadx

While andbin is technically correct, I believe the assignment is to simply complete the for loop so that 52 Card objects will be added to the Deck object, deck. Not that hard. Now, if the completed code is supposed to run so that you can test it, then you'll need to add some more code around it, but that should be obvious.

They gave me a card class under "show program details":

 
  public class Card
  {
    private String mySuit;
    private int myValue;
 
    public Card( String suit, int value )
    {
      mySuit = suit;
      myValue = value;
    }
 
    public String name()
    {

 
      String[] cardNames = 
        {
          "Deuce", "Three", "Four", "Five",
          "Six", "Seven", "Eight", "Nine", "Ten",
          "Jack", "Queen", "King", "Ace"
        };
 
      return cardNames[ myValue - 2 ] + " of " + mySuit;
    }
  }
 
  public class MainClass
  {
    public static void main( String[] args )
    {
      Card[] deck = new Card[ 52 ];
      String[] suits = { "spades", "hearts", "diamonds", "clubs"  };
 
      int i;
      for ( i = 0 ; i < suits.length ; i++ )
      {
        for ( int k = 2 ; k <= 14 ; k++ ) 
        {
          // your code goes here
 
        }
      } 
 
      for ( Card card : deck )
        System.out.println( card.name() );
    }
  }
