    Default Two-dimensional Array representing playing cards

    My two-dimensional array is:
    String[][] cards

    The first dimension is to represent the suit and the second dimension will represent the type of card(from ace to King)

    I want the constructor to take one parameter, which will represent the suit of the trump. Then the cards should be given the following values based on the trump suit:
    Non trump from 2 to 10 = 1 point
    non trump jack = 2
    non trump queen = 3
    non trump king = 4
    non trump ace = 5
    any trump card = non trump value + 1

    How do I assign these values so that I can print out the methods:

    returning the trump suit, by name
    I used:
    [code = Java]
    String get_trump_suit()
    {
    return trump_suit;
    }
    [/code]

    another method printing the whole deck of cards, suit by suit, with the value for each card.

    And finally, a method taking a String as a parameter representing a suit, and returning the total value of the cards in that suit.

    I need help getting started in this program! Thank you.

    I know how to use classes and objects but I am not good with the arrays. I am not sure how to assign the suit for the first dimension because I also had to create a single dimensional array for the suits. So can I put that single dimensional array into the first dimension of the multi dimensional array. and also would I need to define all of the cards for the second dimension? or is there an easier way

    how to assign the suit for the first dimension
    Define int varaibles like this to use as the first index into the 2 dim array
    final int ClubIdx = 0;
    final int DiamondIdx = 1;
    etc
    ...
     
    cards[ClubIdx]  is the one dim array holding the Clubs
    cards[HeartIdx][0]  is the first Heart card

    would I need to define all of the cards for the second dimension?
    Depends on how the array is used. Each second dim can be a one dim array of different size. For example
    cards[ClubIdx].length does not need to be the same value as
    cards[SpadeIdx].length
    If you don't understand my answer, don't ignore it, ask a question.
