Chapter 1. 2 Objects of Arrays. In the previous chapter, we worked with an array of objects, but I also mentioned that it is possible to have an object that contains an array as an instance variable. In this chapter I am going to create a new object, called a Deck, that contains an array of Cards as an instance variable.

Deck int n. cards new Cardn. The name of the instance variable is cards to help distinguish the Deck object from the array of Cards that it contains. Here is a state diagram showing what a Deck object looks like with no cards allocated As usual, the constructor initializes the instance variable, but in this case it uses the new command to create the array of cards. It doesnt create any cards to go in it, though. For that we could write another constructor that creates a standard 5. Card objects  public Deck. Card5. 2. for int suit 0 suit lt 3 suit. Card suit, rank. Notice how similar this method is to build. Deck, except that we had to change the syntax to make it a constructor. To invoke it, we use the new command    Deck deck new Deck. Now that we have a Deck class, it makes sense to put all the methods that pertain to Decks in the Deck class definition. Looking at the methods we have written so far, one obvious candidate is print. Deck Section 1. 1. Heres how it looks, rewritten to work with a Deck object  public static void print. Deck Deck deck. Card. Card deck. The most obvious thing we have to change is the type of the parameter, from Card to Deck. The second change is that we can no longer use deck. Download Windows 7 Home Premium Oa Acer Laptop. Deck object now, not an array. It contains an array, but it is not, itself, an array. Therefore, we have to write deck. Deck object and get the length of the array. Java-UML-Computer-Science-Blog.jpg' alt='Free Deck Programs' title='Free Deck Programs' />For the same reason, we have to use deck. The last change is that the invocation of print. Card has to say explicitly that print. Card is defined in the Card class. For some of the other methods, it is not obvious whether they should be included in the Card class or the Deck class. For example, find. Card takes a Card and a Deck as arguments you could reasonably put it in either class. As an exercise, move find. Card into the Deck class and rewrite it so that the first parameter is a Deck object rather than an array of Cards. Shuffling. For most card games you need to be able to shuffle the deck that is, put the cards in a random order. In Section 1. 0. 6 we saw how to generate random numbers, but it is not obvious how to use them to shuffle a deck. One possibility is to model the way humans shuffle, which is usually by dividing the deck in two and then reassembling the deck by choosing alternately from each deck. The Java Program Card.

Since humans usually dont shuffle perfectly, after about 7 iterations the order of the deck is pretty well randomized. But a computer program would have the annoying property of doing a perfect shuffle every time, which is not really very random. In fact, after 8 perfect shuffles, you would find the deck back in the same order you started in. For a discussion of that claim, see http www. A better shuffling algorithm is to traverse the deck one card at a time, and at each iteration choose two cards and swap them. Here is an outline of how this algorithm works. To sketch the program, I am using a combination of Java statements and English words that is sometimes called pseudocode    for int i0 ilt deck. The nice thing about using pseudocode is that it often makes it clear what methods you are going to need. In this case, we need something like random. Int, which chooses a random integer between the parameters low and high, and swap. Cards which takes two indices and switches the cards at the indicated positions. You can probably figure out how to write random. Int by looking at Section 1. Deck Of Cards Java Code' title='Deck Of Cards Java Code' />You can also figure out swap. Cards yourself. The only tricky thing is to decide whether to swap just the references to the cards or the contents of the cards. Does it matter which one you choose Which is faster I will leave the remaining implementation of these methods as an exercise to the reader. Sorting. Now that we have messed up the deck, we need a way to put it back in order. Ironically, there is an algorithm for sorting that is very similar to the algorithm for shuffling. This algorithm is sometimes called selection sort because it works by traversing the array repeatedly and selecting the lowest remaining card each time. During the first iteration we find the lowest card and swap it with the card in the 0th position. During the ith, we find the lowest card to the right of i and swap it with the ith card. Here is pseudocode for selection sort    for int i0 ilt deck. Again, the pseudocode helps with the design of the helper methods. In this case we can use swap. Cards again, so we only need one new one, called find. Lowest. Card, that takes an array of cards and an index where it should start looking. Arrays+This+lecture.+Store+and+manipulate+huge+quantities+of+data..jpg' alt='Pick A Card Java Program' title='Pick A Card Java Program' />Java Card DownloadFor that we could write another constructor that creates a standard 52card deck and. But a computer program would. I am using a combination of Java. Once again, I am going to leave the implementation up to the reader. Subdecks. How should we represent a hand or some other subset of a full deck One good choice is to make a Deck object that has fewer than 5. Plague Inc Android Unlocked more. We might want a method, subdeck, that takes an array of cards and a range of indices, and that returns a new array of cards that contains the specified subset of the deck  public static Deck subdeck Deck deck, int low, int high. Deck sub new Deck high low1. NewClassDeck.gif' alt='Java Deck Of Cards Class' title='Java Deck Of Cards Class' />The length of the subdeck is high low1 because both the low card and high card are included. This sort of computation can be confusing, and lead to off by one errors. Drawing a picture is usually the best way to avoid them. Because we provide an argument with the new command, the contructor that gets invoked will be the first one, which only allocates the array and doesnt allocate any cards. Inside the for loop, the subdeck gets populated with copies of the references from the deck. The following is a state diagram of a subdeck being created with the parameters low3 and high7. The result is a hand with 5 cards that are shared with the original deck i. I have suggested that aliasing is not generally a good idea, since changes in one subdeck will be reflected in others, which is not the behavior you would expect from real cards and decks. But if the objects in question are immutable, then aliasing can be a reasonable choice. In this case, there is probably no reason ever to change the rank or suit of a card. Instead we will create each card once and then treat it as an immutable object. So for Cards aliasing is a reasonable choice. As an exercise, write a version of find. Bisect that takes a subdeck as an argument, rather than a deck and an index range. Which version is more error prone Which version do you think is more efficient Shuffling and dealing. In Section 1. 2. 1 I wrote pseudocode for a shuffling algorithm. Assuming that we have a method called shuffle. Deck that takes a deck as an argument and shuffles it, we can create and shuffle a deck    Deck deck new Deck. Deck deck. Then, to deal out several hands, we can use subdeck   Deck hand. Deck hand. 2 subdeck deck, 5, 9. Deck pack subdeck deck, 1. This code puts the first 5 cards in one hand, the next 5 cards in the other, and the rest into the pack. When you thought about dealing, did you think we should give out one card at a time to each player in the round robin style that is common in real card gamesI thought about it, but then realized that it is unnecessary for a computer program. RANDOM. ORG Playing Card Shuffler. This form allows you to draw playing cards from randomly shuffled decks. The. randomness comes from atmospheric noise, which for many purposes.
