CS 136 Assignment 1
In this assignment you create classes to implement a deck of playing cards.
The assignment has two parts.
In part 1, you implement a Deck class using the CardInterface interface and
Card class discussed in lecture.
The Deck class should provide the following methods
public void shuffle();
// Post: Randomly shuffles the cards in the deck
public void reInit();
// Post: Refill the deck in order: 2 of clubs .. ace of spades
public CardInterface[] deal(int n);
// Pre: There are still n cards in the deck
// Post: The "top" n cards are removed from deck and returned
Of course, there should also be a constructor and any other necessary
methods, including a main() method which tests your Deck class.
The deck should be implemented as an array of Card.
The second part of the assignment is to provide a new implementation of the Card class,
and then use it in your Deck class.
The new card class, called OtherCard, should implement a card as a number
between 0 and 51, where 0-12 represents the clubs (2..Ace),
13-25 represent the diamonds, and so on.
This will require rewriting of the bodies of several of the methods in the
Card class.
The easiest way to do this part of the assignment is to copy my Card.java
file and edit it. Using OtherCard in place of Card should require only minor
modifications to the Deck class if you've been using CardInterface for the types
of variable and parameters.
The goals are to gain experience with the Java programming language,
the Metrowerks CodeWarrior Java environment and class design.
You should plan your work carefully so that you can complete part one and
begin part two in the lab.
Classes requested for assignments should always be named as in the assignment.
This is necessary for our testing of your work.
Also, Java programmers tend to follow certain naming conventions.
Constants are all upper-case, classes begin with upper-case, variable and
method names begin with lower case, using upper-case for multi-word names.
You should also follow these conventions.
Finally, names help the reader understand what you have written.
Names such as cardList, errorMessage, etc., are preferred (required?) over
names such as bozo, spiffy, X326, etc..
The program is due Sunday, February 15.
Programs are handed in by putting a folder, whose name is your
last name, into the CS136 drop-off folder on Cider Press.
The folder should contain the Metrowerks project folders for your OtherCard
and Deck classes.
The Deck class should include a main method which tests your Deck.
Always try to test your classes thoroughly.
For example, shuffle, deal some hands, re-initialize, shuffle again, etc.,
printing the deck contents after each operation.
Sample Program
Here is a sample applet which demonstrates what each method
should do. (It will display and execute only if your browser is Internet Explorer 4.0
-- or other browser that can execute Java 1.1 code, otherwise
you will simply get an error message.) Of course your program will be an
application, rather than an applet, and need not use windows or buttons.
