• Sep 10 - Read:
  The "Hello World" Application and The "Hello World" Applet and the Applet tag for HTML.
  

  Programming assignment:
  The purpose of this assignment is to introduce you to beginning Java programming concepts and to get you to learn how to edit, compile, and print Java source code files, how to run Java applications, how to run Java applets, and to learn how to print the output of your Java applications and applets.

  Write a Java application, using the class style, similar to the HelloWorldApp.java in the tutorial that will print your name and three lines listing your favorite games. For the hierarchy for your application you can put
  Object - YourApplicationClassName
  Write a Java applet, using the class style, similar to the HelloWorld.java applet in the tutorial that will print your name and three lines listing your favorite games on one of your web pages. For the hierarchy for your applet you can put
  Object - Component - Container - Panel - Applet - YerAppletClassName
  

  Hand in:
  

  • Hardcopy of the application and its output
  • Hardcopy of the applet and its output
  • email me the URL of your applet

• Sep 17 - Read:
  The Nuts and Bolts of the Java Language.

  Programming assignment:
  The purpose of this program is to give you an opportunity to practice loops and branching statements.

  Write both an application and an applet that prints out a random number of things you would like to get for Christmas chosen randomly from a list of 8 or more. Items must be displayed in a random order. Be sure no item is displayed more than once.

  Hand in:
  Hardcopy of both the applet and the application.
  Hardcopy of 3 runs of your application.

• Sep 24 - Read:
  Object-Oriented Programming Concepts and Creating Classes and Objects and Classes and Creating Interfaces and Creating and Using Packages

  The evolution of the Point class.

  Programming assignment:
  The purpose of this program is to give you a chance to look at other people's Java code, and see how they organize their classes and use the API, and also to give you some ideas about possible projects you might want to do for the class.

  • On the web, find source code for a cool applet. (If you choose an applet written in Java 1.0, 1.1, or 1.2, you may get a "deprecated method" warning when you compile it. Just ignore the warning for this assignment.)
  • Format it according to my style specifications
  • Modify it in some way.
  • Put it on a web page.
  • Be sure your class hierarchy includes all the classes defined in the applet
  • Be sure you give the original author credit
    • on the web page
    • in your program header
  • On the hardcopy of your applet code:
    • highlight the changes (not the style changes) you made in the code (or mark them in some other way)
    • underline all the class names
    • circle the instance variable declarations
    • put a rectangle around the method definitions
    • put a * next to all the class variables and class methods defined or used.

  Hand in:
  the annotated hardcopy of your applet code with the URL of the original applet and the URL of your modified applet.

• Oct 1 - Read:
  Object Oriented Concepts and Classes and Inheritance and Using Graphics Primitives and the Graphics class

  Programming assignment:(Due Fri. Oct. 12)
  The purpose of this program is to give you an opportunity to practice using inheritance, polymorphism, abstraction, and encapsulation.

  (1)Write a subclass of the class designed in lecture and 2 subclasses of your class. Conceptually, you are designing a person type in the game and 2 different kinds of that person type. (For example, your subclass might be Royalty and subclasses of that might be King and Duke. Your people must be modern day types.) Each subclass must have at least one new instance variable. Each subclass of your subclass must call the superclass draw method. All Persons must fit in a bounding box 400 pixels high and 250 pixels wide. (They don't have to fill the bounding box, they just can't be bigger than that.) Your Person should stand on the bottom of the box - conceptually, standing on the ground. Your Persons must be drawn facing front. (You will not be graded on your art.) All your person classes must have a default constructor - a constructor that takes no parameters. Include at least 2 constructors for each of your new classes (one should be a default constructor) and access methods for the new data, if appropriate.
  (2) Write a Java application that creates at least one instance of each class you wrote and uses access methods to print out the values of the variables.
  (3) Write a Java applet that draws at least one object from each of your classes.

  How to do this assignment

  1. Start early and ask questions if you don't understand something.
  2. You need the .class file for the base class for your code to compile. You may copy the .java file for the base class to your directory and compile it there, BUT YOU MAY NOT CHANGE ANYTHING. If you want more functionality, you have to write it into your subclass. (Treat the base class as if it was a class in the API - don't hand in the source code for it, don't modify the source code for it, use it in your class hierarchy. )
  3. Choose your own names for your subclasses. Name them something meaningful - names like Subclass1 will not be acceptable.
  4. Remember that you inherit all the variables and methods from the super class, so you can just use those variables and code. You don't need to write them over in your class. That is whole point of inheritance.
  5. The graphic representation of your Person doesn't have to be anything fancy. No points will be taken off for bad art.

  Think about what you want to do for your project for the rest of the course. (You can have 1 partner for the project, but not for this assignment.)

  Hand in:(Due Fri. Oct. 12)
  Hardcopy of your new subclasses, your application, your applet and output from your application.

• Oct 8 - Read:
  Handling Errors Using Exceptions

  Example applet Exception

  Programming assignment:
  work on your Person code

  Hand in on Friday: Oct. 1 assignment

• Oct 15 - Read:
  Applets and Life Cycle of an Applet and Methods for Milestones and Applet security and the Applet class , the Applet tag for HTML and Comparing Swing and AWT applets
  Applet life cycle from the browser's point of view

  Assignment:
  The purpose of the first part of this assignment is to help you get a feel for how applets run in a browser and to help you understand the purpose for each of the applet methods. Do the first part by yourself - no partner. The purpose of the second part is to have you develop the first draft of your project design. If you are going to have a partner, you must do it together. (Hand in one copy with both names on it.)

  The form handed out in class contains a list of different things you can do to an applet while it is running, e.g., move to a different page, scroll the page, etc. On the form mark which methods are called for each thing you do. You must make up the last 5 yourself. The ones you make up must be different from the ones I put on the form. Use the ExtendedSimple applet to find out which methods are called. (You can find the version of the browser in the Help menu.)

  Decide on a project to work on for the rest of the class. It can be an applet or an application or both and it can do anything you want, but it must

  • use the following classes/interfaces: Color, Font, Image or ImageIcon, AudioClip
  • have a Graphical User Interface (GUI) and handle events
  • have animation
  • have help for the user as part of the program
  If you want to work in a group on the project, you may choose 1 partner.

  Prepare a program header for your project and a rough drawing of the graphical user interface (GUI).

  Hand in:
  The form describing the things you tried while running the ExtendedSimple applet and which methods were called for each.(do this yourself)
  The program header describing your project and the GUI drawing.(do this with your partner, if you have one)
