  Written assignment:Due in class Monday Jan. 24
  Find the assignment in first day handout - do this assignment first!

  Programming assignment:Due Friday, Jan. 21
  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 telling what you did for Y2K. 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 of information telling what you did for Y2K 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

• Jan 17 - MLK Day - no class

• Jan 24 - Read: Chapters 4, 6, and 7
  The Nuts and Bolts of the Java Language and Handling Errors Using Exceptions.

  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 goals for the new millenium chosen randomly from a list of 8 or more. 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.

• Jan 31 - Read: Chapters 3 and 5
  Object-Oriented Programming Concepts and Creating Classes and Objects and Classes and Creating Interfaces and Creating and Using Packages

  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, 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 your class page.
  • Be sure your class hierarchy includes all the classes defined in the applet
  • Be sure you give the original author credit
    • on your web page
    • in your program header
  • On the hardcopy of your applet code:
    • hi-lite or otherwise mark the code where you made the change
    • 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.

• Feb 7 - Read: Chapter 9
  Managing Inheritance and Subclasses, Superclasses, and Inheritance and Using Graphics Primitives, 2D Graphics, the Graphics class and the Graphics2D class

  examples

  Programming assignment:
  The purpose of this program is to give you an opportunity to practice using inheritance, polymorphism, abstraction, and encapsulation.

  Write a subclass of the class designed in lecture and a subclass of your class. Use good object oriented design, including encapsulation and polymorphism. Put them both in the same file. ( Example of a subclass - there are many right ways to do this) Include at least 2 constructors for each of your new classes (one should be a default constructor) and access methods for any new data, if appropriate. 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 all the variables. (NOTE - the sample application does not fulfill the program requirements, it is just an application that prints out the values of the variables for two Vehicle3000s.) Write a Java applet that draws (using at least 12 methods from the Graphics2D class) at least one object from each of your classes. (NOTE - the sample applet does not fulfill the program requirements, it just shows how one is drawn and plays with the move methods.)

  How to do this assignment

  1. Start early and ask questions if you don't understand something.
  2. You need a Vehicle3000.class file for your code to compile. You may copy the Vehicle3000.java file 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 Vehicle3000 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 - you cannot use the one I wrote. Name them whatever you like, although 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 Vehicle3000 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. (You can have 1 partner.)

  Hand in:
  hardcopy of your new subclasses, your application, your applet and output from your application.

• Feb 14 - Read: Chapters 18
  Applets and Life Cycle of an Applet and Methods for Milestones and Applet security and JApplets and the Applet class , the JApplet class, the Applet tag for HTML and Comparing Swing and AWT applets

  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. The purpose of the second part is to have you develop the first draft of your project design.

  Using the form handed out in class and the ExtendedSimple applet to find out which methods are called when the user makes changes in the browser while viewing an applet. Note that you must test the applet on different kinds of computers. (There are Sun machines in the Media Union for students without CAEN accounts.)

  Decide on a project to work on for the rest of the class. It can be anything you want, but it must

  • use the following classes/interfaces: Color, Font, Image, AudioClip
  • have a Graphical User Interface (GUI) and handle events
  • have animation
  • have help for the user in the applet
  If you want to work in a group, 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.
  The program header describing your project and the GUI drawing.
