Assignments for SI 543 sec 1 - Programming I (Java)

Assignment:
Answer Review Exercises R1.1 - R1.5 and write your age in binary.

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, 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 two lines of information about yourself. 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 two lines of information about yourself 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. If you would like the URL of your homepage made public, send me that, too.

Programming assignment: Due Jan 21
The purpose of this assignment is to give you practice using Java operators.

Write a Java application and a Java applet that has 2 variables to hold your 2 favorite numbers. Have the application and the applet print the results of using 6 different operators with your favorite numbers.

Hand in:

• Hardcopy of the application and its output. Circle any output that you think is wrong or that you didn't expect to get.
• Hardcopy of the appet.

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

Write an application that asks the user to guess a digit that you have chosen and tells the user if their guess is too high, too low, or correct. To get input from the user use these magic words.

Hand in:
Hardcopy of the application.
Hardcopy of 3 runs of your application, showing that your code correctly handles high, low, and correct input. (Use the Unix script command to put all your runs in one file to print out.)

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

Add code to your application so the user can keep guessing until they have guessed the digit you chose.

Hand in:
Hardcopy of the application.
Hardcopy of 3 runs of your application.

Programming assignment:
The purpose of this program is to give you practice writing loops, branching statements, and methods.

Write both an application and an applet that prints out a random number of Java programming facts, chosen from a list of 8 or more, without duplicates. Store your facts in an array of Strings. Your code must include a method that "shuffles" the array so that the facts are in a different order each time the applet or the application is run. Declare your array of Strings in main for the application and in paint for the applet. Send the array as a parameter to the method you write that "shuffles" the array.

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

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 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 program
• Be sure you give the original author credit
  • on your page
  • in your header
• On the hardcopy of your applet code:
  • highlight the 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.

examples

Programming assignment:
The purpose of this program is to give you practice using graphics drawing methods.

Write an applet that draws what you imagine something from the next millenium (3000!) will look like. (Use your imagination - it doen't have to be realistic.) Use at least 10 different methods from the Graphics2D and/or the Graphics class.

Hand in:
Hardcopy of your code.

Programming assignment: Due Feb. 14 at the beginning of class
The purpose of this program is to give you an opportunity to practice using inheritance, polymorphism, abstraction, and encapsulation.

Write another subclass of the class we designed in class. I have written a subclass - you must write two different ones. Include at least 2 constructors for your new classes and access methods for the new data. Write a Java application that creates at least one instance of each class (mine and yours - 3 classes all together) and uses access methods to print out the values of the variables. (Note: the one I wrote does not do this.) Write a Java applet that draws at least one object from each of the classes - mine and yours - 3 objects all together. (Note: the code I wrote does not do this.)

Think about 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 (sound)
• have a Graphical User Interface (GUI) and handle events
• have online help

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

Assignment:
The purpose 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.

Use the form handed out in class to make a list of all the things you can do to an applet while it is running, e.g., move to a different page, scroll the page, etc, and tell which methods are called for each thing you do. Use the ExtendedSimple applet to find out which methods are called. Do it for 2 different browsers (IE and Netscape) or 2 different kinds of computers (Mac and PC).

Hand in:
The form describing the things you tried while running the ExtendedSimple applet and which methods were called for each.

Assignment:
The purpose of this assignment is to start the project design process.

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 online help

Write a brief description of what you want to do for your project, a formal description of the program requirements sort of like the one in the handout, only not that long.

Hand in:
Your project requirements - sort of like the 3 page description of the bank project in the handout, only it doesn't have to be that long.

Finish the design process started in class.

Hand in:

1. Your revised project requirements
2. Your project design - what classes you need to implement, what variables and methods they each will have.
3. The main header for your project (see Programming Style above)
4. Your CRC cards, any prototypes you designed, and the scribe notes

  examples of GUIs

  Assignment:
  The purpose of this assignment is to get you to design and begin implementing your GUI.

  Students, start your projects!

  1. List the components, containers, and layout managers you will need for your project and draw the containment hierarchy (Sun calls it the Component hierarchy) on a separate piece of paper. (Here is the containment hierarchy for the applet used in class. Notice which method is used to set up the containment hierarchy. Think about why the containment hierarchy is set up in that method instead of the paint() method.)
  2. Start writing your code - put at least one of the components in your list into your project.

  Hand in next Monday:
  The list, the containment hierarchy, and the source code for the start of your project.
