CS 4773 Object Oriented Programming, Spring 2000
Assignment 1

Due Wednesday, January 26

Assignment 1 has 7 parts.

Part 1:
Make sure your account is set up for compiling and running Java applets using Java version 1.1. Most of the applets you create in this course will not run under Java 1.0x because of the change in the event model. From your account execute the command

  java -version

  java version "1.2.1"
  Solaris VM (build Solaris_JDK_1.2.1_02, native threads, sunwjit)

Part 2:
Make a private directory for this assignment and copy the files /usr/local/courses/cs4773/spring2000/assign1/* into this directory. Edit the .java file and change my name to yours. You can compile the program with
javac ShowD.java
and run it with
appletviewer ShowD.html
or you can use the makefile which you copied.

Make sure that you can run this program successfully. Run the program and input 0.01 and observe the result. Next try the input 0.011. Think about why you got the result that you did.

Part 3:
If you have not already done so, set up a web page on your account. Make a directory in you home directory called public_html. The permissions on this directory should be drwxr-xr-x. Your home directory must also have these permissions.

Create a world-readable file in this directory called cs4773.html. This will be your course web page. I will use it to run your programs. You can use the file with the same name in /usr/local/courses/cs4773/spring2000 as a model. Just change the appropriate lines. There are two places where my name should be changed to yours and one place where my username should be changed to yours. You may add additional information to this file, but it should be uncluttered and load quickly (no graphics).

Part 4:
Start up your favorite browser and determine the version of java it is using. To do this, access this web page and click here.

A yellow box should appear on the screen with some text describing the version of Java that is being run. The version should be at least 1.1.3. If not, you will have to use a different browser.

Part 5:
Create a subdirectory under public_html called cs4773_programs and a subdirectory under this called assign1. Each of these should be world read and execute. Copy your .class and .html files from Part 2 into this directory and make sure they are world readable. Do not put your .java file in this directory. Make sure that you can run your applet from your browser. You should already have a link to this program in your course web page.

Have a friend try out your applet from a different account to make sure that you set your permissions correctly.

If you are having trouble getting it to work and you think it might be a problem with the browser, go to the Prototype Course Web Page and try Assignment 1 from there.

Part 6:
When everything is working correctly, send me email telling me this so that I can try it out. If it is not working before the due date, send me email by the due date describing your progress.

Also in your email:

• Describe the results of running your program with inputs 0.01 and 0.011 and explain why any results are different from what was expected.
• Tell me what browsers you are using and the version of Java reported for each.

All email to me must have a subject line. The subject line for the email described above should be CS 4773 Assignment 1. If you are not prompted for a subject line when you send mail, insert the following alias in yout .cshrc:
alias mail mailx
