EE-WEB Assignment 3

Program 1, 15pts.

Create a dynamic Web page that would alternate the color of the bacground among red green and blue. The same color should be used every third page reload or visit. Also during the very first visit a greeting message should be displayed inside the Web page.

The user information should be stored on the client side using the cookies technology. For the purpose of this demonstration assume that the cookie should be stored only for about one hour. You can change that after the page is graded.

Program 2, 15pts.

Install both a Java Compiler and the HTML version of the documentation on your computer. If you use solely the computer lab then get familiar with Java copliler and documentation that is installed in G:\JAVA folder as it was shown in class.

Perform a simple exercive with Java language. For your conveneince all steps are outlined with great details. Follow them closely.

• Write a program in Java that has two functions (including main) embedded in a class.
• Keep everything in one file, name the file using your family name (skip spaces if any).
• The first function should receive a String variable as a parameter, make it all uppercase and remove all intial and trailing space if any. The processed string is returned using return statement.
• Refer to the on-line Java documentation of the String class regarding what functions should be called. No loops or if statements are necessary!
• Declare a string variable in the main function and initialize with the string " this is a test string ". The quotes are not part of the string but spaces inside are.
• Call the first function from main with your string as a parameter. Grab the returned results into the same variable.
• Print the processed varialbe to the screen using System.out.println(...) The main function should have a String variable declared, call one function to get

Please note that this is a very simple program but this is your first exercise with a new programming language. Allow some extra time even though you are a very good programer and can write code in C or C++ fast.

The instructor will use Java2 SDK version 1.3 and compile your program with -deprecation option. To receive any credit your program must complie without any errors. You do not have to provide the printout of your program. The instructor will test it using his own set of data.

Homework Submission

Attach all source code in files with proper names and extensions (*.html, *.java, *.pl, *.php, .htaccess e.t.c.). Do not ZIP files together or include compiled files (e.g. *.class). In case of dynamic Web pages (JavaScript or CGI) or Java applets also send the complete URL (including http://) that points to a page on your Web site that demonstrates your homework. Send your homework via e-mail to the instructor. Please set the message subject to: web-hw3.
