EE-WEB Assignment 6

Program 1, 30pts.

Write an application that can also run as an applet and has the functionality of a resistance calculator.

• Layout: The calculator should have a title, two input textfields, one output text field (read only but not disabled) and three buttons: parallel, serial and clear. The title should be larger and centered on a separate line. Place all other elements in the functional way.
• The application frame must be closable.
• Clicking the clear field should clear all text fields.
• Clicking the parallel button should calculate the effective resistance of two resistors connected in parallel. (OUT=1.0/(1.0/IN1+1.0/IN2))
• Clicking the serial button should calculate the effective resistance of two resistors connected one after another. (OUT=IN1+IN2)
• Error handling: perform calculations only for positive values of resistance and when input values are valid decimal numbers. Display an appropriate descriptive error message in the output field otherwise. If one of the pararel resistors is zero, the effective resistance is zero.

Your homework will be graded in the following way: The applet posted on your Web site will be tested using several resistor vaules. Not all of those values will be numerically correct. Then the application sent by e-mail as a file attachment will be compield using -deprecation option. The application will be resized to check against correct layout, and then one saple calculation will be performed.

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-hw6.
