|CS285 -- Lab 2: Message Class|
This laboratory was developed by Dr. Chris Taylor.
Build a robust Message class that describes an email message. The class should have a two pass reading mechanism. The first pass should read only the email header information from an input stream and record information about where the message is located within the file. The second pass should retrieve the entire contents of the email message. You may wish to consult the Random Access in input streams example for information on how to go to a specific location in an input stream.
Your Message class should have methods to display:
You should test your class by writing a program that reads in the email header information for all of the files in 2002Aug.zip (must unzip). The program should indicate the total number of messages in the file and the "Message summary" for all of the messages dated August 12, 2002 as well as the complete contents of the fourth email message dated August 22, 2002.
Lab report (due 4:00pm, Friday of week 4)
Your report should include:
As with any report you submit, correct spelling and grammar are required. In addition, your report should be submitted electronically following the Electronic submission guidelines. (You may wish to consult the sample report before submitting your report.) Be sure to keep copies of all your files, in case something gets lost. It may be wise to keep a diskette backup as well.
IMPORTANT NOTE: Be sure to save your program for future use. We will be using this assignment in next week's lab assignment.
Your grade will depend on quality of design, clarity of code and documentation, as well as whether your program produces the correct results. If you have any questions, consult your instructor.
