CMPE 135: Object-Oriented Analysis and Design December 6 Class Meeting Department of Computer Engineering San Jose State University Fall 2018 Instructor: Ron Mak www.cs.sjsu.edu/~mak

Presentations Today Titans main.cpp One with the Object Jam

Final Project Submission Your project report should cover the same topics as your oral presentations, in more detail. What is your application? Architecture and technologies? How did you use design principles? How did you use design patterns? Your presentation slides. The code of your app. Due Monday, Dec. 10.

Final Exam Thursday, December 13 It will be similar to the midterm. 12:15 – 2:30 PM in ENG 301 It will be similar to the midterm. Covers the entire semester. Emphasis on the second half. Test on understanding the concepts. It will be given online in Canvas, if I figure out the lockdown browser, otherwise on paper.
