1. Zero to Java in Internet Time David Davenport Computer Engineering Dept., Bilkent University, Ankara 06533 Turkey email: david@bilkent.edu.tr

2. Introduction Programming classes (mandatory!) –computer literacy –basic programming –object-oriented systems –event-driven GUI’s Desire –get students up-to-speed quickly –justify by focusing on engineering skills

3. What to Teach & Why Engineers today should –be technically competent –be able to communicate & work in team –be confident in locating & applying knowledge –be motivated to follow tech. & continue learning Programming as a vehicle –form of communication, done in teams –complex systems, mistakes cheap!

4. What to teach & Why Engineering relies on methodologies –Only apparent for large problems! Teach –OOP first? –Structured programming first? Which language –C/C++, Pascal/Delphi, etc. –Java (consistent OOP, complex?, Internet)

5. Course Organisation First semester CS101 –conventional lecture/lab (text-based progs.) –Robo & Jrobo… (concepts) Second semester CS102 –reduced lecture/lab (GUI progs.) –Design project… (eng. skills) Software Quest InSites

6. Design Projects Semester-long group project Group & project selection Organisation –Four stages: requirements, GUI, detailed design, implementation –submit report, make presentation, rewrite Use commercial IDE Tap enthusiasm, Internet, … (don’t tell, they learn)

7. Tools: Robo Robo: little robot with pen… Basic commands: f(x), r(x), l(x) & p Interactive start… Reflection - need a easy life! Introduce –comments, methods, parameters... –top-down design, pre/post-conditions Design, not experiment (right-first-time)

8. Robo Examples f(100) r(45) f(50) r(30) f(150) r(120) f(150) r(90) rect(a,b) f(a) r(90) f(b) r(90) f(a) r(90) f(b) r(90)

9. Tools: Robo The Robo environment...

10. Tools: JRobo OOP - natural view & facilitates reuse Examples - person, car, tv … & Robo JRobo class & use Adding methods & properties Composition - wallets & cellphones Inheritance & Polymorphism - scale & colour The JRobo environment...

11. Jrobo Examples f, r, l, p x,y draw heading f’, r, l, p rect, getDofM x,y draw heading, dofM f, r, l, p x,y draw heading f’ rect getDofM dofM payout recieve cash owner

12. Tools: JRobo The JRobo environment… (a full Java IDE) –hide syntax at beginning, enforce good practice!

13. Concluding Remarks Use programming to teach engineering skills Tools help clarify concepts Projects help develop skills –Napster & ICQ clones, physics & optics workbenches, online games, shops & dating... –Variable quality (focus more on design) –but energy, enthusiasm & work evident! Java & Internet motivate Extra time & effort, but worth it?
