  1. Zero to Java in Internet Time David Davenport Computer Engineering Dept.,Bilkent University, Ankara 06533 Turkeyemail: 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. rect(a,b) f(a) r(90) f(b) r(90) f(a) r(90) f(b) r(90) r(30) f(150)r(120) f(150)r(120) f(150) r(90) f(100)r(45)f(50) Robo Examples

  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. f, r, l, p x,y drawheading f’ rect getDofM dofM Jrobo Examples f, r, l, p x,y drawheading f’, r, l, p rect, getDofM x,y drawheading, 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?
