Presentation Transcript

  1. Object-Oriented Programming and Problem Solving Dr. Ramzi Saifan

  2. Expected Background • “A one-semester college course in programming.” • I assume you can write a program in some language, understand variables, control structures, Arrays, functions/subroutines. • If in doubt, let’s talk.

  3. Course Outline • Background, basics of O-O, first Java program, • Raw materials: types, variables, operators, program control, Arrays, and Strings • Classes: declarations, constructors, cleanup & garbage collection • Packages, access specifiers, finals, class loading

  4. Course Outline (cont.) • Polymorphism, abstract classes, design patterns • Interfaces & extends, inner classes, callbacks via inner classes • Arrays, container classes, iterators • Exception handling, threads • Java I/O, networking

  5. Administrative Details • Professor: Ramzi Saifan • Office: CPE 408 • Office Hours: Sun, Tue, Thu 11-12, or knock the door whenever it is open • Email: r.saifan@ju.edu.jo

  6. Administrative Details (cont.) • Required Text: Horstmann & Cornell, “Core Java, Volume 1 - Fundamentals,” Sun Microsystems Press • Additional Online Texts: • The Java Tutorial http://java.sun.com/docs/books/tutorial/ • Thinking in Java by Bruce Eckel http://mindview.net/Books/TIJ/

  7. Administrative Details (cont.) • 15 weeks • Two 60-minute lectures per week • Course notes in PowerPoint. • Class attendance will be taken. You will be banned from the final exam if you are absent 6 or more times. • Homeworks are complementary to the lectures. • No make-up exams • Grading corrections: not later than one week from receiving your grade.

  8. Administrative Details (cont.) • Homework: 10% • Midterm exam 20% • Final exam: 30% • Lab: 40%

  9. My Policy on Cheating • Cheating means “submitting, without proper attribution, any computer code that is directly traceable to the computer code written by another person.” • This doesn’t help your job prospects. It is programming

  10. My Policy on Cheating • You may discuss homework problems with classmates, after you have made a serious effort in trying the homework on your own. • You can use ideas from the literature (with proper citation). • You can use anything from the textbook/notes. • The code you submit must be written completely by you.

  11. Course Etiquette • No cell phones • No random comings and goings • If you are sleepy, go home • If you want to read email or surf the Web, please do it elsewhere

  12. Programming Language Evolution • Machine language • Assembler • “3rd generation” (COBOL, FORTRAN, C) • Specialized (Lisp, Prolog, APL) • “4th generation” (SQL, spreadsheets, Mathematica) • “5th generation” (example, anyone?)

  13. Object-Oriented Languages • Smalltalk, C++, Java, etc… • You can make any kind of objects you want

  14. Making Java Work • It's “easy as pie” to write procedural code in Java. • It takes some discipline (an attitude) to think O-O. • It's worthwhile to do it.

  15. O-O Languages • Everything is an object. • A program is a bunch of objects telling each other what to do, by sending messages. • Each object has its own memory, and is made up of other objects. • Every object has a type (class). • All objects of the same type can receive the same messages.
