Administrative Details (cont.)

weeks

Two 80-minute lectures per week, a break in between the lectures.

Course notes in PowerPoint.Course notes available (usually)

Friday before class.Send course questions to Blackboard’s Discussion Group, personal questions to me.Slide7

Administrative Details (cont.)

Everything is attached to the syllabus. Don’t look for assignments, etc. on Blackboard. Look at the syllabus!

Homework usually weekly.

Printing slides? Three to a page, at least. Save a tree! Remove the PowerPoint background before printing. Save toner!Slide8

Administrative Details (cont.)

Attendance is not required, but…

…you are responsible for everything said in class.

I encourage you to ask questions in class. Don’t guess, ask a question!Slide9

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.”

I give students a failing

course grade for any

cheating. This doesn’t help your job prospects.Slide10

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.Slide11

Course Etiquette

Etiquette is “conduct in polite society”

No cell phones

No random comings and goingsIf you are sleepy, go home

If you want to read email or surf the Web, please do it elsewhereSlide12

This Course Covers:

Object Oriented Concepts

Fundamentals of Java

programming languageSome Programming SkillsSoftware Quality

TestRefactoring

Spring 2014

12Slide13

Object Oriented Programming

Problem Space

the place where the problem exists

such as a businessSolution Spacethe place where you’re implementing that solution

such as a computerThe effort required to perform this mapping.

E.g. think about a library, or a phonebook programName solution space entities.

Spring 2014

Sharif University of Technology

13Slide14

Object Oriented Approach

OOP lets the programmer represent problem space elements

The elements in the problem space

and their representations in the solution space

are referred to as “objects”

Spring 2014

Sharif University of Technology

14Slide15

OOP

The program is allowed to adapt itself to the lingo of the problem

by adding new types of objects

when you read the code, you’re reading words that also express the problem.

Spring 2014

Sharif University of Technology

15Slide16

OOP (2)

OOP allows you to describe the problem in terms of the problem

Rather than in terms of the computer

Objects in your code are similar to real objects

Recall the sample programs: phonebook and library

Spring 2014

Sharif University of Technology

16Slide17

Object Oriented Languages

Smalltalk

The first successful object-oriented language

One of the languages upon which Java is basedJava

C++C#

Java History

Java

was created in 1991

by James Gosling in Sun MicrosystemsInitially called Oak

in honor of the tree outside Gosling's windowIts name was changed to Java because there was already a language called Oak.

Sun Microsystems released the first public implementation as Java 1.0 in 1995Java syntax is similar to C and C++.

Spring 2014

Java Motivation

The need for

platform independent

languageTo be embedded in various consumer electronic products like toasters and refrigerators

Platform independent?!HardwareOperating System

Java Motivation (2)

At the same time, the World Wide Web and the Internet were gaining popularity.

Java could be used

for internet programming.Why?

Platform independenceCreation of Applets

The Java technology is:

programming language

Java can create all kinds of applicationsA development environment

A compiler (javac)An interpreter (java)

A documentation generator (javadoc)

…

Compare it to C++
