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.

My Policy on Cheating(cont. ) �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.

Course Etiquette �Etiquette is “conduct in polite society” �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

This Course Covers: �Object Oriented Concepts �Fundamentals of Java programming language �Some Programming Skills �Software Quality �Test �Refactoring Spring 2015 Sharif University of Technology 12

Object Oriented Programming �Problem Space �the place where the problem exists �such as a business �Solution Space �the place where you’re implementing that solution �such as a computer �The effort required to perform this mapping. �E. g. think about a library, or a phonebook program Spring 2015 Sharif University of Technology 13

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 2015 Sharif University of Technology 14

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 2015 Sharif University of Technology 15

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 2015 Sharif University of Technology 16

Object Oriented Languages �Smalltalk �The first successful object-oriented language �One of the languages upon which Java is based �Java �C++ �C# Spring 2015 Sharif University of Technology 17

Java History �Java was created in 1991 �by James Gosling in Sun Microsystems �Initially called Oak �in honor of the tree outside Gosling's window �Its 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 1995 �Java syntax is similar to C and C++. Spring 2015 Sharif University of Technology 18

Java Motivation �The need for platform independent language �To be embedded in various consumer electronic products �like toasters and refrigerators �Platform independent? ! �Hardware �Operating System Spring 2015 Sharif University of Technology 19

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 independence �Creation of Applets Spring 2015 Sharif University of Technology 20

The Java technology is: �A programming language �Java can create all kinds of applications �A development environment �A compiler (javac) �An interpreter (java) �A documentation generator (javadoc) �… �Compare it to C++ Spring 2015 Sharif University of Technology 21
