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 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 Fall 2014Sharif University of Technology12

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 Fall 2014Sharif University of Technology13

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” Fall 2014Sharif University of Technology14

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. Fall 2014Sharif University of Technology15

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 Fall 2014Sharif University of Technology16

Object Oriented Languages Smalltalk The first successful object-oriented language One of the languages upon which Java is based Java C++ C# Fall 2014Sharif University of Technology17

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 becaused of Java Island in Indonesia because there was already a language called Oak.
