Administrative Details (cont.)
 17 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.
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!
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!
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
 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

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
 Name solution space entities.
Spring 2014

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 2014

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.

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

Object Oriented Languages
 Smalltalk
 The first successful object-oriented language
 One of the languages upon which Java is based
 Java
 C++
 C#

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++.

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

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

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++
