What is this course about?

• An introduction to procedural and object-oriented
  programming methodology. Topics include program
  structure, conditional and iterative programming,
  procedures, arrays and records, object classes,
  encapsulation, information hiding, inheritance,
  polymorphism, file I/O, and exceptions. Software
  debugging and testing techniques are emphasized.
  Includes required laboratory.

9
And?

• Think of this as an opportunity to put Java
  programming experience on your resume
• When this semester is over, you will be a Java
  developer

10
Major Course topics

• Procedural Programming Basics - Variable
  declarations and data types, assignment
  statements expressions, textual manipulation
  strings, input/output, method construction,
  conditional (branching) statements, iteration.
• Object Oriented Programming - Designing and
  constructing classes using containment,
  aggregation, inheritance, polymorphism.
• Arrays - Using arrays to collect like data as
  well as searching, sorting, and other array
  manipulations.

11
What course work is involved?

• 6 Programming Assignments
• 2 Written Midterm Exams
• Coding Final Exam
• in CS 2129

12
How are grades computed?

• Best 20/22 Lab Exercises 10
• 6 Programming Assignments 30
• 2 Midterm Exams 30
• Coding Final Exam 30
• 100

13
Whats a final coding exam?

• You will each program solutions to problems on a
  computer
• Programming problems (methods) related to HWs
• Programs will be graded based on performance
  testing
• Ex we will provide 10 test input to your
  solution
• if 9/10 input produces correct output, you will
  receive 9/10 points for that question
• 0 points for when
• work that doesnt compile
• an infinite loop
• your work never produces the correct output

14

22
Programming Language Hierarchy
23
Java and Sun

• Developed by Sun Microsystems in early 90s
• Sun manages/maintains the language
• A living language - new releases every 12-18
  months
• JVM (Java Virtual Machine)
• Program that executes compiled Java code
• Java SDK (Software Development Kit)
• Contains standard classes (files with executable
  code) pre-written by Sun that all programmers may
  use
• J2SE (Java 2 Standard Edition)
• J2EE (Java 2 Enterprise Edition)
• Java mascot Duke

24
Uses of Java

• Applications programming
• Database programming using Suns jdbc library
• Internet programming to create dynamic web sites
• XML manipulation for data and documentation
• Servlets and JSP technology
• Applets technology
• JavaBeans technology
• Java libraries exist for every high-level
  programming technology
• Security, Networking, Multi-Threaded
  Applications, Graphics, Graphical User Interfaces
  (GUIs), etc

25
Tools for Writing Java Programs

• 1st Approach the bare minimum
• edit Java source code in text editor (ex Notepad
  or Pico)
• compile source code into class files from command
  line
• can be tedious
• poor interactivity
• 2nd Approach IDEs
• Integrated Development Environment
• combines writing, compiling, running and
  debugging Java code into a single application
• eclipse, JBuilder, Visual Studio, etc.
• makes coding much more efficient and organized

26
How does it work?

• Java Source Code
• you write this
• .java files

• Compiler Program
• part of eclipse IDE
• javac Unix command

• Java Executable Code
• not readable
• .class files

• Java Virtual Machine
• part of eclipse IDE
• java Unix command

Running Java Program
27
AN IMPORTANT NOTE ON ACADEMIC DISHONESTY

• All work you submit for homework, projects, or
  exams MUST be your own work.
• If you cheat or aid someone in cheating, you will
  automatically fail this course and be brought up
  on charges of academic dishonesty without
  warning.
• NO EXCEPTIONS WILL BE MADE!

28
The mystery of the disappearing student

• Why would a student not take an exam, but remain
  registered for a course?
• Why would a student not do any programming
  assignments, but remain registered for a course?

29
Rules of thumb to remember

• 3 ½ months is not a long time
• Points are more difficult to makeup later in the
  semester
• Have the same sense of urgency for the 1st
  assignment as you would for the 6th

30
A professional attending meetings

• Professionals
• go to boring meetings
• go to boring conferences
• go to boring lectures
• are expected to learn and retain knowledge from
  these events
• BTW, hopefully you will reach the point in your
  professional career where you will look forward
  to attending lectures conferences

31
Get the most out of your (investment)

• Do your best each class
• not to fall asleep
• if you do, not to snore or drool
• not to zone out
• not to fall prey to Ill learn this later on my
  own
• to focus your brain on detail
• This course requires an attention to detail

32
And another thing

• Eat your veggies
• Be kind to children and animals
• Dont eat and drive
• Just say no to drugs
• Get 8 hours of sleep each night
• Dont punch old people
• Clean your room
• Dont play with knives and/or matches
• Dont play ball in the house

33
Our Daily Reminder

• Youre paying me to be here
• This material cannot be learned in one night, or
  even in one week
• please give me your brain
• This is your opportunity to learn this stuff
• as Computer Scientists, youll have many
  opportunities to use it
