Course Description

• Development of the basic concepts and techniques from Computer Science I and II into practical programming skills that include a systematic approach to program design, coding, testing, and debugging. Application of these skills to the construction of robust programs of 1000-2000 lines of source code. Use of programming environments and tools to aid in the software development process.

Course IDE

• eclipse

• Download– http://www.eclipse.org/downloads/index.php

• Tutorials– to be given by TAs & posted online

Why Java?• Half of all server application programming is

done using the Java platform

• What’s that?– enterprise software– What’s that?

• ecommerce, resource planning, etc.

• What is used for the other half?– .NET

Lab Facilities

• We will use the Computer Associates Transaction Processing Lab (Trans Lab)– http://www.translab.cs.sunysb.edu/– CS 2114 & 2126

• Login– all registered students have accounts– http://www.translab.cs.sunysb.edu/studentAcct.html

• Room combo– soon to follow

How are grades computed?• 4 Homework Assignments 36 % (9% each)• Written Midterm Exam 15 %

Wednesday, March 11th, 2:20–3:40pm• Design/Coding Midterm Exam 19 % Wednesday, April 22nd, 2:20–3:40pm• Software Tool Proficiency Quiz 5 % Monday, May 6th, 2:20–3:40pm• Final Exam 25 %

Wednesday, May 13th, 2:00–4:30pm 100 %

• Note CEAS Policy: The Pass/No Credit (P/NC) option is not available for this course.

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!

Other Important Info• DISABLED STUDENT SERVICES (DSS)

If you have a physical, psychiatric, emotional, medical or learning disability that may impact on your ability to carry out the assigned course work, please visit DSS in the ECC Building, 633-6748/TTY.

• CELLULAR PHONESPlease turn off cellular phones during class.

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 4th

What is a framework?• Groups of classes that form the basis for customization

– cooperating classes for a particular technology• ex: multimedia, the Web, databases, etc.

– used to build new applications & other frameworks– what’s Java’s application framework for the domain of GUI

development?• Swing (a framework built on the AWT framework)

Applications Using Frameworks

• How can this happen?

Framework

Application #1 Application #2

App1 calls methods of Framework objects

App2 calls methods of Framework objects

Framework calls methods of App1 & App2 objects

Other Java Frameworks

Table 1: Java Frameworks

Application Frameworks

Database JRelational

Intelligent Agents Jade, JAF, ABLE

Logging Java logging framework, Log4J

Multimedia JMF

Networking RMI

Testing JUnit, Cactus, JFCUnit, Abbot, Hansel

Web Development Struts, WebWork, SOFIA, Cocoon, JBoss, JOFFAD

XML Dom4j, JBind

Others Java Collections, BSF, Joone, ...

Framework Documentation

• Frameworks are more than just one class, but many classes working together

• Framework developers must explain how to use them all together properly– API– Tutorials

• Frameworks are open source as well as for purchase, ex:– http://www.j2eeolympus.com/J2EE/Servlets/ServletsFrameworks.jsp

– http://www.runtime-collective.com/JavaXML.html

Who cares?

• We are constantly using Java frameworks

• Think about how you might create a framework

• Gaining the ability to make frameworks will make you a powerful developer

What’s a mod?

http://en.wikipedia.org/wiki/Mods_%28youth_movement%29

Mods

• Short for modification• Change an existing game/application to

incorporate your own creative/productive/sick ideas

• Modding techniques:– change artwork, music, etc. via plugging in your own– change source code

• See:– http://www.planetdiablo.com/modding/basics/– http://www.game-mods.com/

Well known game mods

• Entirely new content– Neverwinter Nights– Starcraft– Id games

• Customizable UI components– World of Warcraft (WOW) add-ons

• Etc.

Why do we care?

• Because you will be making a game such that it can accommodate mods

• Then you will be making mods for your game

• Then you will be sharing your mods with each other

Sample Project?

Sample Project?

Why make mods?

• Because it makes you design anticipating later changes and additions to your program

• We will be making 2 types of mods:– maps (plugging in our own artwork/level design)– add-ons (providing additional UI utility)

• Both mods should be addable without program recompilation

The HW Plan• HW 0 – your contract to be academically honest and

understand rules of Project• HW 1 – Learning the necessary Java technologies for

making a mini version – GUIs– Threads– Image Processing

• HW 2– Create your Design & Documentation

• HWs 3 – 4– code, test, profile, document (some more) & deploy your game– review & update your design as well– create mods for your game

Pre-HW0 (this means today)

• Play and completely understand all the rules of the project ASAP
