IB CS Java - for the Core Syllabus for exams in 2014

Introductory Comments   by Dave Mulkey , Germany, Aug 2012

These sample programs run in Processing, a free Java IDE.  They require a bit of conversion (not very much)
if you wish to run them in a standard Java environment.  Please read the Introductory Comments
if you are unsure how to use this site.  If you are new to Processing, you might want to read this page.

OOP Samples 

They following programs demonstrate the use of OOP techniques.

    IBIO Test - code for the IBIO commands in JETS 
    Fractions - a program to add fractions which are stored as Objects
    Blackjack - a simple card game simulation, using a CARD class
    GUIdice - a dice simulation with OOP techniques  (only works in Processing ver 2 - not in ver 3)
    Stack - uses a STACK stored in a Linked-List to reverse a list of words
    BinaryTree - alphabetical binary search tree

You may find it easier and/or more satisfying to write OOP code in BlueJ,
which clearly shows separate classes and connections between them.
If you do switch to BlueJ, keep in mind that it uses STANDARD Java,
and is missing some of the Processing commands that make things easier.
Most of your code will work the same, but you will need to write
standard class headers and a main method.


GUI, Graphics and other Interesting Commands

You may find the following demonstrations useful for project work.
These examples are presented in Processing programs, but you might
wish to use NetBeans for project work, as it makes lots of GUI and
other OOP construction faster and easier.   Specifically, NetBeans
supports Swing components.  Swing components are more complex
to use, but provide numerous helpful, advanced features.

   Buttons and Pictures - Uses AWT Buttons to display pictures (only works in Processing ver 2 - not in version 3)
   NumList - input numbers and store them in an AWT List box (only works in Processing ver 2 - not in version 3)
   Quiz Questions with Parallel Arrays - quiz questions with pictures (only works in Processing ver 2 - not in version 3)

Storing Data in Files

   Email List - saves names and email addresses in a disk file
                       By default, data files land in the Processing.exe folder
                        with the processing program - NOT in the Sketch folder

   Dates List - uses "loadStrings" and "saveStrings" to read and write
                      from a text file.  The loadStrings and saveStrings commands
                      are sensible and store the .txt file(s) in the Sketch folder.
