Java Basics

Background, Hello World in VS .NET, identifiers, variables, expressions, assignment, operators, output strings, console I/O, dialog I/O, Objects, Simple classes (parameters, overloading, constructors), debugging

Introduction, Java Overview
CS1 Java examples set at CFX
Hello World in VS .NET
The J# execution model: executing .EXE's, FxCL & JCL, supplemental UI Library
Java Basics: How much do you weigh on other planets?
- Version 1: A simple program, comments, semicolon, output
- Version 2: Variables, assignment (=), arithmetic operators, string concatenation
- Version: if, else-if
- Version 3: Precedence, parenthesis, type cast, named constants, while loop
- Version: for loop
- Input using JOptionPane, including number formatting. Also see CFX examples of JOptionPane and number formatting
- Input using BufferedReader for console input. Also see CFX example
  (Several of the above programs can also be found in CFX grouped under Weight Calculator)
First BlueJ Program. Also see CFX Hello World program
Objects and Classes (has link to BlueJ shapes example)
Other reasons to use methods
Output using Strings. Also see CFX Strings examples
The if statement
Loops: while, do-while, for
break and continue
Types, ASCII table
Shortcut operators, Logical Operators, Precedence, ++ and --
Objects and Classes: Object Oriented vs. Procedural Programming
- Development of Date examples class handout.doc
- Example of variable and parameter scope in Confuse.java
- Example (MS Word) of Employee class, along with classes Date, EmployeeDemo, IODisplay
  (See in-class examples for the source code), and some further notes on static methods and variables.
- See also a few diagrams illustrating object references and how they change
Debugging
Simple File I/O

Arrays & Data Structures

Motivation, Solving Using Arrays, Syntax, Usage,
Examples
Searching & Sorting
2-D Arrays
ArrayList
J# Example: Banking App example with file IO (from “2. The J# Language”)

GUIs and Object-Oriented Design

Introduction to GUIs:
(Move to here the Visual Sorting SWING demo from “4. Component-based Programming”, comparing Swing to VS libraries)
Event-driven programming, code-behind, simple calculator, Winforms, controls
Winforms & Controls, Part 2: slideshow App, StudentInfo App, list box, Baby Browser
Lab 4: GUI of Attendees App using arrays
Exception Handling (from “10. Debugging and Testing) (needs to be expanded)
Object-oriented Design with inheritance & interfaces (some simple UML )
Class Design 6 rules (needs to be expanded)
Inheritance , Polymorphism, Overriding equals (needs to be expanded)
Interfaces : design by contract, comparable interface (needs to be expanded)
Lab 5: Object-Oriented Design: attendees App, sortable by different fields

AP Marine Biology Simulation (MBS)

Overview, Architecture, design, focus on Core classes (ppt, demos)
Lab: Role-playing
Lab: Running simulation, looking around the code, javadoc (instructions, all files)
Extending the MBS [new fish, environments, display] (ppt, demos)
Lab: Adding Predator Fish, Circle Fish (instructions, all files)
Testing (ppt, demos)

Other

Wrap-up (ppt)
Recursion: a method directly or indirectly calling itself
The J# execution model, part 2
(CLR), GAC, looking at .EXE's using ILDasm
Lab 2: Looking inside Banking Application: JCL vs. FxCL, ArrayLists, GAC & ILDasmComponent-based programming:
Command-line development (“Ouch” app), Banking App built as components
