Oct. 7: Graphics and Event Handling in Java

Readings: Chapter 1
Slides
Examples

SpringBreak - First Java program demonstrating simple mouse event handling

Oct. 7/8: Java Lab 1 - Introduction to Java

Handout

Oct. 9: Objectdraw graphics

Slides
Examples: These examples show how to define a class containing a constructor that uses graphical objects to create a simple drawing of a stick figure.

Stick figure - This version uses integer literals when constructing the shapes. It is easy to create, but hard to modify since it is not clear how the numbers relate to each other.
Stick figure 2 - This version uses named constants. This results in a longer program, but we can change a single value, like the size of the head and have that change propagate to the sizes and locations of all the shapes.
Stick figure 3 - This version has a location parameter in the StickFigure constructor. This allows different stick figures to be drawn at different locations on the screen. To accomplish this, the names used to represent the locations of the body parts must be changed to variables since they do not have a single value. Each stick figure has a different value for where its head should be, for example.
