Labs Available for use with Java Elements
The following are copies of lab exercises from the Java
Elements
in both PDF and Postscript form. (Postscript is suggested.)
- From Chapter 2.4: A first experience with Java.
(PDF or Postscript)
Students become familiar with Java by writing a simple
program that makes use of the element package.
- From Chapter 2.5: A simple drawing program.
(PDF or Postscript)
By writing a program to scribble on a DrawingWindow,
students learn a little more about the element package
and simple loops.
- From Chapter 2.6: Draw your favorite mascot.
(PDF or Postscript)
We design our first program from scratch. The goal: draw your
favorite college mascot.

(PDF or Postscript)
The sorry tale of Mama and her three charges is brought to life in a
program that makes use of booleans, conditionals, and loops.

To exercise our talents writing recusive methods in an attempt to
doodle
in the drawing window.
- From Chapter 7.5: Packing bins.

One of the hardest problems in computer science is the development of
algorithms for packing bins. This array-based program allows the
student
to experiment with bin-packing strategies in a simple single-person game.
- From Chapter 8.7: Implementing a Curve class.
(PDF or Postscript)
We experiment with interfaces by developing a new
Drawable object called a Curve.
