From time-to-time, I have posted various bits of advice on Java coding. Some of the more general ones I've collected here.

Getting started
What is the general form of an interactive Java program
User Interfaces
How to coordinate all the various kinds and sources of user input
Scaling
Adapting a diagram or image to the size of the window; mapping between window location and the represented space
Exception Handling
How to think about reducing and processing exceptions
Color List
The thrills and travails of displaying a list of named colors.

Demo Programs

To run the demo of these various programs, download InstallJavaNotes.jar and double click it. (You must have Java installed.) The installer will unwrap itself into its current directory. Therein double click the "JavaNotes.jar" icon.
