This Java version has been superseded by my JavaScript version.
I left the Java version here to show that I've written something in Java to an objective and mildly complex specification. Better evidence of my Java / J2EE work is doing complex maintenance on an in-production quoting system in 2011 for Webdezyners, but that application is internal / private, so I can't show you that.
If necessary, see notes on compatibility and required software.
