These are various small pieces of code that I created over the years for some purpose or other, mostly in Java. Some of them may be helpful to others, so I've put them here for wider access.
| If any of my code snippets and examples has been helpful to you or your company, and you feel like expressing your gratitude beyond saying Thank you, please note that I have an Amazon Wish List containing several inexpensive items, or you can contribute directly via PayPal. |
- ExprJava is a Java class that evaluates a mathematical expression by using a recursive-descent parser. It also handles variable substitution, and is useful for evaluating user-entered expressions.
- WhoisLookup contains an implementation of a WHOIS lookup, based on the Apache Commons Net library (which has some limitations)
- WebSockets shows how to use web sockets and server-sent events between a web page and a Java web app
- JSPWiki plugins
- These use the pre-2.11 API, so will not run out of the box with the latest JSPWiki releases. I hope to get around to updating these in Q2 2024.
- HighlightPlugin displays code blocks with syntax-coloring.
- LanguagePlugin displays content on a web page according to the browser's language setting.
- JavaDocPlugin links Java class names to their respective javadocs.
- EvaluatePlugin evaluates numerical expressions and displays the result.
- AntTask shows how to extend Ant with custom tasks
Some
applets from way back when those were still a thing, mostly written by other people, resurrected here so they don't get lost.
- SimpleMandel is a Java applet for displaying Mandelbrot sets of different exponents. It can also be run as an application via the command line, since applets are obsolete.
- HexCalc is a simple calculator with binary, octal, decimal and hexdecimal modes
- Martin Minow's SunSphere applet shows a picture of the rotating earth, complete with sunlight and night shadow
