These Java applets were the outcome of briefly learning Java in the early 2000s as a precursor to writing a real-time internet trading platform for local authorities which used a Java applet on the client-side.

This applet loads an image file and converts the image pixels into a series of int values that can be pasted into a static int array defined in a class. For an example look at the MsgBoxIcons.java class in the framework.

This applet is a sort of IDE for Visually creating "Logo" type programs. It only resembles Logo though because you control a turtle. It supports some basic drawing stuff like pen control and forward/turning motions. It also supports loops and named variables (of type double) to allow you to produce vaguely interesting patterns. To get around the lack of access to the file system, the program can be stored and loaded by cutting/pasting from/to the source editor window.

These packages contain all the classes that are common to my Java applets. Currently it only contains UI classes for creating message boxes and modal dialogs. The message box is styled to look like a standard Windows one.

This applet is an aid to help solve Sudoku puzzles. It provides the ability to enter multiple numbers into each cell to make it easier to track the possible answers, and has a 'hint' and 'solve' feature to help you when you're stuck on the harder puzzles. It also means you don't need a pencil and rubber...
