| Jcrossclient | A java front end to Crossfire, the multi-user game |
| Jdrill | A java program to help study Japanese Kanji |
| utfconvert | A java program to convert charset encodings (eg: UTF->EUC) |
| Xpm.java | An .xpm format reader for java |
| UserPrefs.java | java class for loading user preferences in an application. Docs here |
| Listor | A free table-like class, to list data in rows (source code). AWT based. Allows user to resize column widths. |
| FscrollPane.java | A free substitute for java.awt.ScrollPane |
| FscrollTable demo | Better yet, an AWT table class! (rather bare bones, binary only) |
| About.java | A trivial "About" box that can also be used to pop up any text file |
| jmail.java | A trivial "send SMTP" prog that uses java's "Mailto" URL handling to send email. Works with any JVM since java 1.0, I think. |
| flexilayout | A work-in-progress to give a very flexible layout widget. Allows you relative positioning to two other objects, for independant up/down, and x/y control. Does for FlowLayout what GridBagLayout does for GridLayout: Surpasses it in the extreme. Click through for the flexilayout home page. |
| jdbentry | A GUI utility to let you or a user add rows by hand to a table in a local database. Currently geared for use with MySQL, but should be easy to modify for use with Sybase, Oracle, etc. |
| jhtmlindex | A small java prog that takes a HTML page as STDIN, and spits out a simple table of contents, using OL tags. |

Okay, this is NOT JAVA! But I needed somewhere to link this from, so here
it is. This page demonstrates some methods for how to make a page that works great with both javascript-enabled browsers, AND plain non-javascript-enabled browsers. |
Better yet, for detailed examples of typical programming tasks, read the Javasoft Java Tutorial. It isn't always obvious, but if you dig in there enough, you can find the "best" way to do most things with java.
First, you have to GET a java runtime! I recommend getting one from javasoft, the people who control Java.
Currently, the more stable one is one based on the 1.2 spec. Try downloading the 1.2 standard runtime This allows things like direct running of .jar files.
The latest version is 1.3; however, currently, 1.2 is probably the most bugfree. (July 2001)
If you are taking advantage of a new java class in later runtimes, that simply is not present in older runtimes, you can choose to enable or disable features depending on whether the new class is accessible.
Download and compile parent.java and aux.java, two simple classes. Run 'parent' to see it use the 'aux' class. Then remove the 'aux.class' compiled class, and run 'parent' again. It will run differently, because it detects that the aux class is not available.
Generally, if it isn't more then 10 megabytes, it probably doesn't have the extra support.
Now you have to do some annoying extra setup. Go to my Unicode setup pages, then come back here to finish up.
If you have a newer java 1.2-based runtime, you should be able to run most, if not all, of my programs "directly". That is to say, with a single click in a GUI environment. Some platforms require a little more setup than others, but once you are done, you should be able to run the ".jar" file just like it was any other program.
Read the java 1.2 details on how to set up one-click operation.
