Welcome. Optimised for IE4 and above.

ALL THE JAVA APPLETS BELOW ARE FREEWARE

ENHANCE YOUR PAGE WITH JAVA

These Java applets free to use on personal web pages. Also available at no charge to non profit making orginisations.
If you think you would like to use any of them please download the jar file which includes all the Java classes required for the applet to run. Then copy it to the same directory that your web page is in and amend the HTML using the examples below as a guide. All I would like in return is that you include a link to me on your page and acknowledge my authorship. NB links are included on the first two applets.

NB I have assumed in all cases that you will be loading all required files into the same directory as your Web page.

Image Link Java applet HTML
Got loads of graphical links on your page but not enough room to for them all to be seen. This applet circles through your images and the associated links. All you need to do is enter the URLs , image name and any caption you wish into the HTML code.

PS don't forget to enter the redval, greenval and blueval values to get a better background colour than I have!

Download newImageLinker.jar 7Kb

3dText Java applet HTML
If you've ever wanted to add some 3D text to your page but don't have a graphics editor that can do the job this might be the answer for you.

See also 3dTextTest for full instructions and auto generated HTML.

"Cool!" - javapowered.com

Download 3dText.jar7Kb

Text Link Java applet HTML
The same as ImageLink but without the images. Takes up very little room on your page. NB with both of these you decide on the speed

Download TextLink.jar6Kb

Wiggle Java applet HTML
Ok this is a bit of fun but really good at making a short caption or heading stand out.

Sorry no Java no wiggle!

Download Wiggle.jar 5Kb

Scroller Java applet HTML
Do you ever need to add information at short notice to your site? But don't want to re design. With this applet simply type in your message(s). Really eye catching without being too gimmicky. Review below from Freewarejava.com

"Horizontal-then-vertical scrollerfreewareNew!
This unique Java scroller scrolls your messages first from left to right into view, pauses, then scrolls up and away. Very interesting. "

StickMan Class java source
This is one for the programmers. If you've ever needed to include a "Stick man" in an applet or application you'll know what a pain it is to have to re calculate all those co-ordinates every time.

Methods (so far)are move(int x,int y),
translate(int x,int y)and grow(int increase). The constructor method takes three arguments StickMan(int height, int x,int y). Move and grow are used in the demo.

HTML Samples

Image Link Java applet

The code below is the HTML code used to include the Image Link Java applet on this page.
Change the entries after VALUE= to your own values but remember to include them within the quotation marks. <PARAM NAME="imgPause" VALUE="2000"> controls how fast the images change. 2000 is about 2 seconds. Using transparent gifs can be very effective especially if you choose to make the applet background colour the same as the web page's.
You can include more or fewer links if you wish. If you wish to use more follow the format below up to and including:-

Any more will be ignored.

3dText Java applet

Below is the HTML for this applet for you to cut and paste. For more information go to3dTextTest where you'll find another handy applet which will take some of the guess work out of the parameters you need to change. The only parameters not covered there are XOFFSET and YOFFSET which basically allow you to position the text anywhere you want within the applet. Please bear in mind if you change these parameters you'll have to calculate the applet width and height for yourself. As a guide if you change XOFFSET to "10" you'll need to increase the applet width by 20.

Text Link Java applet

Instructions basically as for the image links Java applet except you have no images to worry about.

Wiggle Java applet

You can set the parameters fontsize, intext and pause. The first two should be self explanatory. Please note, however that the lower the value for pause the faster the animation. One point to note. See the phrase Sorry no Java no wiggle! This is a message for people whose browsers can't run Java applets. You can include a similar message in any of the above HTML by entering it in a similar position.

<APPLET CODE="Wiggler.class"
align="top" width="320" height="50" archive="Wiggle.jar">
<PARAM NAME= "fontsize" value="21">
<PARAM NAME="intext"value="Your text here! Your text here!">
<PARAM NAME="pause" value="50">
Sorry no Java no wiggle!</applet>

Scroller Java applet

Simply replace the text0 etc values with your own text. You can enter as many or as few text valuesas you wish but don't forget to enter the number of lines you have at the"LINES" value. When doing this please note that if your last line is text11 LINES will be equal to 12 because we're counting from 0. SPEED controls the speed of animation and PAUSE the pause between horizontal and vertical scroll. You can now also set the colours for the background, text and shadow.
