Unfortunately, Oracle has effectively decommitted Applets. This means you can no longer run the various CMP programs in a browser. You must download them and install them.
You must have the most recent Java
JRE (Java Runtime Environment) 1.8.0_131
32-bit or 64-bit. It no longer matters which browser you use.
Oracle has effectively decommited Applets, so this Applet will no longer run online in your browser, but it is a hybrid you
can also download, install and run it on your own machine as standalone
application. It will start and run faster if you do that. It will also
work safely even if you have disabled Java in your browser.
Originally, a point was a unit of measure in the typesetting industry. A
printer’s point is 1/72.27 inch.
In PostScript a point is 1/72 of in an inch.
In Java, a point is one pixel width/height. If you had an old fashioned
low-resolution monitor with 72 dpi resolution, then a point would also mean 1/72 of
an inch. So when you ask for a 10 point Font in
Java, you don’t get what printers call a
10-point font. You get a font about 10 pixels high, which could be tiny or huge
depending on your monitor resolution.
In Java, with Graphics, a Point with a capital P, is a class
describing a location on the screen, or a location within a window relative to its
upper left corner, with an x and y coordinate. Points have two public
int fields x and y, however, the getX and getY methods return doubles.
x is measured across from the left in pixels. y is measured down from the top in pixels.
In Java, with Graphics2D, a Point2D with a capital P, is a class
describing a location on the screen, or a location within a window in user-defined coordinates, which are
much more flexible. Using AffineTransform, you can transform the coordinates to go
in any direction you want and aren’t even necessarily orthogonal.
Point2D.Float that Point2D.Double are similar to Point,
but they store the x, y in
float and double
respectively. The strange dot in the name comes about because Float and Double are inner classes of

is a Java Applet (that can also be run as an application)
You are welcome to install it on your own website.
If it does not work…
If Copy/Paste (Ctrl-C/Ctrl-V) do not work, you can turn them back on by
modifying your java.policy file. This is not for the novice or faint of heart. instructions
Your alternative is to download this program and run it without a browser.
In the Java Control Panel security tab,
click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security, configure medium security
to allow self-signed and vanilla unsigned applets to run.
If medium is not available, or if Java security is blocking you from running the program,
configure high security
and add http://mindprod.com
to the Exception Site List at the bottom of the security tab.
Often problems can be fixed simply by clicking the reload button on your browser.
Make sure the Java in your browser is enabled in the security tab of the Java Control panel.
Click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security ⇒
Enable Java Content in the browser.
This Java Applet (that can also be run as an application)
needs 32-bit or 64-bit Java 1.8 or later.
For best results use the latest 1.8.0_131 Java.
It works under any operating system that supports Java
e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32, W10-64, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
You should see the Applet hybrid above looking much like this
If you don’t, the following hints should help you get it working:
Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
To ensure your Java is up to date, check with Wassup.
First, download it and run it as an application independent of your browser,
then run it online as an Applet to add the complication of your browser.
If the above Applet hybrid does not work,
check the Java console for error messages.
If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
If you are using Mac OS X and would like an improved Look and Feel,
download the QuaQua look & feel
UnZip the contained quaqua.jar
and install it in ~/Library/Java/Extensions
or one of the other ext dirs.
Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
Try upgrading to a more recent version of your browser,
or try a different browser e.g. Firefox, SeaMonkey, IE or Avant.
