Copy the hierarchy in ./classes to some directory in your CLASSPATH.
This will be sufficient to allow you to use them immediately.

For applets, these classes will only work in browsers that support the
Java Platform 1.1.  For such browsers, the directory hierarchy should
be placed in the same directory as the applet.

To compile the source code, issue the command:

javac -d DIR *.java

where DIR is some directory in your CLASSPATH
